The FBI in Dallas is seeking information from people who may have had contact with confessed Alaska serial killer Israel Keyes during his Texas travels last year.
Keyes, who killed himself in an Anchorage jail cell in December, confessed to murdering at least eight people across the country, including 18-year-old Anchorage barista Samantha Koenig last February.
He was arrested in Texas in March after using a debit card stolen from Koenig's boyfriend.
The FBI says Keyes is believed to have visited the Post Oak Cemetery in the Glen Rose area between Feb. 12 and Feb. 16. During that same time period, Keyes' blue rental 2011 Kia Soul may have gotten stuck in a muddy, rural area, possibly near Cleburne.
Keyes admitted traveling through Cleburne, Azle and Aledo in February.
Anyone with information concerning Keyes is encouraged to contact the FBI at 1-800-CALL-FBI.
