PITTSBURGH -- A former Duquesne University basketball player who was shot on campus has filed a federal lawsuit against the university.

Sam Ashaolu was seriously injured on Sept. 17, 2006, when he and four other players were shot while returning to their dorms.

The shooting happened after armed men attended a dance in the Duquesne Union, police said.

Those injured in the shooting were Ashaolu, Shawn James, Stuard Baldonado, Aaron Jackson and Kojo Mensah.

Ashaolu was struck in the head by two bullets. His lawsuit alleges negligence on several individuals and Duquesne University.

“I know that with other police departments, customarily when there are events emptying out, their police officers are to mingle with the crowd, walk through the crowd and show a presence so as to deter,” said Josh Geist, one of Ashaolu’s attorneys.

The lawsuit claims that university police did not do this the night of the shooting.

Ashaolu is back in class now, but he still struggles with flashbacks. Bill Goodrich, his other attorney, said, "He has been trying to pick up whatever pieces of his life are available to him."

The fourth and final suspect in the campus shootings at Duquesne University entered a plea in court on Tuesday.

James and Mensah are also suing the university. Their lawsuit claims that the school did not adequately protect the students, and they are seeking damages for the injuries they suffered.

Brittany Jones, a Duquesne student arrested in connection with the shooting, pleaded guilty to reckless endangerment. She received two years probation and a two-year ban from the campus.

Jones was the only Duquesne student arrested in the case. Police said she helped the male suspects, who were armed, sneak into the campus dance.

The three other suspects in the case all pleaded. Two admitted to the actual shooting, including William Holmes and Derek Lee. Lee was offered a lighter sentence than Holmes' because police said he fired fewer shots, and he did not hit anyone.

Another woman, Erica Sager, pleaded no contest to felony charges of inciting a riot. She received four years probation.
