HUNTSVILLE, Texas, Muharram 02, 1437, October 15, 2015, SPA -- A Texas man who killed a Dallas police officer outside a club has been executed, according to AP. Licho Escamilla was lethally injected Wednesday for the November 2001 death of Christopher Kevin James who was trying to break up a brawl involving Escamilla. James and three other uniformed officers were working off-duty security. Escamilla pulled out a gun and opened fire on them as they tried to end the fight. The bullets struck James twice and knocked him to the ground. Escamilla walked up to James and fired three more shots into the back of his head. Escamilla was already wanted in Dallas for a neighbor's shooting death weeks earlier. He became the 24th convicted killer put to death in the U.S. this year. Texas has accounted for 12 of the executions. --SPA 03:36 LOCAL TIME 00:36 GMT www.spa.gov.sa/w
