Campus Prays for Answers After Shootings

Police said there had been bomb threats on campus over the past two weeks but that they had not determined whether they were linked to the shootings.

It was second time in less than a year that the campus was closed because of gunfire.

Last August, the opening day of classes was canceled when an escaped jail inmate allegedly killed a hospital guard off campus and fled to the Tech area. A sheriff's deputy was killed just off campus. The accused gunman, William Morva, faces capital murder charges.

Among the dead were professors Liviu Librescu and Kevin Granata, said Ishwar K. Puri, the head of the engineering science and mechanics department.

Librescu, an Israeli, was born in Romania and was known internationally for his research in aeronautical engineering, Puri wrote in an e-mail to The Associated Press.

Granata and his students researched muscle and reflex response and robotics. Puri called him one of the top five biomechanics researchers in the country working on movement dynamics in cerebral palsy.

Also killed was Ryan Clark, a student from Martinez, Ga., who had several majors and carried a 4.0 grade-point average, said Vernon Collins, coroner in Columbia County, Ga.

His friend Gregory Walton, a 25-year-old who graduated last year, said he feared the nightmare had just begun.

"I knew when the number was so large that I would know at least one person on that list," said Walton, a banquet manager. "I don't want to look at that list. I don't want to.

"It's just, it's going to be horrible, and it's going to get worse before it gets better."
