Before he killed himself, the 34-year-old Keyes, who often worked in construction, named two of his victims, Bill and Lorraine Currier, a middle-aged couple in Vermont that he killed in 2011. Their bodies have never been found.
Now, the FBI is hoping the public can help identify other victims.
Keyes is thought to have killed at least 11 people across the country from 2001 to 2012. The murders stopped with his arrest in Texas, one month after abducting and killing an 18-year-old woman in Anchorage. He confessed to several murders before committing suicide in prison. Police found one of Keyes’ victims, but ruled it an accident.
Keyes lived in Washington for a time and confessed to killing four people here, but we don’t know who they are and the FBI is interested in a 2008 trip he took to Seattle.
On Oct. 31, 2008, Keyes used Seattle as home base for several trips to other states during his six-day stay. He was known to have visited North Dakota and Arizona during that time and flew roundtrip from Seattle to Boston. On Nov. 5, 2008, he took a flight to Anchorage.
The FBI wants to hear from anyone who saw Keyes during that time to get an understanding of what he did during the trip.
During a jailhouse interview, Keyes explained why he wouldn’t give investigators the names of the victims, but the FBI does not believe Keyes was responsible for the murder of Mary Cooper and her daughter Susanna Stodden in 2006 on the Pinnacle Lake Trail in Snohomish County.
The FBI is working with local police departments around the country to connect any missing persons to Keyes by using his DNA.
