Texas man who killed woman in 2000 addresses victim's family moments before execution: "I sincerely apologize for all of it"

A Texas man who unsuccessfully challenged the safety of the state's lethal injection drugs and raised questions about evidence used to persuade a jury to sentence him to death for killing an elderly woman decades ago was executed late Tuesday.

Jedidiah Murphy, 48, was pronounced dead after an injection at the state penitentiary in Huntsville for the October 2000 fatal shooting of 80-year-old Bertie Lee Cunningham of the Dallas suburb of Garland. Cunningham was killed during a carjacking.

"To the family of the victim, I sincerely apologize for all of it," Murphy said while strapped to a gurney in the Texas death chamber and after a Christian pastor, his right hand on Murphy's chest, prayed for the victim's family, Murphy's family and friends and the inmate.
