Texas executes man for corrections officer's death

A Texas inmate has been executed for the death of a corrections officer during a short-lived escape from prison six years ago.
Jerry Martin had requested that no additional appeals be filed on his behalf, clearing the way for his lethal injection Tuesday evening.
Martin was serving 50 years for attempted capital murder when he and another inmate bolted from a work detail outside a Huntsville-area prison in September 2007.
In the ensuing chaos and gunfire, a 59-year-old prison officer on horseback, Susan Canfield, suffered fatal head injuries. Both Martin and his partner, John Falk, were captured within hours after fleeing in a stolen pickup truck.

Martin's execution was the 16th and last scheduled for this year in Texas, which carries out capital punishment more than any other US state.
