Authorities say they have confirmed that a man who committed suicide in an Alaska jail killed a Vermont couple missing since last year.

Officials said at a news conference in Vermont on Monday afternoon that 34-year-old Israel Keyes provided details about the abduction of Bill and Lorraine Currier that authorities had not released to the public.

Officials say he broke into the Currier's home, tied them up and forced them into their car. He then drove them to an abandoned house in Essex. Authorities say both the Curriers tried to escape. Keyes then shot Bill Currier with a gun he had stolen from the couple's home and sexually assaulted and strangled Lorraine Currier.

Their bodies have never been found.
