Execution of Clayton Lockett

The death of Clayton Darrell Lockett occurred on April 29, 2014, when he suffered a heart attack during an execution by lethal injection in the U.S. state of Oklahoma. Lockett, aged 38, was convicted in 2000 of murder, rape, and kidnapping.

Clayton Lockett was born in 1975 to a drugusing mother. She abandoned him when he was three years old, and he was then raised by his father who severely physically abused him throughout his childhood, gave him drugs starting at age 3, and encouraged him to steal and not get caught.
