Night Stalker, aka Richard Ramirez, was a convicted serial killer in California. The 'Night Stalker' died in prison, awaiting execution.
Richard Ramirez, the notorious serial killer known as the "Night Stalker," died early Friday in a hospital, a state official said.
Ramirez, 53, "passed away this morning," San Quentin State Prison spokesman Lt. Sam Robinson told The Associated Press. No other details were released.
The Department of Corrections and Rehabilitation said Ramirez died of "natural causes." He had been housed on death row for decades and was awaiting execution, even though it has been years since anyone has been put to death in California.
Ramirez had been taken from death row to Marin General Hospital.
Ramirez was convicted of 13 murders that terrorized Southern California in 1984 and 1985, and was sentenced to death.
Satanic symbols were left at murder scenes and some victims were forced to "swear to Satan" by the killer, who entered homes through unlocked windows and doors.
Ramirez was captured and beaten in 1985 by residents of an East Los Angeles neighborhood while attempting a carjacking.
