LOS ANGELES -- Police have arrested a suspect in the stabbings of three Los Angeles-area homeless people in recent weeks, a man they say goes by a name signed on "death warrants" found with the wounded victims.

Officer Norma Eisenman says Courtney Anthony Robinson called 911 Friday and confessed to the crimes. Officers found Robinson on a Hollywood street corner and took him into custody without incident.

He is being held on half-million dollars bail.

Police previously described him as a possibly homeless man from Santa Barbara who also goes by David Ben Keyes, a name written on notes left at all three stabbing scenes that the writer called "death warrants."

One victim in Santa Monica and two in Los Angeles were stabbed in the back as they slept. The three victims, all in their 50s, survived.
