On May 12th, 2019, Concord Police Officers responded to Round 1 (185 Sun Valley Mall) for an armed robbery in progress. Two masked men forced two employees into a locked cash room at gunpoint where the employees’ hands were zip tied behind their backs and cash was stolen. One of the employees was able to free herself and called for help. Numerous officers responded, cleared the business and found the suspects had fled. It was determined the suspects gained access through a normally secured employee entrance.

Detectives from the Concord Police Department’s Major Crimes Unit began a two month investigation into this robbery. They uncovered a conspiracy involving Round 1 security guard Gary Dillahunty, who was working the night of and facilitated the robbery. Detectives also identified 37-year-old Vincent Timmons as one of the suspects who committed the robbery. Last week a search warrant was served at Timmons’ home in San Francisco. Evidence linking Timmons to the Round 1 robbery as well as an illegal assault weapon, a handgun, and a large quantity of cocaine was found. Timmons, who is on parole for kidnapping, was located at the home and arrested for robbery.

Yesterday, with the assistance of the United States Marshals, 43-year-old Dillahunty, who is on parole for assault with a deadly weapon, was located at a home in Vacaville. He was arrested on an outstanding arrest warrant for the Round 1 robbery as well as a warrant for violating his parole.

The Contra Costa District Attorney’s Office has charged both men with multiple felonies including robbery, conspiracy, and kidnapping. They both remain in custody at the Contra Costa County Jail.

The investigation into others involved with this robbery, including the second masked suspect continues. The Concord Police Department would like to thank our partners with the San Francisco Police Department and the US Marshal’s for their assistance in bringing both of these suspects safely into custody.

The security guards working at Round 1 at the time of this robbery were employed by an outside security contractor. This information is being shared with the California Bureau of Security and Investigative Services, a regulator of the private security industry.

Felony attempted murder charges filed against him

A nearly week-long investigation into a shooting at the Six Flags Hurricane Harbor shooting has ended in an arrest. (See related article)

On July 13th just before ‪5p.m., a man was shot in the parking lot of Six Flags Hurricane Harbor. Officers responded to the parking lot where they found a man suffering from a gunshot wound to his lower body. The victim was transported to a local hospital where he was treated for serious but non-life-threatening injuries.

With the help of victim interviews and surveillance videos, Concord Police Detectives identified 28-year-old Donald Sims of Oakland as the shooter. Sims already had a warrant issued for his arrest out of the Oakland Police Department for an assault that happened several weeks before the shooting in Concord. On Thursday July 18th, Sims was captured by U.S. Marshals in Sacramento and was transferred to Santa Rita Jail on the Oakland PD warrant.

Our investigation revealed Sims and the victim were involved in a minor dispute in the parking lot of the water park. The victim was sitting in his car when Sims unexpectedly pulled a handgun from his car and fired at the victim.

On Monday July 22nd, the Contra Costa County District Attorney’s Office filed felony attempted murder charges against Sims along with weapon enhancements for the shooting at Six Flags Hurricane Harbor. Additionally, Sims was charged by the Alameda County District Attorney’s Office with an unrelated assault with a firearm case out of Oakland. Sims remains in custody.

On Sunday, July 21, 2019, at approximately 12:24 A.M., Concord PD Officers were dispatched to a motorcycle vs. automobile collision that occurred near the intersection of Concord Blvd. and Lodato Way. A motorcyclist was traveling east on Concord Blvd. when he attempted to pass a Toyota Prius also traveling east on Concord Blvd. ahead of him. The motorcycle collided with the rear end of the Prius and the solo rider was ejected, landing in the westbound lane of Concord Blvd. A dark-colored pickup truck, traveling west on Concord Blvd., ran over the motorcyclist while he was laying in the roadway. The driver of the truck continued west on Concord Blvd. and was not located. The driver of the Prius remained on scene and was cooperative with the investigation.

Due to injuries he sustained, the motorcyclist was pronounced deceased at the scene by Emergency Medical Personnel. His identity is not being released pending notification of next of kin.

The collision is still under investigation. Officers are attempting to identify and locate the driver of the pickup truck that left the scene.

Concord Blvd., between Ayers Road and Kirker Pass Road, was closed for approximately three hours for the investigation. No further details are being released at this time.

Anyone who may have witnessed the collision or who has any information on this case is asked to contact Traffic Officer Derrick King at the Concord Police Department, 925-671-5880.

Not on our Watch! Patrol officers from the Graves 1 team of the Concord PD responded to a silent alarm/probable burglary in-progress in the 1300 block of Galaxy Way on Wed., June 26 at 4:07 AM. Officers arrived in less than one minute and saw two vehicles fleeing. Officers tried to stop both vehicles and dual pursuits were initiated when both vehicles fled from pursuing officers onto Commerce Ave, across Concord Ave, then proceeding the wrong way up the southbound HYW 242 on-ramp. Officers stopped their pursuit(s) for safety reasons. A few moments later officers located one of the vehicles, a large RV, driving south on s/b HWY 242.

Officers pursued the RV for approximately 8-10 miles until the RV once again drove the wrong way up the southbound HWY 242 off-ramp at Solano Way, where CPD Officers terminated their pursuit. With help from citizen callers, the RV was located again, this time travelling west on the shoulder of eastbound HWY 4.

The driver, 34-year-old Jessica Tomsky (born 3/26/1985), was arrested for several counts of fleeing police officers, commercial burglary and possession of stolen property. There was stolen property from the commercial burglary she just fled from and stolen property from other commercial burglaries from Concord and other jurisdictions.

The Graves 1 team would like to thank the caller(s) who took the time to call 9-1-1 and update us on the location of the RV. Without help from our citizen’s our job would be much more difficult.
