Pat Tillman's Brother Arrested After Car Crashes into Post Office in California: Reports By Becca Longmire

The brother of late NFL star Pat Tillman has been arrested after a car crashed into a post office in San Jose, Calif., according to reports.

In the early hours of the morning on Sunday, July 20, the San Jose Fire Department (SJFD) responded to reports of a blaze “at the Almaden Valley Post Office on the 6500 block of Crown Blvd in south [San Jose],” per an Instagram post.

The fire department, which shared multiple photos of the blaze, stated, “Second alarm response with ~50 personnel on scene. Defensive operations were performed to prevent extension. No injuries reported. Cause is under investigation.”

Richard Tillman, 44, has since been booked into the Santa Clara County Jail on suspicion of arson, per ABC News.

NBC Bay Area reported that the suspect had told officers at the scene that he was the brother of Pat Tillman, and that he’d allegedly live-streamed the incident on social media, citing a source with knowledge of the investigation.

The Santa Clara County Sheriff’s Office’s online inmate records, which have been seen by PEOPLE and are accessible to the public, indicate that Richard Tillman was arrested on Sunday, with a court appearance scheduled for Wednesday, July 23, at 12 p.m. local time.

The U.S. Postal Inspection Service (USPIS) said in a statement, “Shortly after 3 a.m., the San Jose Fire and Police Departments responded to reports of a vehicle on fire in the box lobby area at the Almaden Valley Station Post Office. The fire was extinguished with no injuries,” per ABC News.

“The person in police custody is named Richard Tillman, who is reported to be the brother of the late NFL player and US Army soldier Patrick Tillman,” USPIS added, according to CNN.
