In an extensive Tuesday release, the FBI offered much more information on serial killer Israel Keyes' far-flung travels, following up on the initial Monday release of a timeline detailing his 15-year trail of murders, robberies and sexual assaults.
On Tuesday, the bureau provided five videos of hour-long interview sessions with Keyes it conducted last year before his December suicide, in an attempt to spur public recollection on his actions and the crimes in which he is implicated.
In an interview posted Tuesday by the FBI, Special Agent Jolene Goeden says Keyes had planned to keep killing people, until he was arrested in Texas in connection with the February death of Anchorage barista Samantha Koenig.
"Israel Keyes had no remorse at all," Goeden said. "He enjoyed what he did, he talked about enjoying what he did, he talked about, you know, had he not been caught, some of his future plans and what he would have done, which included continuing to do what he was doing, continuing to kidnap and murder people, so he had no remorse at all."
The bureau said it is making the information public in the hopes that someone will be able to provide insight into Keyes' alleged involvement in 11 suspected homicides, up from a previous estimate of eight, and possibly to find leads in other unsolved crimes.
Goeden says Keyes was evasive in interviews, but also quick to correct them when they had something wrong. Investigators came to believe that when he referred to killing less than 12 people, he meant 11 -- a hypothesis they tested in subsequent talks.
"There were several times where we just threw out statements like 'your 11 victims' and things like that and he didn’t correct us, so based on that and some additional things that he said, we believe the number is 11," Goeden said.
Before committing suicide in December 2012, Keyes admitted to raping and killing Koenig in February 2012, and to attempting to ransom her corpse. He is also suspected of the brutal murders of Vermont couple Bill and Lorraine Currier.
A statement from the FBI's Anchorage office suggests Keyes could have been involved in other unsolved homicides.
"We have a comprehensive timeline, we can identify where he's traveled to," said Deirdre Fike, the FBI agent in charge of the case, in an interview with Channel 2.
Among the revelations in Monday's timeline are explanations of Keyes’ methods, which he discussed with investigators before killing himself in jail.
Keyes did not know his victims prior to their abductions, he frequented prostitutes, and there was no apparent rhyme or reason behind any of the crimes, said Fike. He also traveled thousands of miles to plan and execute brutal attacks.
"Sometimes he would fly into one area, rent a car and drive a thousand miles to where the crime was actually committed, so there are some challenges in investigating crimes of that nature," Fike said.
According to Goeden, Keyes' meticulous nature extended to his approach to the interviews.
"I never got the sense that he accidentally told us something or got angry and riled up and something flew out of his mouth," Goeden said. "My sense was that he knew every time he came in kind of what he was going to give us that day."Anyone with more information on Keyes or his crimes is asked to call the bureau at 1-800-CALL-FBI.
