UPDATE: Lincoln school intruder sex assault case

A Nebraska Supreme Court ruling will allow the family of a boy who was sexually assaulted by an intruder at his school to argue that school officials should have done more to protect him.

A ruling released Friday revived the family's lawsuit against the Lincoln school district. The court said that Lancaster County District Court should examine the facts of the assault to determine whether the district did enough to protect the boy.

Previously, a district judge had ruled the school district wasn't responsible, because the assault couldn't be foreseen. The case involves a 2005 incident in which a kindergartner was sexually assaulted by a stranger in Arnold Elementary.

 Thirty-two-year-old Joseph Siems is serving 20 to 30 years in prison for the assault.
