AUSTIN, Texas (Reuters) - Texas on Wednesday is set to execute a man who shot and killed a security guard during a 1988 robbery at a Dallas grocery store.
Gayland Bradford, 42, would be the fourth person executed in Texas this year and second put to death using a new drug, pentobarbital, which is often used to euthanize animals.
On December 28, 1988, Bradford told his girlfriend he was going to make some money, showing her a gun before he left her apartment with two other people, according to a report by the Texas attorney general's office.
Later that night, he went to a grocery store and shot store security guard Brian Williams in the back. Bradford then took the guard's gun and shot him repeatedly while he was on the ground, according to the report.
Bradford told an accomplice to take Williams' money - $7. The accomplice also took personal items from Williams, including his hat and pipe. Williams died about an hour later, the report said.
According to the report, Bradford and the accomplice left without taking anything else. The store's security camera recorded the events and Bradford later confessed he went to the store to "get some money," and that he shot the guard, the report said.
Bradford's execution would be the 20th in the United States this year. There are three more executions scheduled this month in Texas, where more than four times as many people have been executed as any other state since the death penalty was reinstated in the United States in 1976, according to the Death Penalty Information Center.
