A survivor of the 1999 Colombine shooting was found dead in his Colorado home at 37, local media reported Saturday.

Austin Eubanks had struggled with an opioid addiction since days after the mass shooting, which claimed the life of his best friend as they cowered together under a table in the library.

In the 20 years since, he had become a professional speaker on the topics of addiction, recovery and drug policy.

Family said in a statement that he “lost the battle with the very disease he fought so hard to help others face.”

Eubanks died in his home in Steamboat Springs either late Friday night or early Saturday morning, the Routt County Coroner said.

There was no sign of foul play, and an autopsy will be performed Monday, officials said.
