A Saturday night celebration turned into a Sunday morning tragedy at Texas A&M University, reports CBS News Correspondent Jim Axelrod. The six students were hit by a truck and killed, walking to a post-football game fraternity party.
The driver of the pickup truck, also a student, had fallen asleep, police said. Holland reports he will not be charged with a crime.
The accident happened just after midnight about two miles west of the Texas A&M University main campus, said police Maj. Mike Patterson.
The victims - four students from Baylor University, one from Texas A&M and one from Southwest Texas State - were among a group of people who were going to a party at the Tau Kappa Epsilon house along a four-lane highway. Some had just parked on the road shoulder and the pickup sideswiped two parked cars and struck a third.
Witnesses said parties at the fraternity often draw large crowds of people who must park on the shoulder of the highway, which has a 65-mph speed limit.
The man driving the pickup, also a Texas A&M student, had just taken his girlfriend home and was returning to campus when he fell asleep and veered off the road, Patterson said.
"We could hear screaming and stuff but at first we didn't have any idea he was running over people," said Daniel Lara, a 22-year-old student who lives next door to the fraternity. "We walked out and saw bodies all over the place."
"It was the most awful thing I have ever seen," said student Tara Martin, who had parked down the road and was also walking to the party. She said she tried to save Baylor student Erika Lanham, who had a faint pulse.
"I'll never forget looking at that girl's face," Martin, a Texas A&M sophomore who said she had lifesaving training, told KHOU-TV.
"Their shoes were in perfect place from where they were walking," said Arissa Hill, a freshman who was going to the party.
Hours after the crash, large puddles of blood were still visible at the scene.
The driver, 18-year-old Texas A&M student Brandon Kallmeyer, was not injured and apparently had not been drinking, police said.
Patterson said investigators will present evidence to Brazos County prosecutors without recommending charges.
The victims were identified as Emily Hollister, 18, Tricia Calp, 18, Dolan Wastel, 22, and Erika Lanham, age unknown, all Baylor students; William Flores, 22, of Southwest Texas, and Ted Bruton, 21, of Texas A&M.
Two other people were hospitalized, but their injuries did not appear to be life-threatening.
