Already out of custody; Officer’s 4th gun arrest in city this year
By Brentwood Police Department
Last Wednesday, Feb. 12, 2025, around midnight, a Brentwood officer conducted a traffic stop near Lone Tree Way and Williamson Ranch for expired registration.
The driver, 33-year-old Deontae Markell Alexander of Antioch, was found to be unlicensed. Further investigation revealed that Alexander, a convicted felon, was in possession of a loaded firearm, which he is legally prohibited from owning or carrying. Officers also determined the firearm had been reported stolen.
This marks the officer’s fourth gun-related arrest this year, reinforcing the department’s commitment to keeping illegal firearms out of the community.
According to localcrimenews.com, Alexander was charged with Receiving or Concealing Stolen Property, Addict in Possession of a Firearm, Possession of Ammunition, Carrying a Loaded Firearm on Person or in Vehicle while in a Public Place, and Carrying a Concealed Weapon in a Vehicle. He also has a history of arrests dating back to before 2014 by multiple agencies including Antioch PD and Oakland PD for crimes including vehicle theft, possession of marijuana over 28.5 grams, DUI alcohol with BAC over .08 and battery on a spouse, cohabitant or former spouse.
According to the Contra Costa Sheriff’s Office, as of Friday, Feb. 14, he is out of custody and on his own recognizance.

Read MoreWeidhofer Cold Case
By East Bay Regional Park District Police Department
The East Bay Regional Park District Police Department announced Wednesday, February 19, 2025, that DNA evidence has conclusively identified the murderer in a 35-year-old case that took place in Charles Lee Tilden Regional Park in Berkeley, CA.
Evidence collected from Jon Lipari, who died by suicide in Oregon in November 2024, was linked to the victim Maria Weidhofer, a Berkeley resident. She was an avid jogger and park user of Tilden Regional Park.
On Nov. 16, 1990, Weidhofer was found deceased on a trail near Inspiration Point in Tilden Regional Park. Weidhofer was found with rope around her neck and with physical signs of a struggle after she had been reported missing the night before.
An autopsy, performed at the time of the crime, found that Weidhofer’s cause of death was asphyxia by ligature strangulation and found a multitude of minor abrasions and contusions upon her person. A lengthy investigation was conducted in 1990-1991 by the East Bay Regional Park District Police Department. A suspect was not identified from this initial investigation.
In 1997, biological evidence found on Weidhofer from the suspect was sent to the Contra Costa Crime Lab for analysis. That evidence was later submitted to the Combined DNA Index System (CODIS). Among the evidence collected, during the initial investigation, was semen from which a DNA profile was generated.
In 2020, the East Bay Regional Park District Police Investigations Unit began working with the Federal Bureau of Investigation (FBI) on this case. This collaboration included the use of advanced DNA techniques. Through this investigation, Lipari was determined to be a potential suspect and became the primary suspect in 2024.
Once Lipari was identified as a potential suspect, hundreds of hours of further investigation were conducted in collaboration with the FBI, Contra Costa County District Attorney’s Office, and the Curry County Sheriff’s Office. The investigation also determined that Lipari was living in Gold Beach, OR.
In early November 2024, Lipari was found deceased in his residence by local law enforcement from a self-inflicted gunshot wound. DNA from the scene was retrieved by the Curry County Sheriff’s Office and a direct comparison was done by the Contra Costa County Crime Lab. The comparison determined the DNA profiles generated from the evidence collected at the original scene and the DNA from Lipari were a match.
There is no indication from the investigation, Weidhofer’s family, or Lipari’s family, that there was any previous contact between the victim and suspect.
“We hope that today’s development brings some measure of closure to the family, who have shown tremendous strength throughout this difficult time” said Roberto Filice, Chief of the East Bay Regional Park District Police Department. “This breakthrough comes after years of relentless investigation, and I want to personally thank our dedicated staff for their perseverance and firm commitment to seeking justice. Their determination to never give up ultimately led to solving this case, and we are proud to serve a community that stands together in the face of tragedy.”
Special thanks to the FBI, the Contra Costa County District Attorney’s Office, the Contra Costa County Sheriff’s Forensic Services Division, and the Curry County Sheriff’s Office for their collaboration, expertise, and dogged determination in solving this 35-year-old case.
In posts on X (formerly Twitter) on Wednesday Contra Costa Sheriff David Livingston wrote, “Contra Costa Sheriff’s Crime Lab played key role in the case. In 1997, lab analyzed biological evidence, generated a DNA profile, and uploaded it to CODIS database. Recently, crime lab received a reference sample from Lipari and was able to confirm that he was the suspect.
“The Contra Costa Sheriff’s Office Forensic Services Division Crime Lab is proud to assist our law enforcement partners in their investigations and help bring answers and closure to victim’s families,” he added.
During Wednesday’s press conference Contra Costa Deputy DA Satish Jallepalli said, “Thank you, (EBRPD Police) Chief Filice for having us here, today to remember Maria Weidhofer and to be able to speak on her behalf. Pursuit of justice is a marathon not a sprint. We’re all standing here today because of our shared commitment to justice. It’s been 35 years since Maria was murdered on November 15, 1990. Since that day, her death and circumstances touched everyone, her family, the community and members of law enforcement. Everyone who worked on this case for 30-plus years was dedicated to solving this crime. They did so with shared determination that Maria’s death would not remain unsolved.”
“The partnership of this case between East Bay Regional Parks Police, the FBI, the District Attorney’s Cold Case Unit and the Contra Costa County Crime Lab was a reflection of that determination, using the latest technology and investigative techniques to obtain answers that could not have been obtained decades or even years ago,” he continued. “The pursuit of justice requires endurance, resilience and the willingness to go the distance even when the path ahead is long and uncertain,” Jallepalli stated. “While solving this case will never heal the wounds of Maria’s family caused by her murder we, from the District Attorney’s Office, are grateful to have been a part of that effort to bring these long-awaited answers to the community and more importantly, to her family.”

