The fire happened at Westover and South Wayside around 2:30am. Robertson's found dead in the trailer.
Four people were inside the home adjacent to that trailer when the fire broke out. Tonya Cooper was one of the women inside the house. She says someone pounded on her door screaming that the trailer was on fire.
Cooper tells us her heart sank because she knew Robertson, a family friend who needed a place to stay, was inside the trailer.
Tonya Cooper said, "We were trying to get in there because we knew someone was in there. We couldn't get him out."
Family and friends say Robertson was last seen watching TV around 10:30pm.
Barbara Robertson, his wife, said, "He was just an ordinary guy...he was down with everything."
HFD says there is a possibility that a space heater may have started the fire because an electrical cord was connected to a heater inside the RV. No foul play is suspected at this time.
Four people have died in the last three days in fires.
