 A Texas man is facing execution tonight. Ruben Gutierrez was convicted of stabbing to death an 85-year-old woman in her home in Brownsville, Texas. Escolastica Harrison was a retired teacher and mobile home park manager who had hidden more than $600,000 in her home because she didn't trust banks. Gutierrez has said he didn't kill her. His attorneys say there's no physical or forensic evidence connecting him to the killing.
