Three people were killed in a fire in Benton Harbor.

The Benton Harbor Department of Public Safety was called just before 5 a.m. on Sunday, Nov. 1, to a structure fire at 185 Bellview in the city of Benton Harbor.

The structure was a duplex, with a family of four living in the upstairs apartment.

Upon arrival, firefighters attempted to make entry to search for any occupants and to begin an interior attack. However, the heat and flames were such that it prevented entry into the structure.

Moments later, the second floor collapsed down to the first floor.

Three of the occupants perished in the fire. The victims include a 30-year-old mother, a 15- year-old son, and a 12-year-old daughter.

The father is the sole survivor and is being treated for smoke inhalation and a minor injury.

The cause of the fire is currently being investigated by Benton Harbor Department of Public Safety and the Michigan State Police Fire Marshal.
