LAKEWOOD, Wash. (May 26) - Troopers have arrested a man and a woman suspected of damaging at least 14 vehicles by throwing rocks onto them from a railroad trestle over Interstate 5 near Lakewood as a part of a bizarre stripping game.

Trooper Guy Gill says 23-year-old Joshua N. Sizemore and 18-year-old Amanda L. Madison were tossing baseball-sized rocks from the trestle early Monday. Sizemore, of Tacoma, and Madison, of Lakewood, were booked into the Pierce County Jail in Tacoma, Wash., for investigation of malicious mischief and second-degree assault.

Sizemore and Madison were tracked down by troopers on the ground with assistance from a State Patrol airplane that captured video of the couple throwing rocks. Investigators say Madison was in her underwear when police caught up with the couple.

Investigators say the couple was playing a stripping game, the rules of which involved Madison shedding a layer of clothes for every left headlight the two managed to bust. The same rule applied to Sizemore and right headlights.

Gill says the vehicles that were hit included a State Patrol cruiser. One person was injured when a rock crashed through the window and bruised his arm. He did not need to be hospitalized.
