Methods -

After breaking into the homes of his victims, the Golden State Killer would allegedly bind the hands and feet of the boyfriend or husband and pile dishes on his back. He would proceed to rape the woman and threaten to kill both of them if the dishes tumbled.

Nickname - Before writer Michelle McNamara coined the nickname Golden State Killer, police called the man by the acronyms EARS and ONS, which stood for East Area Rapist and Original Night Stalker.

Voice recording - The killer would also call his victims to terrorize them before breaking in to their homes and raping and murdering them. In late 1977, an unknown man called 911 in the Sacramento area claiming he was the East Area Rapist, as he was known at the time.

Voice recording - Following the 911 call, police tapped the phone of a victim who had received a menacing call in January 1978. Police were able to tap a later call in which a man was recorded breathing deeply before repeatedly whispering, "Gonna kill you."

1978: He turns to murder - On February 2, 1978, the crimes escalated into full-on murder when the Golden State Killer killed U.S. Air Force Sgt. Brian Maggiore and his wife Katie while they were walking their dog in Rancho Cordova, Sacramento County. Many decades later, this crime would ultimately be his undoing: he was charged with two counts of murder for the deaths of the Maggiores, after new DNA evidence was found linking him to the crime.

1978 - After the murders, the killer apparently moved on from Sacramento and continued his crime spree in the East Bay area of Northern California. That year, he committed at least 15 crimes, according to KTLA.

Premeditation - The killer would often break into his victims’ homes before the actual crime to get a sense of the layout. He would study photographs and learn the victims’ family members’ names to frighten them as he attacked.
