ANCHORAGE, Alaska (KTUU) -- Israel Keyes, the man accused with the kidnapping and resulting death of 18-year-old barista Samantha Koenig, was found dead Sunday morning, according to the Department of Corrections and Alaska State Troopers.
Keyes, 34, was awaiting a trial in March for the killing of Koenig, whose body was found in Matanuska Lake under the ice.
Karen Loeffler, the U.S. Attorney for Alaska, at a news conference Sunday afternoon said Keyes was found dead in his cell at the Anchorage Jail Sunday morning of an apparent suicide.
Troopers said "no foul play is suspected," and his body will be sent to the State Medical Examiner's office.
Now that he is dead, Loeffler said more questions about other crimes Keyes may have been involved with will be answered. FBI officials considered Keyes a serial killer and is linking him to deaths in other states, including four in Washington state, one in New York and the death of a Vermont couple.
"We've developed information that he was responsible for multiple additional victims. To our knowledge there are no other victims here in Alaska. They're all in the Lower 48," said FBI Special Agent Mary Rook.
"We do know he traveled extensively and he didn't always stay where he landed. He would land in one airport, rent a car and drive hundreds of miles."
Keyes confessed to killing Koenig after his arrest in March on federal access device charges, according to law enforcement.
