Blake Heron, best known for his starring role in the 1996 family film Shiloh, has died. He was 35.

The actor, whose death was confirmed to EW by the Los Angeles County Department of Medical Examiner-Coroner, was found unresponsive at his Los Angeles-area residence Friday morning. A cause of death has not yet been determined.

Born in Sherman Oaks, Calif., Heron made his big screen debut at 13 in the 1995 Disney film Tom and Huck. The next year, he had the biggest role of his career as the lead in Shiloh, where he played Marty Preston, a young boy who rescues a hunting dog from an abusive owner. As a child actor, he also starred in the TV movie Trilogy of Terror II and the WB sitcom Nick Freno: Licensed Teacher.

As an adult, Heron was featured in Mel Gibson’s We Were Soldiers and made guest appearances on ER, The Practice, Justified, and Criminal Minds.

Heron had a history of heroin use, per TMZ, which reported he recently checked out of rehab. He channeled his past addiction for a role in the recent Tribeca Film Festival entry A Thousand Junkies.

“It was easy to get into character, but it was also at certain points kind of rough, revisiting that frame of mind, and lifestyle,” Heron told Deadline in April. “The film portrays us — the way we used to be — pretty accurately, so to revisit that sometimes was a little bit of a bummer, but I had a blast doing the movie.”

His last role be alongside Kevin Dillon in the upcoming racing film Dirt.
