LOS ANGELES — Richard Ramirez, the demonic serial killer known as the Night Stalker who left satanic signs at murder scenes and mutilated victims' bodies during a reign of terror in the 1980s, died early Friday in a hospital, a prison official said.
Ramirez, 53, had been taken from San Quentin's death row to a hospital where authorities said he died of liver failure. Prison officials said they could not release further details on the cause of death, citing federal patient privacy laws.
