WACO (January 17, 2013)--The FBI is asking for the public's help as agents try to retrace the steps of a serial killer they believe frequented locations in Central Texas while on killing sprees.
Israel Keyes committed suicide while in federal custody in Alaska in December 2012, but FBI agents believe between 2001 and March 2012, Keyes committed several kidnappings and murders, according to FBI Special Agent Diego Rodriguez, special agent in charge of the Dallas FBI field office.
Keyes, who killed himself in December in his jail cell in Anchorage, confessed to murdering at least eight people across the country, including Anchorage barista Samantha Koenig, 18, who was killed last February.
He was arrested in March in Texas after using a debit card stolen from Koenig's boyfriend.
Based upon investigation after his arrest, Keyes is suspected of traveling through various cities in the Dallas-Fort Worth and Glenrose areas in February 2012.
In a news release issued Thursday, Rodriguez said the FBI is "attempting to identify the extent of Keyes' travels and activities and is seeking the public's assistance specifically as it pertains to the (those areas) during the time period of February 12 through February 16, 2012.
Rodriguez said prior to his suicide, while in custody, Keyes admitted traveling through the cities of Azle, Aledo and Cleburne in February 2012.
During the time agents believe Keyes was in Central Texas, he was driving a rented Blue 2011 Kia Soul with Texas license plate number CN8 M857.
The FBI thinks Keyes may have visited the Post Oak Cemetery in the Glen Rose area between Feb. 12 and Feb. 16 and that during that same time period, his rental Kia may have gotten stuck in a muddy, rural area, possibly near Cleburne.
The FBI is asking anyone with information about Keyes or the vehicle to call 1-800-CALL- FBI or any local law enforcement agency.
