HUNTSVILLE, Texas (AP) — Texas executed a condemned inmate on Thursday for orchestrating and taking part in the robbery and killing of a man in Amarillo 13 years ago.

"Blessed are they that mourn, for they shall be comforted," Larry Donnell Davis said in his final statement, quoting from the Bible. "It is finished."

The parents of Davis' victim watched through a window a few feet from him but he never looked at them. He was pronounced dead at 6:19 p.m. CDT, eight minutes after the lethal drugs began to flow.

Davis, 40, had been out of prison less than four months when authorities said he and several friends were involved in robbing an acquaintance, Michael Barrow, 26, and killing him at Barrow's home.

Davis' execution was the fourth in Texas this year and the second in as many weeks. Davis was among at least 15 condemned prisoners with death dates in the coming months, including six in August.
