Martinez, California – A Walnut Creek man was sentenced today in Contra Costa County Superior Court after entering guilty pleas to felony charges of sexual abuse of a minor and aggravated possession of child sexual abuse material.
28-year-old Marc Alexander Simon (born 12/25/96) was sentenced by the Honorable Charles Burch on June 26th, 2025, to six years and eight months in state prison. Simon was further ordered to register for life as a sex offender upon his release from custody.
The offenses for which Simon was sentenced occurred on April 11, 2024, when Simon followed a child into a restroom at the Walnut Creek Library and sexually abused the minor. The child reported the incident to an adult, who contacted the Walnut Creek Police Department.
Walnut Creek Police detectives used security cameras to quickly identify Simon’s vehicle as he left the scene. Police tracked him to another location in Walnut Creek, where he was arrested and booked into the Martinez Detention Facility. An iPhone seized during his arrest was forensically examined, revealing hundreds of images and videos of child sexual abuse material.
The transient man was arrested for lewd acts upon a child and attempted kidnapping. Simon has been in custody since his arrest and will begin to serve his sentence immediately. (See related article)
District Attorney Diana Becton said: “The swift investigative work by Walnut Creek Police and our Internet Crimes Against Children Task Force was crucial in holding the defendant accountable. This case demonstrates our unwavering commitment to protecting children in our communities from those who prey on them.”
Deputy District Attorney Ashley Torres from the Sexual Assault Unit prosecuted the case. The Walnut Creek Police Department Investigations Unit led the investigation with the assistance of the Contra Costa County Internet Crimes Against Children Task Force.

By Jimmy Lee, Director of Public Affairs, Office of the Contra Costa County Sheriff
The Contra Costa County Sheriff’s Office arrested two suspects after a reckless boating incident at Discovery Bay Marina on Sunday, June 22, 2025, that was widely shared on social media.
Deputy Sheriffs from the Marine Services Unit launched an investigation after multiple witnesses reported a Malibu ski boat chasing a personal watercraft (PWC) through the marina at high speeds. Deputies identified two operators during the incident, 33-year-old Erick Garcia and 34-year-old Danny Garcia, both from Oakley, who were seen operating the boat recklessly. The ski boat was later found abandoned in Stockton.
Erick Garcia was detained yesterday during a traffic stop in Oakley. With assistance from detectives in the Sheriff’s Office Investigations Division, Marine Patrol Deputies served a search warrant at Danny’s home in Oakley, leading to his arrest.
Both Danny and Erick Garcia were booked into the Martinez Detention Facility on identical charges:
- Assault with a Deadly Weapon (not a firearm) – 2 counts
- Criminal Threats – 1 count
- Vandalism – 2 counts
Each were being held in lieu of $95,000 bail. According to the Contra Costa Sheriff’s Office, Danny bonded out of custody today at 4:27 PM. However, as of Wednesday, June 25, at 4:42 PM, Erick was still in custody.
According to localcrimenews.com, Erick was arrested on May 3 this year by the Contra Costa County Sheriff’s Department for assault with any means of force likely to produce great bodily injury. He was also arrested on Sept. 5, 2024, by Contra Costa CHP for threats of violence. Danny was also arrested on May 3 this year, but by Walnut Creek Police, for being intoxicated in public and resisting a peace officer with injury.

The Contra Costa Water District Canal Replacement Project includes 20 miles of the waterway. Photo: CCWD
Lake Shasta is source of all water, Los Vaqueros Reservoir will not be expanded, CoCoTax members learn
By Allen D. Payton
During the Contra Costa Taxpayers Association Members and Leaders monthly luncheon in May, Contra Costa Water District Board President, Ernesto Avila provided an update on the district’s current work and plans. They include repairing 20 of the 48-mile canal at a cost of $1 billion, keeping water rates as low as possible and expanding service to keep up with growth.
The district includes the Central County cities and communities of Martinez, Pleasant Hill, Concord, Clayton, Pacheco, Clyde, Port Costa and portions of Walnut Creek, and in East County, the cities and communities of Pittsburg, Antioch, Oakley, Bay Point, and portions of Brentwood.

