Karl was able to get away with his crime for 5 yrs before being caught. He was interviewed and the partial prints found on a roll of duct tape came up with no results but the Dallas police department decided to reopen the case and that's when Karl's fingerprints came up as a possible match. He claimed to be remorseful. I find it uncomfortable that he smiled at Felicia's family when they didn't even forgive him. Also, he spent years in AA but no one in his life ever saw him intoxicated. He was sentenced to death and executed.
