MOBILE, Ala. (AP) -- A judge has dismissed a family's lawsuit against the University of South Alabama over a campus police officer's fatal shooting of a naked student.

A Mobile County judge ruled Friday that state law makes the school exempt from the wrongful death lawsuit filed by the parents of 18-year-old freshman Gil Collar.

The judge says the lawsuit can go forward against the university's police chief, however.

A university police officer shot and killed the Wetumpka teenager outside the police station in October.

Authorities say Collar was nude and appeared to be on drugs, and he threatened the officer.

The lawsuit says the shooting was unjustified. An attorney for the family didn't immediately return a message seeking comment.

The family also is suing the officer who fired the fatal shot.
