GOSHEN, Ind.?A man opened fire Thursday at the simulated-wood factory where he worked, killing a co-worker and wounding several others before committing suicide, authorities said.

State Police officials said one person was slain inside Nu Wood Decorative Millwork factory. A SWAT team later found the gunman with an apparently self-inflicted gunshot wound.

“He was dead when they found him,” Sheriff’s Capt. Julie Dijkstra said.

Authorities said five people were treated for gunshot wounds, but their conditions weren’t immediately known. Earlier, the mayor and hospital administrators said they feared 30 to 35 people had been shot.

Workers told authorities an automatic weapon was used and some injuries appeared to be shotgun wounds.

The shooting jolted the community. Local schools told their students and faculty to stay indoors.
