Milwaukie resident arrested over terrorism threat in California
A resident of Milwaukie was arrested in Oregon City in connection with a threat of terrorism allegedly made in Riverside County, California.
Tarence Michael Thomas, 25, was arrested Feb. 28 on a warrant from the Riverside County Superior Court on the charge of conspiracy to commit murder. With the assistance of local authorities, investigators located Thomas in the area of a known associate's residence in Oregon City.
The investigation began Feb. 19, when the Riverside County Sheriff's Department received information about a series of threats made on social media. An investigation was immediately initiated regarding Jacob Ryan McBain posting comments on his Facebook page that he intended on shooting people at a local college campus.
After the arrest of McBain, information was developed pointing to an additional suspect and co-conspirator. Following up on the investigative leads, investigators identified the second suspect as Thomas, a resident of Milwaukie.
Officials from the Clackamas County Sheriff's Office, Clackamas County Inter-Agency Task Force (CCITF), FBI-Portland Office, FBI Joint Terrorism Task Force and Oregon City Police Department assisted in arresting Thomas.
When arresting Norco resident McBain, 27, deputies recovered a loaded AR-15, two loaded handguns and a large amount of ammunition from McBain's bedroom. He was arrested without incident on charges of making terrorist threats and being a felon in possession of a firearm.
Local school district and college officials were notified of the investigation, even though there was no school in session during the national holiday.
Anyone with any information pertaining to this investigation is encouraged to call Deputy Robertson of the Norco Sheriff's Office at 951-270-5673.
