Jeffrey Demond Williams, 37, Black, was executed in Texas.
Williams was convicted of fatally shooting Houston officer Troy Blando, 39, White, while Blando was handcuffing him on May 19, 1999. Williams shot Blando with a gun he had tucked under his shirt. Blando was watching a motel where car thefts were suspected when he saw Williams drive up in a Lexus that was reported stolen in a carjacking nine days earlier.
Evidence showed Williams gave investigators five taped confessions the day he was arrested. Williams said he fired in self-defense, feared Blando could have been a carjacker and didn't know Blando was an officer. In another confession, he acknowledged knowing he was shooting a policeman.
Court records show Blando, although in plain clothes, was carrying his badge around his neck. Williams became the 6th inmate to be put to death this year in Texas, the 498th overall since the state resumed capital punishment on December 7, 1982, the 12th inmate to be put to death this year in the USA and the 1332nd overall since the nation resumed executions on January 17, 1977.
