The FBI has asked for the public's help in tracking where a confessed serial killer traveled in Texas before his capture and eventual suicide.
Investigators on Tuesday released a Texas timeline on Israel Keyes in an attempt to identify more possible victims.
Keyes allegedly killed 11 people before his March 2012 arrest in Lufkin for speeding. He committed suicide last December in Alaska while awaiting trial in the rape and strangling of a coffee stand worker. The victim was Samantha Koenig.
The FBI says Keyes in February 2012 rented a blue 2011 Kia Soul in Houston, visited family in the Dallas area and possibly traveled through Azle, Aledo and Cleburne.
Keyes apparently visited Post Oak Cemetery in Glen Rose in February 2012, before using an ATM at the Peoples State Bank in Shepherd and withdrawing cash from an ATM at the Humble Community Bank. Both ATM transactions happened in March 2012.
Based upon investigation, the FBI says Keyes is believed to have committed at least eleven kidnappings and murders across the country between 2001 and March 2012.
Anyone with information about Keyes is asked to call 1-800-CALL-FBI.
Below is one of the interviews conducted with Keyes during his incarceration in Alaska.
