A man suspected in four Arizona killings over the last few days fatally shot himself in a hotel as SWAT team members closed in, police said Monday. The man was identified as Dwight Lamon Jones. Scottsdale and Phoenix police officers had tracked the suspect to an Extended Stay hotel, authorities said. As guests were being evacuated, officers heard multiple gunshots from inside the man's room. He is believed to have killed four people in a 30-hour span.
