Slim Jim manufacturing plant explodes.

From CNN:

Two people were found dead and a third person is still believed missing in a North Carolina food plant heavily damaged in a morning explosion, police said Tuesday night.

Four people were in critical condition after the explosion at the ConAgra Foods plant in the town of Garner, CNN affiliate WRAL-TV reported.

The explosion, reported about 11:30 a.m. Tuesday, caused sections of the roof to collapse. Search efforts for those missing were slowed by ammonia leaks and a fire that was not extinguished until afternoon.

[...] Police said recovery workers still were trying to get the two bodies out of the plant, which makes Slim Jim food products. The victims' names weren't immediately available.

More than 300 people were in the plant when the explosion happened, authorities said. The cause of the blast was unknown, according to Garner police spokesman Joe Binns.
