Texas man who's sought DNA testing to prove his innocence slated for execution in 1998 stabbing death of woman, 85

A Texas man who's long sought DNA testing, claiming it would help prove he wasn't responsible for the fatal stabbing of an 85-year-old woman, was scheduled to be executed Tuesday evening.

Ruben Gutierrez was condemned for the 1998 killing of Escolastica Harrison at her home in Brownsville in Texas' southern tip. Prosecutors said the killing of the mobile home park manager and retired teacher was part of an attempt to steal more than $600,000 she had hidden in her home because of a mistrust of banks.

The inmate's lethal injection was planned for Tuesday evening at the state penitentiary in Huntsville.
