Alaska Suspect Linked to Vermont Killing, 5 Others Israel Keyes, in jail for the killing of an Alaska barista, gradually began confessing to investigators that he had killed others: a couple in Vermont, four people in Washington state, someone in New York. But he was slow to come forward with details, warning investigators he would stop talking if his name was released publicly. "He was very, very, very sensitive to his reputation, as odd at that sounds," Anchorage Police Chief Mark Mew said. We had to keep things extra quiet in order to keep him talking with us. Keyes committed suicide in an Alaska jailhouse Sunday, leaving behind an incomplete picture of a loner who traveled the country for more than a decade, picking victims at random and methodically killing them. Officials believe there are more victims in other states, but they may never know who they are. They also did not say whether he left a note. "We're going to continue to run down leads and continue our efforts to identify his victims so we can bring some closure to the families," said Mary Rook, the FBI supervisor in Alaska. While under arrest in connection with the disappearance of 18-year-old barista Samantha Koenig, Keyes confessed to the deaths of Bill and Lorraine Currier, of Essex, Vt., who disappeared in June 2011, authorities said. Keyes confessed to other killings without identifying the victims or saying where their remains were located.

In interviews with investigators, Keyes detailed extensive planning, including burying caches of weapons at various points across the United States. The FBI says it recovered weapons and items used to dispose of bodies from hiding places just north of Anchorage and Blakes Falls Reservoir in New York. Keyes told investigators he scoped out potential victims at remote locations including campgrounds and cemeteries. He said few of his earlier cases received media attention until the Currier case, telling investigators that one victim had been found but incorrectly labeled as accidental. The FBI says it does not have a name or location in this case. Keyes also told authorities he robbed several banks to pay for his travel, using money he made as a general contractor as well. "There's no indication that he was lying," FBI spokesman Eric Gonzalez said, adding that Keyes' DNA has been put in an FBI database available for other law enforcement agencies to use in their own investigations. Also on Monday, officials at a news conference in Vermont said Keyes described details of the Curriers killings that had not been released publicly. Authorities said Keyes flew from Alaska to Chicago, then drove to Vermont and picked the Curriers, a couple in their 50s. He broke into their home and, in their bedroom, Keyes told police, he bound them with zip ties, forced them into their car and drove them to an abandoned house, where he shot Bill Currier with a gun he brought from Alaska, and then sexually assaulted and strangled Lorraine Currier. Keyes told investigators he chose the Curriers' home because it had an attached garage, no evidence of children or a dog, and the style of the house clued him in to the probable location of the master bedroom.
