Fort Hood attack stirs painful memories for '91 massacre survivor

Killeen, Texas (CNN) -- It was an autumn afternoon in Killeen, Texas, when a lone gunman wielding two handguns methodically shot victim after victim. By the time the rampage was over, a terrified community was left looking for answers.

But this wasn't last week at Fort Hood; this was 1991, when a man named George Hennard crashed his pickup truck into a Luby's Cafeteria and went on a shooting spree that left 23 dead and another 20 wounded before Hennard shot himself.

One of those wounded was Kirby Lack, minister of a small local church. Thursday's shooting at nearby Fort Hood brought back memories of that day more than 18 years ago.

"He started shooting people, and I dove under a table and that's where we stayed," Lack recalled in an interview with CNN. "The biggest feeling was just helplessness."

Lack's lunch partner, veterinarian Michael Griffith, was the first to die. Lack, after being shot once in the back, played dead, lying face down on the floor and trying not to move. But the killer approached him again.

"He literally pushed the barrel of the gun to the back of my head and applied pressure. I said my last prayer. I thought my life was over and I was going to die and go home and be with God," Lack said.Read more.

Army investigators on Sunday asked troops and civilians for help in the probe of a deadly mass shooting at Fort Hood last week, saying some who fled the gunfire might have evidence.

"The Fort Hood office of the U.S. Army Criminal Investigation Command is seeking any military or civilian personnel who may have left the scene ... with gunshot damage such as damaged privately owned vehicles, personnel clothing, etc.," investigators said in a written statement. "CID is also seeking any military or civilian personnel who may have inadvertently left the scene of this incident with material that could be used as firearms residue related evidence such as shell casings inside the boot, etc."

The statement said such objects would help Army investigators and the FBI "in their bullet trajectory analysis of the scene, to insure the comprehensiveness of the ongoing investigation."

Thirteen people -- a dozen soldiers and a civilian -- died Thursday in the shooting at the Fort Hood Army Post. Some 42 people were wounded, according to the post's public information office. It was unclear how many of those suffered gunshot wounds. Read More
