COLLEGE STATION, Texas (AP) _ A grand jury has decided not to indict an 18-year-old Texas A&M student who fell asleep while driving and ran down a group of students en route to a fraternity party, killing six.

Brandon Michael Kallmeyer of Katy was driving home Oct. 10 when he fell asleep and veered off the road. His pickup truck plowed into people getting out of their cars or walking to the party near the campus hours after A&M's football team played Baylor.

District Attorney Bill Turner said the grand jury found insufficient evidence to indict Kallmeyer on a charge of criminally negligent homicide. Kallmeyer was returning to College Station after dropping off his girlfriend and her parents in Independence. Killed in the accident were four students from Baylor University, one from Southwest Texas State, and one from Texas A&M. Two other people were injured.

Kallmeyer's mother, Rhonda Kallmeyer, said her family was relieved but knew the grand jury's decision would ``do nothing to relieve the loss and sadness of everyone involved.''

The accident was among three tragedies related to Texas A&M last fall.

On Sept. 18, five people were killed in the crash of a plane used by an A&M-connected skydiving club. On Nov. 18, 12 students were killed and 28 others were injured when a 40-foot pyramid of logs erected for the school's football bonfire collapsed.
