A woman and 12-year-old girl were killed in a Neshannock Township house fire Thursday morning. 

Police, firefighters, and the Lawrence County Coroner were called to a fully involved house fire that shut down a road in the township just before 9 a.m. at a home on the 2900 block of Old Plank Road.

The Lawrence County Coroner says 12-year-old Jazmyn Keller and 48-year-old Melanie Keller were pronounced dead at the scene. 

Firefighters say the flames had spread throughout the home and the garage.

The coroner's office, the Neshannock Township police and fire department, and the fire marshal are all investigating.
