Texas executed Richard Cobb on Thursday for the 2002 abduction and killing of a man outside of the town of Rusk, southeast of Dallas, the state Department of Criminal Justice said.

Cobb was convicted of kidnapping Kenneth Vandever, 37, during an armed robbery at an convenience store and then shooting him and leaving him for dead in a field.

Cobb was the fourth person to be executed in Texas this year.
