San Diego police believe they have found the man behind a series of attacks on homeless men across the city that left two dead and two severely injured.

Thirty-six-year-old Anthony Padgett was booked Thursday night on suspicion of murder and attempted murder in the attacks on mostly sleeping men, some of whom were set on fire, police said.

Police Capt. David Nisleit says a tip led investigators to Padgett, who was born in the suburb of Chula Vista and was arrested there. Nisleit gave no further details on the man or the tip that led to him.

Nisleit said the investigation was in its "very early stages." He said authorities hadn't determined if the suspect was homeless himself but acknowledged that investigators searched homeless camps in Chula Vista.
