Concord: Man Arrested After Making Online Threats in Chatroom

According to police, the comments consisted of threats against Jewish people and to commit a mass shooting at a synagogue, threats to shoot law enforcement and claims to possess an assault rifle. There were no specific locations included in the threats.

Through the investigation, police identified Farca as a suspect after determining the threats came from an address in Concord.

Police say records showed that Farca had legally purchased an incomplete AR-15 rifle frame earlier this year.

On June 10th, an arrest warrant was issued for Farca as well as a search warrant for his house. The warrants were served and Farca was arrested at his home without incident. Inside his home, an illegal AR-15 semi-automatic rifle was found which had been constructed from the same legally purchased frame. Several high capacity magazines were also found but no rifle ammunition was located. Additionally, detectives located Nazi literature, camouflage clothing and a sword.

Farca was arrested for and ultimately charged by the Contra Costa District Attorney’s Office with making criminal threats, possession of an illegal assault rifle and manufacturing an assault rifle. Detectives also obtained an emergency Gun Violence Restraining Order against Farca to prevent him from legally purchasing firearms.

Farca remains in custody at the Contra Costa County Jail.

Police added that they are only aware of threats made by Farca due to a cyber-tip. No detailed plans to commit acts of violence have been located.
