Two arrested in armed robbery of Round 1 video arcade in Concord

By Concord Police Department

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.
