Rock kills passenger

KNOXVILLE, Tenn. – Four men were arrested Tuesday in the death of a passenger who was struck by a 10-pound rock dropped from a highway overpass, authorities said.

Two of the men apparently told family and friends that they were involved in the death of 69-year-old Barbara Weimer, according to Sheriff Tim Hutchison.

Hutchison said investigators found a van they believe the suspects were driving when the bowling ball-size rock crashed through the sport utility vehicle’s windshield on Interstate 75. Bricks and rocks similar to the one that hit Weimer were inside the van, he said.
