MARTINEZ — A Bay Area man who allegedly talked online about wanting to emulate the Poway synagogue shooter “except with a Nazi uniform on” is in county jail and facing three felony charges, after an investigation by the FBI and Concord police.

Concord resident Ross Anthony Farca, 23, was charged this week with making criminal threats, as well as manufacturing and possessing an assault weapon. The charges stem from comments Farca allegedly posted to his account on Steam, a popular video game platform.

Farca’s screen name was “Adolf Hitler (((6 Million))),” a reference to the number of Jewish people killed during the Holocaust. In posts to his Steam account, Farca allegedly expressed a desire to massacre Jewish people, livestream it to the internet, and then murder as many police officers as he could before they killed or captured him.

“I would probably get a body count of like 30 (Jews) and then like five police officers because I would also decide to fight to the death,” Farca said in one post, using a derogatory term to refer to Jewish people, according to court records. In other posts, he allegedly discussed picking a “better target than some random synagogue,” and referred to Jews as “subhumans.”

Farca also allegedly bragged about his ability to make a homemade assault rifle. When authorities searched his home in the 2100 block of Calgary Lane in Concord, that’s exactly what they found, along with 13 magazines, a three-foot Katana sword, camouflage clothes, ammunition, a hunting knife, and books about Hitler youth and Nazi life, according to police.

In other posts on Steam, Farca also reportedly wrote about being inspired by two 2019 mass shootings: the Christchurch mosque shootings in New Zealand, in March, and the Poway synagogue shooting in San Diego, a month later. He named both shooters and referred to the Christchurch shooter as a “hero,” authorities said.

Farca’s previous contacts with police include a 2011 incident when he was placed in a mental health hold after fighting with police who’d responded to a family dispute in his home. In 2015, a worker at the Regional Center of the East Bay, which assists people with developmental disabilities, told police she thought Farca fit the profile of a school shooter, according to court records.

Farca remains in custody in lieu of $125,000 bail, and pleaded not guilty at his arraignment hearing, prosecutors said.
