Lawyers for the coaches and players on the Bluffton University baseball team who were involved in a deadly bus crash in March have asked a federal court to determine whether they are entitled to insurance money, the Associated Press reported.

A lawsuit filed last month in the U.S. District Court in Toledo, Ohio, says the bus driver and the bus company were insured under three policies issued to the university totaling $21-million. The insurance companies have argued that the driver and company were not covered, the lawsuit says.

The lawsuit is necessary so the victims can clarify the amount of coverage before they file any individual claims, said a lawyer for the family of David Betts, one of the players who died.

Four students from the Division III institution in Bluffton, Ohio, were killed in the accident and a fifth died later of injuries suffered when a team bus plunged off an interstate overpass in Atlanta on the way to a spring-break tournament in Florida. The bus driver and his wife also were killed.

The National Transportation Safety Board is still investigating the accident. —Brad Wolverton
