Chase was recently captured on a viral video in which he was seen living on the streets of Riverside.
"I reached out to some friends of mine and we have a bed for him at a detox, and we have a place for him to go and get long-term treatment," Weiss said in a video. "All we need to do now is find him. I'm not in Los Angeles or I would go look for him myself."
Weiss says he struggled with sobriety himself and empathizes with Chase, but says "recovery is possible."
