Prior to that, he lived in Washington state, where he confessed to killing four people, the FBI said. He is likewise alleged to have admitted to killing another person, somewhere on the East Coast, in 2009. The identities of those five victims were not released.
Finally, Keyes was accused and charged in the death of 18-year-old Samantha Koenig, the Alaskan barista. She was last seen on February 1 being led away by a man from the parking lot of the coffee stand where she worked. Her body was found in a lake north of Anchorage.
Authorities in Anchorage released a chilling account of the killing of Koenig in part to "help investigations of other murders committed by Israel Keyes."
Keyes had planned to commit a kidnapping at Koenig's coffee stand even though he did not know her, according to the joint statement by local and federal authorities in Alaska.
He approached near closing time on February 1, wearing a mask and ordered coffee. After Koenig made the coffee, Keyes brandished a gun forced himself into the coffee stand and bound the 18-year-old woman with zip ties. She tried to escape, was unsuccessful and he took her to his truck.
"Keyes drove around town, explaining to Samantha that this was a kidnapping for ransom," the statement said.
He killed her at his home, hid the body in a shed and then went on a cruise he had been planning.
He returned on February 17.
"He went into the shed and retrieved Samantha's body, taking steps to make it appear that she was still alive, and took a Polaroid picture of her tied up," the statement said.
He sent the picture to girl's family members using her cell phone. He demanded $30,000 be sent to an account associated with an ATM card he had stolen from her.
