PITTSBURGH -- City police say they're still looking for the man who shot five Duquesne University students after a party at the private Catholic campus in uptown Pittsburgh.

Basketball players Sam Ashaolu, Stuard Baldonado, Kojo Mensah, Shawn James and Aaron Jackson were hit by gunfire early Sunday morning after "College Bash '06," a dance at the student union, police said.

Coach Ron Everhart told ESPN that the team went to the dance together and was standing outside a dormitory with other students when the shooting began at about 2:15 a.m.

Teammates knocked people to the ground and dove to safety, then joined with other students to drag the victims away and wrap tourniquets around their wounds until help arrived, Everhart said.

Ashaolu is in critical condition at Mercy Hospital with a head wound and Baldonado is in serious condition. Everhart said he has been sleeping in the hospital and has no plans to leave.

Mensah is at UPMC Presbyterian. Per a family request, no information is being released about him.

James and Jackson were treated and released for gunshot wounds to the foot and hand, respectively.

More than 300 students prayed for the victims during a standing-room only Mass on Sunday night at the university chapel.

"We are a tight-knit community. What affects one of us affects all of us," the Rev. Timothy Hickey said. "We are family and we care for one another. We care for you."

In a letter to parents posted on www.duq.edu, university President Dr. Charles Dougherty described the suspect as "an unaffiliated gunman" who came on campus to attend the dance and got into an argument with the players.

"There is no doubt that our students are the victims," the letter said. "They had no weapons. There is no evidence of alcohol or drug use among our athletes. They did nothing to provoke this sort of violent response."

Pittsburgh police have not said what sparked the dispute. According to witness accounts, it may have involved a girl at the party.

The shooter is described only as a black man, about 5 feet 4 inches tall, who was wearing a white T-shirt.
