'Shiloh' star Blake Heron has died at age 35

Blake Heron, the child actor who starred in 1996's "Shiloh," has died at age 35.

Heron's cause of death has not been confirmed, but he had allegedly been battling the flu for several days. Paramedics found flu prescriptions in his home.

Although EMTs on the scene did not find any illegal drugs, sources confirmed to TMZ that Heron had struggled with heroin and recently got out of rehab. Earlier this year, Blake played a character of his own real name in a "A Thousand Junkies," movie about heroin addicts that screened at Tribeca Film Festival.

Heron's girlfriend went to his Los Angeles home on Friday morning, where she discovered him already dead.

A California native, Heron first appeared on-screen in Disney's "Tom and Huck" in 1995. A year later, he played the leading role in "Shiloh," the beloved story of a boy and his dog. In the early 2000s, he continued appearing on TV shows but largely stepped away from the spotlight.

Heron often posted photos of himself with his girlfriend. According to his Instagram profile, the two just recently returned from a trip to Paris. Those photos, and more from Heron's life, are in the slideshow above.
