KILLEEN, Texas -- A grand jury determined that police justifiably used deadly force against the gunman who killed 23 people and himself at a Luby's cafeteria in October.
The Bell County grand jury also found that three officers who exchange fire with George Hennard did not kill any of the Luby's patrons.
Killeen police said the grand jury's findings, released Wednesday, closed their investigaton of the nation's worst mass killing.
'We're happy to have it over with,' said Deputy Chief G.S. Griffin. 'The case is closed as far as we're concerned.'
Hennard, 35, drove his pickup truck through the front window of the crowded cafeteria at lunchtime and opened fire, killing or fatally wounding 23 people. Hennard then killed himself with a gunshot to the head during a gun battle with police.
Investigators were unable to determine Hennard's motive.
The 12-member grand jury ruled that Killeen police officers Ken Olsen and Al Morris and Department of Public Safety Trooper Jody Fore were justified in the use of deadly force against Hennard.
Olsen, the first law officer to arrive at the scene, said the grand jury findings also confired his belief that none of the 20 shots he fired at Hennard hit anyone else. Two of Olsen's bullets struck Hennard.
A DPS analysis showed that Hennard fired about 80 rounds from his two handguns during the 15-minute shooting spree, and about 30 shots were fired by police.
