A 19-year-old Vallejo man is in custody following his arrest in connection with the June 18 robbery at the Macy’s in Walnut Creek’s Broadway Plaza. Walnut Creek Police identified Jammoni Simon as one of the suspects in the robbery. Patrol and Investigations worked together to identify the suspect and a warrant was subsequently authored for his arrest. Simon was taken into custody by the Contra Costa County Sheriff’s office on July 5, 2022. During his arrest, Simon was found to be in possession of a loaded firearm.
Walnut Creek Police Chief Jamie Knox said the arrest is a signal to others involved in that crime and to the public. “Walnut Creek Police Department puts the public safety of those who live, work, or visit here at the highest priority,” Knox said. “We will continue to actively pursue this case; Walnut Creek is not an open target for criminals.”
The case was presented to the District Attorney’s Office on July 8th and Simon remains in custody on the following charges:
PC 211, Robbery
PC 459, Burglary
PC 25850(a)(c)(6), Possession of a Loaded Firearm
Detectives continued to develop leads and determined Gerald Dial, a 20-year-old male from Vallejo, was involved and presented this case for review to the Contra Costa District Attorney’s Office. On February 28th, 2023, the Contra Costa District Attorney’s Office filed the following felony charges against Dial:

On March 23rd, 2023, WCPD Detectives located and arrested Dial on a warrant at the San Francisco Airport. Dial was booked into the Martinez Detention Facility. Dial is no longer in custody, as he posted bail.
