A suspected serial killer has killed for the last time.
Authorities say Israel Keyes, who was arrested and charged in the killing of an Alaskan barista, killed himself while in custody.
Before committing suicide on Sunday, Keyes confessed to at least seven other slayings, according to the FBI field office in Anchorage, Alaska, which on Monday asked for the public's help with tracing Keyes' travels over the years in the hopes of identifying any additional victims.
He crisscrossed the country, and authorities may never know how many he killed.
"Based upon investigation conducted following his arrest in March 2012, Israel Keyes is believed to have committed multiple kidnappings and murders across the country between 2001 and March 2012," the office said in a statement. "Keyes described significant planning and preparation for his murders, reflecting a meticulous and organized approach to his crimes."FULL STORY
