A Texas inmate set to be executed for the slaying of a 93-year-old woman during a robbery a decade ago is seeking a delay.

An appeal filed late Wednesday in state court contends that the scheduled execution of Clifton Lamar Williams on Thursday evening should be delayed. It cites an error in an FBI database used by two witnesses testifying at Williams' trial in 2006.

Williams was convicted of for killing Cecelia Schneider at her home in Tyler.

Prosecutors argue that revised statistics from the database used to calculate population odds and DNA probabilities don't affect the overwhelming evidence of Williams' guilt.

The 31-year-old Williams would be the 10th inmate to receive a lethal injection this year in Texas, which carries out the death penalty more than any other state.
