Police believe he may go to Kindred Transitional Care and Rehabilitation’s Tunnell Center at 1359 Pine St. where he received treatment for a stroke he recently suffered.

Brockett hasn’t taken his medication and suffers from mental health issues causing him to become enraged and combative at times, police said.

Brocket has been depressed since his partner of 15 years recently left him after the stroke.

Anyone with information on Brockett’s whereabouts is asked to call San Francisco police at (415) 553-1071 or Ana at (415) 440-6142.
