Jackson Odell, an actor and aspiring singer best known for appearing in the ABC sitcom “The Goldbergs,” died Friday at age 20, according to the County of Los Angeles coroner’s office.

“The Odell family has lost our beloved son and brother,” Mr. Odell’s family said in a statement posted to his website. “He will always be a shining light and a brilliant, loving and talented soul. He had so much more to share.”

“We are now going to try to make sense of our immeasurable loss privately,” it added. “We will not be making any further statements.”

The coroner’s office said that the actor was found unresponsive on Friday in his room at a sober-living facility in the Tarzana neighborhood of Los Angeles, where he had been living. He had failed to attend a meeting that day. Sober living is typically an interim step between rehabilitation and regular life.
