Authorities say a volunteer firefighter was shot to death when responding to a medical emergency call at a rural home near Little Rock.

Pulaski County Sheriff's Office Capt. Carl Minden says the firefighter with the East Pulaski Volunteer Fire Department was responding to the call at about 5 a.m. Friday when he was shot by a man at the home. Minden says the firefighter, whose name has not been released, later died at a North Little Rock hospital.

Minden says a suspect in the shooting is being questioned by police. A motive is not yet known.

The fatal shooting happened as heavy snow was falling in the area, and Minden says the weather has slowed the investigation so far.
