FROSTBURG, Md. (AP) -- State fire marshals suspect a wood stove may have caused a fire that killed two Frostburg State University students in an off-campus apartment building in downtown Frostburg.

Deputy State Fire Marshal Bruce Bouch said Friday that the stove was in a first-floor common area in the rear of the building where the fire originated around 4 a.m.

The victims, 23-year-old Evan Kullberg of Frostburg and 20-year-old Alyssa Salazar of Annapolis lived together on the second floor.

Bouch says 10 occupants escaped the five-unit building.

He says two firefighters and a Frostburg police officer were treated for injuries including smoke inhalation and a burn.

Kullberg was a co-owner of Malino's Pizza Shop on the building's first floor.
