PORT ANGELES, Wash. -- The FBI has received about 100 phone tips since asking the public for information about late Alaska serial killer Israel Keyes.
But FBI special agent Jolene Goeden of Anchorage said this week that none of those calls has connected Keyes to missing people on the Olympic Peninsula in Washington state, where he lived from 2001 to 2007.
"The majority of phone calls were from people who knew him and interacted with him, who would give information about the types of things he did, activity he was involved in," Goeden told the Peninsula Daily News.
Once a self-employed carpenter living in Anchorage, Keyes is thought to have killed 11 people across the United States from 2001 to 2012. Keyes burglarized 20 to 30 homes across the country and robbed several banks during that time period to fund his killing spree, according to the FBI.
Keyes committed suicide in an Anchorage jail in 2012 while awaiting a federal trial in the rape and strangulation murder of his last known victim, Samantha Koenig. Keyes abducted the 18-year-old from a coffee hut in Midtown Anchorage the night of Feb. 1, 2012, and strangled her in a shed outside his girlfriend's house in West Anchorage, where he lived, according to police and federal prosecutors. Koenig's dismembered body was pulled from a lake north of Anchorage two months after she went missing.
Goeden said this week that FBI agents also are investigating tips they received on missing people elsewhere in the Pacific Northwest.
"They are cases we're not able to rule him out of, but we can't rule him into, either," Goeden said.
Keyes told investigators he murdered his victims in fewer than 10 states but did not disclose all the locations or the victims' identities.
"In a series of interviews with law enforcement, Keyes described significant planning and preparation for his murders, reflecting a meticulous and organized approach to his crimes," the FBI said in its August appeal for the public's help. "Investigators believe Keyes did not know any of his victims prior to their abductions."
He is thought to have killed another person in Texas following the Koenig murder.
While in Texas, Keyes made repeated bank withdrawals using a debit card he stole from Koenig. Authorities tracked him down and arrested him there in March 2012, and federal agents extradited Keyes back to Anchorage. Keyes told investigators that prior to killing Koenig, he had slain a couple in Vermont -- Bill and Lorraine Currier -- in June 2011.
Keyes also talked about committing other prior abductions and murders, offering varying degrees of detail about each, but the investigators were never able to determine the names of the victims in those cases. He once said he was keeping as many details as possible out of the media so his daughter wouldn't be able to find any information up on the Internet or his mother wouldn't have a heart attack reading what he did.
Goeden said two agents in the FBI's Seattle office have been assigned to the case to investigate any leads in the state.
"The FBI does not typically release investigative details, like tips or leads," Ayn Sandalo Dietrich, a spokeswoman for the agency's Seattle office, said Tuesday in an email.
Makah tribal members told the Peninsula Daily News in August that Keyes was a model citizen in Neah Bay. He worked for the tribe, doing landscaping and putting out plants and flowers in the town.
When Keyes left Neah Bay, he moved to Alaska, a location from which he traveled extensively.
Anyone with information about Keyes or his possible victims should call 800-225-5324, or 800-CALL-FBI.
