Police said three officers sustained minor injuries but no one was transported to the hospital. Savage told the Associated Press that no fatalities have been confirmed yet and the status of the suspect, who was in the home when it exploded, is not known.

The Bureau of Alcohol, Tobacco, Firearms and Explosives said federal agents and federal fire investigators were at the scene and assisting local authorities in the investigation. Police also said the investigation into the cause of the explosion was ongoing.
