Minnesota Boy Dies in Playground Accident

A 12-year-old boy was found dead Sunday at a neighborhood park in Roseville, Minn., after receiving a blow from a rock flung by a makeshift slingshot connected to a jungle gym.

According to St. Paul Pioneer Press reports, Carter W. Geyen and a friend, also 12, were using a nylon sling and eight feet of surgical tubing connected to two posts to fling balls, rocks and other objects into the air, and the impact was powerful enough to create small craters throughout the playground.

Geyen died of apparent blunt-force trauma to the heart after he was struck by a five-pound rock that the man who discovered his body described to the Pioneer Press as being "bigger than his chest."
