PORTLAND, Ore.—A federal grand jury in Portland has returned an indictment charging a Tigard, Oregon man with threatening a mass shooting at a local elementary school.

Brandon Richard Riess, 26, has been charged with transmitting a threat in interstate commerce.

According to court documents, on May 15, 2022, Riess submitted to a federal agency multiple electronic messages threatening a mass shooting at a Portland area elementary school. On May 16, 2022, law enforcement arrested Riess at his apartment in Tigard. Prior to his arrest, Riess admitted to sending the threatening messages and owning a pistol that was taken away several years earlier by his parents.

Riess made his initial appearance in federal court today before U.S. Magistrate Judge Youlee Yim You. He was arraigned, pleaded not guilty, and ordered detained pending a three-day jury trial scheduled to begin on August 16. 2022.

If convicted, Riess faces a maximum sentence of five years in federal prison, three years’ supervised release, and a fine of $250,000.

Riess also faces six counts of disorderly conduct in Washington County Circuit Court.

Administrators and parents of the affected elementary school have been notified of Riess’s arrest. No known active threat exists.

U.S. Attorney Scott Erik Asphaug of the District of Oregon made the announcement.

This case was investigated by the FBI with assistance from the Washington County Sheriff’s Office, Sherwood Police Department, and Washington County District Attorney’s Office. Assistant U.S. Attorney Natalie K. Wight is prosecuting the case.

An indictment is only an accusation of a crime, and a defendant is presumed innocent unless and until proven guilty.

Anyone with information about real or perceived threats of violence should call the FBI at (503) 224-4181 or submit a tip online at For immediate threats to life and safety, please call 9-1-1.
