Sonora, CA…In the afternoon on Sunday January 8th, a physical altercation occurred at an apartment on Chukar Circle in Sonora. The fight apparently stemmed due to using racial slurs. After the fight, several people left the apartment in a white SUV. Two of the occupants in the vehicle were identified as 20 year old Zachary Zimmerman and 19 year old Ethan Pomeroy both of Sonora. Witnesses reported that Zimmerman yelled that he would be, “Back with a blast.”

Later the same evening around 7:30 PM, Tuolumne County Sheriff’s Dispatch received a 911 call from the occupants at the apartment where the fight had taken place earlier in the day. The residents reported that someone had shot out the front window of their apartment. Deputies responded and were able to gather more information and determined that the window was shot with a shotgun.

During a briefing of the incident, Deputy Brandon Green recognized Zimmerman as being on probation and currently on a GPS ankle monitor. Deputy Green researched the history on Zimmerman’s ankle monitor and confirmed that he was at the location of the fight in the afternoon. It was also determined that Zimmerman left Chukar Circle and went to a residence in the 19000 block of Callahan Road in Sonora that belongs to the father of Ethon Pomeroy. Zimmerman then returned to Chukar Circle, at the time of the shooting.

On the morning of Tuesday, January 17th, Detectives served a search warrant at the home in the 19000 block of Callahan Road. During the search of that residence, Detectives located a shotgun with a sawed off stock as well as another disassembled firearm.
