RAGLEY, La. (KPLC) - The State Fire Marshal’s Office says its investigators have determined that the deadly house explosion in Ragley over the weekend was likely due to a propane leak.

During their investigation, deputies say they learned the house, which was newly constructed, used propane as a fuel utility. On the day of the explosion, the family, with help from the relatives, were in the process of moving in when the explosion happened.

The Louisiana Fire Marshal’s office determined at the time of the explosion, there were a total of six people in the home instead of the seven initially reported. Five are still hospitalized in facilities across the state.
