A third fire happened early Sunday morning in Chillum.

The Prince George’s County Fire Department said the fire happened at a home in the 5900 block of Riggs Road.

Firefighters were able to rescue a 55-year-old man who was trapped inside. The man, Norman Rogers, of Hyattsville, was taken to an area hospital where he later died.

Two other adults inside the home were able to escape.

Officials said one of the four fires was caused by unattended cooking and urged people to practice fire safety measures ahead of time.
