Investigators are now connecting Alaskan serial killer who committed suicide last December, Israel Keyes, to a total of 11 murders throughout the country.

On Monday the FBI released a timeline of his crimes since 1997, when he abducted a teenage girl from Oregon. When Keyes was released from the Army in 2001, he moved to Washington where he committed his first murder.

Keyes’ next move was to Anchorage, Alaska in 2007, but he still traveled a lot between states while living there. According to USA Today, before his suicide he admitted to killing eight people from all around the country, robbing several banks, and breaking into almost 30 homes. He also told investigators that he murdered them all in less than 10 states, but wouldn’t admit all the locations.

The only victims that Keyes specifically named to investigators were Bill and Lorraine Currier from Essex, Vt., and 18-year-old Samantha Koenig, although he did admit to killing an unidentified couple in Washington sometime between 2001-2005 and killing two more people in 2005-2006 and disposing of one of the bodies in Crescent Lake, Washington.

Koenig, 18, was taken from a coffee stand where she worked in Anchorage, Alaska in Feb. 2012. Keyes was arrested for the crime six weeks later in Lufkin, Texas because he used her debit card there. Her body was found in a frozen lake three weeks later.

Keyes was awaiting trial for her rape and murder when he killed himself in jail nine months after his arrest. CNN reports that he committed suicide by slitting one of his wrists and strangling himself with his bed sheet.

Since Keyes was known to travel to other countries throughout his crime spree, investigators are now looking into his possible connection with international murders.
