Actor Jason Patric's Brother Struck and Killed By Bus in New Jersey

Jason Patric‘s brother was struck and killed by a bus this week in New Jersey … TMZ has confirmed.

Law enforcement sources tell TMZ … Jordan Miller — who’s a year younger than Jason — was walking across the street in Fort Lee Wednesday afternoon, when a NJ Transit bus barreled into him while making a left turn, according to a preliminary police account.

We’re told Jordan was rushed to a local hospital, where he was initially listed in serious condition, but then took a turn for the worse and was later pronounced dead.

Fort Lee PD detectives are investigating the circumstances surrounding the incident to determine if it was an accident or a crime. Jordan was a customer service rep at the Port Authority Bus Terminal in Midtown Manhattan. A Port Authority rep confirmed to us Jordan is, in fact, the sibling of Jason … who apparently was friendly with folks in the agency.

As you probably know, Jason is a big-time Hollywood actor with a laundry list of film credits — including “The Lost Boys,” “Sleepers,” “Geronimo: An American Legend,” “Your Friends & Neighbors,” “Narc,” “The Losers,” “The Alamo,” and “Speed 2: Cruise Control.” Jason has also appeared on some TV shows, such as “Entourage” and “Saturday Night Live” as host.

We reached out to Jason’s camp … they had no comment. Jordan was 56.