 Among 74 honored out of 429 in state
Among 74 honored out of 429 in state
SACRAMENTO—State Superintendent of Public Instruction Tony Thurmond announced today that 74 schools throughout the state were recognized as Model Continuation High Schools (MCHS) for 2025. These schools provide comprehensive services to at-risk youth through exemplary instructional strategies, flexible scheduling, and guidance and counseling services. Continuation schools provide a high school diploma program for students who have not graduated from high school, are required to attend school, and are at risk of not completing their education.
Four of those schools are located in Contra Costa County:
• Antioch Unified School District, Bidwell High School in Antioch
• Mount Diablo Unified School District, Olympic High School in Concord
• San Ramon Valley Unified School District, Del Amigo High in San Ramon
• West Contra Costa School District, Sylvester Greenwood Academy in Richmond
“Today, we celebrate 74 commendable schools for their tremendous efforts as alternative campuses of learning,” said Superintendent Thurmond. “The priority of our Model Continuation High Schools is to give students more than a diploma. The teachers and administrators aim to provide students with a student-centered approach that meets their diverse academic, social, and emotional needs and opportunities to explore options beyond high school, preparing students for the future whether they choose to pursue further education or join the workforce.”
Currently, there are 429 continuation high schools who serve close to 49,000 students throughout the state. MCHSs excel and provide exceptional opportunities for their students to pursue academic and social success.
The Model Continuation High School Recognition Program is a collaborative partnership between the California Department of Education (CDE) and the California Continuation Education Association Plus (CCEA Plus). Schools operate their own exemplary programs, but Model Continuation High School–recognized educators commit to supporting and mentoring their peers in other local educational agencies.
The 74 schools selected as Model Continuation High Schools retain their designation for three years. They will be recognized at the CCEA Plus 2025 State Conference in April. For more information on continuation education, please visit the CDE Continuation Education web page.

Through Parks California’s Route to Parks grant program, these funds will help more than 7,700 people create lasting memories at state parks in 2025.
 The 2025 grantees include programs from across the state, focused on providing experiences in parks through activities such as camping, backpacking by bike and recurring, single-day programs. Three projects with California Native American tribes: Fernandeño Tataviam Band of Mission Indians, Jamul Indian Village and the Mishewal Wappo will help increase access to their ancestral lands and cultivate collaboration and partnerships with park staff.

