A northern Indiana sheriff says three people are dead following a shooting outside a furniture plant.

White County Sheriff Patrick Shafer tells WLFI-TV that two men died at the scene Tuesday. A woman was pronounced dead at a hospital.

Shafer says detectives found a box and a handgun at the shooting scene at Jordan Manufacturing in the city of Monticello, about 70 miles northwest of Indianapolis.

Authorities were withholding the victims' names. Other details were not immediately available.
