Mich. student doing pull-ups dies in wall collapse

Police say an 8-foot wall collapsed in a Michigan high school locker room and killed a 14-year-old student who'd jumped and grabbed for the top to do a pull-up.

Williamston High School freshman Gabriel Corbett was buried under cement blocks Wednesday and later pronounced dead at a hospital. Police Chief Bob Young says it's not known why the interior wall came down.

School district finance chief Steve Cook says there hadn't been any reports of structural problems in the locker room, which was built in 1990.

A student told the Lansing State Journal he heard a noise and rushed into the locker room. He said he and others removed cement blocks that had fallen on Corbett.

Young says the teen was in "full cardiac arrest" before going to the hospital.