Three projects with California Native American tribes: Fernandeño Tataviam Band of Mission Indians, Jamul Indian Village and the Mishewal Wappo will help increase access to their ancestral lands and cultivate collaboration and partnerships with park staff.
For the 2025 grant cycle, we sought proposals that address the following criteria:
• Primarily provide transportation to/from California State Parks and beaches;
• Offer valuable recreational, environmental, cultural or historical learning experiences;
• Reach underrepresented communities who may face challenges getting to or enjoying parks, and/or lack opportunities to create meaningful connections to nature;
• Address parts of the state with the greatest transportation needs.
“The Route to Parks program highlights the power of partnerships in complementing California State Park’s efforts, bridging gaps to ensure memorable outdoor access for all,” said California State Parks Director Armando Quintero. “Partnering with Parks California expands our efforts in creating more opportunities for Californians to make lasting connections with the wonder of their state parks.”
Parks California’s Route to Parks grants program was launched in 2020 to reduce transportation barriers and help ensure that historically marginalized communities can visit and enjoy California’s world-class state parks. The program is made possible through a joint agreement between California State Parks and Parks California, and investments from private donors, including the PG&E Corporation Foundation and BMO.
“California’s state parks belong to all of us, yet too many communities face barriers to enjoying these incredible spaces,” said Parks California President and CEO Kindley Walsh Lawlor. “Through Route to Parks, we’re working alongside our partners to break down those barriers — ensuring that transportation, cost or other obstacles don’t stand in the way of people experiencing the joy, health benefits and sense of belonging that parks provide. My sincere appreciation to this year’s grantees who are leading the way in connecting communities to nature; we are honored to support their work.”
Grant awards average $37,675 and will fund transportation, logistics and park activities. Grantee recipients represent the diversity and reach of California’s state park system.

By Ted Asregadoo, PIO, Contra Costa District Attorney’s Office
The Bay Area Air District and the Contra Costa County District Attorney’s Office understand the community’s concerns following the February 1, 2025, fire at the Martinez Refining Company. (See related articles here, here, here and here)
The Air District has been evaluating the fire’s air quality impacts and has issued three notices of violation to MRC for violating Air District regulations. These notices of violation were issued for creating a public nuisance, for failing to operate equipment as permitted, and for excessive smoke and soot fallout. The Air District’s investigations are ongoing, and the agency will issue further notices of violation for any additional violations uncovered.
Additionally, the Air District and the District Attorney’s Office continue the joint civil enforcement action against MRC for previous violations at this refinery. The two agencies are working collaboratively to take a comprehensive approach to ensure MRC’s compliance with all air quality regulations. While we understand the public’s interest, the confidential nature of the process prevents us from commenting on the status of this enforcement action.