Half of the district’s water is provided to treated water customers and the other half to raw water customers, Avila stated and then spoke about ensuring adequate “water supply during disasters such as fire and earthquake emergencies.”
“When PG&E outages occur all of our tanks go full,” he shared. “Water only stays sweet for six to seven days to meet the water quality requirements of the state.”
“Lake Shasta is where we get all of our water from through the Central Valley Project,” he continued. “It’s currently 94% full.”
The district owns Los Vaqueros Reservoir for storage, which is currently 93% full. But “we can’t just draw water whenever we want,” Avila stated. “All of our intakes are screened to protect fish.”
“We are out of our drought,” Avila added. However, “during the drought there were no constraints on water supply for development and growth.”
Canal Replacement Program
There have been “landslides on the west side of the canal and repairs can cost millions,” he stated and spoke of the district’s “Canal Replacement Program” which will cost “$1 billion”.
“Nobody likes to raise rates,” Avila continued. “We’ve replaced four miles, so far and have 16 miles to go. It will be a pipeline”
Asked what happens to the pipe during an earthquake he said, “If it’s an older pipe, it will probably crack. We’re looking at a very ductile pipe that can move easily.”
Asked if there will be solar panels over the canl

Water Supply
Avila then spoke about providing enough water to meet the demands of residential growth including “redevelopment of the Concord Naval Weapons station” where “15,000 homes” are projected to be built.
“Ten percent of the district’s water is provided through recycling,” he stated. “We want to bump that up to fifteen percent.”
Budget & Water Costs to Users
“Energy costs have been the greatest increases from 2020 to 2024, medical coverage is second greatest,” he shared. Those are followed by “pension and OPEB (other post employee benefit) liabilities.”
“The average customer spends about $3.00 per day for water,” Avila stated. “The cost is 1.3 cents per gallon per day.”
He compared that to EBMUD rates which are at 2.0 cents per gallon.
According to the slide show from his presentation, costs to the district for water production include the following:
INVESTMENTS IN INFRASTRUCTURE – Pipeline Renewal, Canal Replacement, Water Treatment Plant Upgrades;
PURCHASED WATER
WATER SUPPLY AND RESOURCE PROTECTION – Water Supply Planning, Watershed Management, Recreation;
SYSTEM OPERATIONS & MAINTENANCE – Water Treatment, Water Delivery, Leak Inspection and Repair;
ADMINISTRATION – Human Resources, Safety, Accounting and Payroll;
CUSTOMER CARE – Customer Service, Billing, Water Efficiency Support, and Public Affairs; and
COMMUNITY EDUCATION AND WORKFORCE DEVELOPMENT K-12 Water Education and Field Trips, and Internships.
The district as an AAA Bond Rating which keeps interest costs on bonds down, Avila shared.
He was then asked about “money going to DEI programs. I this something you should be doing anymore?” Avila responded, “there are three employees dedicated to it. There are 317 employees which is 30-40% of the budget We have one person in Human Resources dedicated to it. We have a $200 million per year budget. Not even one percent is dedicated to it.”
“It’s about trying to enhance the culture for our employees to work together better,” he added. “We review it every six months. Our Master Plan is on the website.”
Asked about “EPA clean water requirements getting tougher each year” Avila spoke about “unfunded mandates we have to comply with. We work with various associations and collaborate on a national level as regulations are mostly at the federal level.”
“Our biggest concern is the issue of diminishing return on conservation,” he explained. “During the drought, people in our area reduced use by 25 percent while Southern California only reduced 2-3 percent.”
According to the chart in Avila’s presentation total water use has actually decreased over the past 17 years even though the population has significantly increased.
No Los Vaqueros Capacity Increase Due to Too Much Cost and Regulation, Offline for Too Long
Asked about increasing capacity at Los Vaqueros, Avila said, “The district spent $10 million on raising the…reservoir, for a cost/benefit analysis funded by the state. It was over subscribed with more customer demand than supply, 250,000 versus 120,000 acre feet.”
“But with so many constraints on pumping water into the reservoir, demand dropped to 50,000 acre feet then to zero,” he continued. “The cost increase with inflation went from $800 million to $1.6 billion, mainly from more material and labor cost increases, plus, engineering costs.”
Finally, Avila shared, “Los Vaqueros Reservoir would have had to be offline for six to seven years. It just wasn’t viable. They knew that, going in. The issue was negotiating supply from EBMUD and others” who “couldn’t guarantee any water.”
He also spoke about future supply including the proposed offstream Sites Reservoir project west of Colusa in the Sacramento Valley.
“In California, for every one million acre-feet of storage, there is eight to nine acre-feet of surface storage,” Avila stated.
Finally, in response to a question, he said, “Water from a canal behind a house is not grandfathered in if the home is sold.”
