A man who police say was responsible for killing two homeless men and critically injuring two others was arrested Thursday.
Anthony Alexander Padgett, 36, acted alone in the series of attacks that started early Sunday morning, San Diego homicide Capt. David Nisleit said during a Thursday evening news conference. He declined to disclose a motive for the attacks.
The arrest came after police received tips from the public based on grainy pictures and surveillance footage of the suspect.
Police also served search warrants at several undisclosed locations and checked trolleys and bus stops because they believed the suspect was using public transit to get around.