“This could have been much worse. We got lucky this time,” – County Health Officer Dr. Ori Tzvieli
By Contra Costa Health
The Martinez Refining Company (MRC), owned by PBF Energy, has told local health officials that chemicals and combustion byproducts from a recent fire at the refinery included chemicals that can cause cancer, as well as heart and lung disease.
Dr. Ori Tzvieli, the County’s health officer, said the community was fortunate that the wind blew most of the toxic smoke north of the refinery, away from populated areas.
“This could have been much worse,” Dr. Tzvieli said. “We got lucky this time. But our community shouldn’t have to rely on luck.”
Air-quality measurements taken by Contra Costa Health’s hazmat staff during the incident showed that concentrations of chemicals in the air during the event were mostly below the threshold considered dangerous. There was a short period when the smoke from the fire stayed closer to the ground and particulate matter immediately North of the refinery measured at a high level, but because that was not sustained over a long period it is not expected to have a significant health impact on most people. The Bay Area Air Quality Managment District (BAAQMD) also took air samples during the incident, which the health department will review after the results are available.
The blaze started at 1:30 p.m. on Feb. 1 as refinery workers prepared for a planned maintenance of a process unit that had been shut down earlier in the week. While opening equipment, hydrocarbon started to leak and ignited the fire, according to MRC’s 72-hour follow-up report to the County. Six refinery workers were evaluated by medical personnel and released.
The County initially issued a health advisory to residents in nearby Martinez, Pacheco and Clyde. Contra Costa Health later ordered a shelter-in-place to residents in Martinez north of the refinery when the smoke got closer to ground level. The shelter-in-place order was lifted later that night, although the health advisory remained in effect until the fire was completely put out on Feb. 4.
On Feb. 5, Contra Costa Health (CCH) sent MRC a letter asking the refinery to disclose what products were released or caught fire during the blaze.
In its response, MRC revealed that the following chemical products were involved: naphtha (petroleum), light thermal and light catalytic cracked; distillates (petroleum), light catalytic cracked; isobutane-rich C3-C4; diethanolamine; and distillates (petroleum), intermed cat cracked.
Combustion byproducts from the fire included particulate matter from the smoke, benzene, hydrogen sulfide, sulfur dioxide and xylene.
The combustion byproducts pose the greatest health concern. CCH will be working closely with a toxicologist to assess whether there may be any long-term health impacts, including potential impacts to soil and water.
MRC is scheduled to provide CCH a 30-day follow-up report in early March. The County is in the process of hiring a firm to do an independent root-cause analysis to determine why the accident happened and how it can be prevented from happening again.
“Like the community, I am concerned about the byproducts released during the fire and any health impacts they pose to residents,” said Contra Costa County Supervisor Shanelle Scales-Preston, whose district includes the area around the refinery. “I will work to ensure all reports and analyses done by or contracted by MRC, CCH, and the Air District are released fully and promptly. My top priority continues to be the health and safety of the community.”
“I want to thank all the first responders who bravely fought to contain the fire and monitored the incident for health impacts,” Scales-Preston added. “My goal for the future is that we don’t have accidents at the refinery that require first responders to get involved in the first place.”
The fire is the latest in a string of safety incidents at MRC over the past two-and-a-half years. In November 2022, the refinery accidentally released tons of toxic spent-catalyst dust in the surrounding community.

Connects Hwy 4 to Heidorn Ranch Road and Hillcrest Avenue in Antioch
By Allen D. Payton
The City of Brentwood announced on Monday, “The Sand Creek Road Extension is NOW OPEN! We’re thrilled to bring this new roadway to the community and hope it enhances your travels. Please drive safely and enjoy the new route!”
About the delay in the road’s opening two weeks after the ribbon cutting, Assistant City Manager Darin Gale said, “The extension is a unique project because it starts at an intersection that’s controlled by Caltrans and ends at an intersection that’s controlled by Antioch.”
“There were still some items that needed to be completed before we could open the road,” he shared, reiterating what City Manager Tim Ogden said during the ribbon cutting ceremony on Jan. 28. (See related article)
“We appreciate the partnership with those two agencies in getting the road open as quickly as possible” Gale added.
“Part of the intersection built by the developer in Antioch had not yet been approved by the City of Antioch,” he explained as one of the reasons for the delay.
Gale was asked about the timing of the opening and if it had anything to do with the new Costco opening nearby.
He responded, “The City of Brentwood was moving forward with the Sand Creek Road anyway. However, the road does provide a connection to Costco. While it was coincidental to the timing of the opening of Costco, it helped us with attracting the store to Brentwood.”
“We look forward to Sand Creek Road serving the Brentwood Innovation Center (located to the north) and bringing jobs to the residents of East County,” Gale stated.
The new section of the road now connects to the Antioch section at Heidorn Ranch Road, then to Hillcrest Avenue and west to the road that runs north adjacent to Dozier Libbey Medical High School in Antioch.
Gale also reiterated what Antioch Mayor Ron Bernal said at the ribbon cutting, as previously reported. He said, “Richland Communities over to the west of us, they’re going to be starting this year, I’m told, on their subdivision that’s going to build that final link between Sand Creek Road, where it terminates right now, and Deer Valley Road. So, that’s going to be able to get residents and folks over to Kaiser, which is important, getting people off of Deer Valley Road.”
Sand Creek Road will eventually connect to Dallas Ranch Road in Antioch, on the west side of Deer Valley Road and run through The Ranch 1,177-new home subdivision developed by Richland Communities and approved by the Antioch City Council in July 2020.
