LUBBOCK, Texas (AP) -

The Texas high school made famous in the book "Friday Night Lights" says a longtime teacher who was among five former staffers accused of having improper relationships with students committed suicide a day after the allegations surfaced.

Mark Lampman taught government and coached girls' golf at Permian High School in Odessa for 17 years. School officials didn't detail his alleged relationship with a female student, but called it improper.

School district spokesman Mike Adkins said the school learned of the accusation Tuesday and that Lampman resigned after being questioned.

The Ector County sheriff said the 47-year-old died Wednesday of a self-inflicted gunshot wound. A woman who answered the phone at Lampman's home declined comment.
    
Two accused former staffers are awaiting trial, and police are investigating allegations against two others.
