The brother of celebrated NFL player and Afghanistan war veteran Pat Tillman was arrested on suspicion of arson in San Jose, in a bizarre car crash into a post office that authorities suspect was intentional, and apparently was livestreamed.

A very strange incident happened in the wee hours of Sunday morning in San Jose, as NBC Bay Area reports that a car crashed into a San Jose post office, and the whole building went up in flames. The crash occurred just before 3 am Sunday at the post office on Crown Boulevard near the Almaden Expressway, and it took some 50 firefighters about 90 minutes to put out the blaze. Quite oddly, someone also graffitied the words “Viva La Me” onto the post office building before the fire, and authorities believe the driver of the car rammed into the post office intentionally.

It gets stranger. A follow-up report from NBC Bay Area reveals that the driver was taken into custody, and the report identifies the driver as 44-year-old Richard Tillman of San Jose. According to NBC Bay Area, that man “told officers on the scene he is Pat Tillman’s brother, and that he live-streamed the event on a social media platform."

KTVU spoke with US Postal Inspector Matthew Norfleet, whose agency has taken over the investigation. "We’re definitely investigating it as possibly an intentional act, so driving the vehicle into the building and then starting the fire can’t be ruled out as having been done on purpose," he told that station. As far as whether the suspect really is the brother of former NFL player Pat Tillman, Norfleet said, "We’re hearing the same report you have, but we have not confirmed that through our investigation."

Update: The Chronicle is now reporting that Richard Tillman's Youtube channel has been taken down, and that his family details a recent "unraveling" and descent into mental illness. Tillman had reportedly posted an 11-minute YouTube video just days ago vowing to “take down the system,” in which he referred to himself as "Yeshua" (the Hebrew word for Jesus), and said “As far as the next phase of the game, I know what needs to be done.” The Chron also details a number of Richard Tillman's misdemeanor arrests, and his "legal trouble, mental health issues and isolation from friends and family in recent years." That paper adds that a family member urged him to get psychiatric help, and he wrote back to that person “I’m here to end you…And all your worthless friends.”

NBC Bay Area also has the Monday afternoon news that Tillman's family has released a statement. ""Our family is aware that my brother Richard has been arrested. First and foremost, we are relieved that no one was physically harmed," the statement says. "To be clear, it’s no secret that Richard has been battling severe mental health issues for many years. He has been livestreaming, what I’ll call, his altered self on social media for anyone to witness. Unfortunately, securing the proper care and support for him has proven incredibly difficult - or rather, impossible. As a result, none of this is as shocking as it should be."

The older brother Pat Tillman, of course, was the star Arizona Cardinals defensive back who famously quit football and enlisted in the US Army not long after the September 11 attacks of 2001. Tillman was killed in Afghanistan in 2004, and the Department of Defense was accused of hiding the fact that Tillman was killed by friendly fire until long after his memorial services were over, allegedly hoping to avoid bad publicity.

Authorities say that a box of the younger Richard Tillman’s belongings was found at the scene, and contained a black and white photo of Pat Tillman in a football uniform.

There were no injuries in the incident, but Richard Tillman was booked on arson charges and is being held on $60,000 bail at Santa Clara County Jail. His next court appearance is scheduled for Wednesday.

And again, authorities are saying Tillman may have livestreamed the event. "It’s been reported to us that this person has been broadcasting on a video channel, so there may be video broadcasts related to this event," Norfleet told KTVU.

So that’s unusual, as is the fact that someone oddly spray-painted the words “Vive La Me” on the post office sometime before this fiery crash. "Those markings were not on the building yesterday,” Norfleet also pointed out to KTVU. “What their connection is to the fire and crash is so far unexplained. I cannot think of a reason why that would make sense, but that’s one of the things we’re looking into.”

Though for San Jose residents, the more urgent matter is what to do if you had mail or a post office box at that particular post office. Unsurprisingly, that Alamaden/Crown Boulevard post office that burned will be temporarily closed for the foreseeable future. Its mail operations will be moved to the Willow Glen Post Office at 1750 Meridian Avenue, and those with Almaden PO boxes will be able to retrieve their mail at the Willow Glen location starting Tuesday, and will need to provide photo ID.
