A teenager who kept a 29-inch sword displayed on his bedroom wall has died after the weapon fell and slashed his shoulder and neck, authorities said.

Joshua Hershberger, 15, was in his bedroom with two younger siblings Monday night when a ball they were bouncing knocked the sword off the wall, the Hillsborough County Sheriff's Office said.

The high school sophomore was pronounced dead at a hospital in Brandon, a suburb of Tampa. Police said no charges were expected.
