HENDERSONVILLE — An explosion at a Hendersonville building has killed a father and injured his son.

A worker in the building used gasoline to loosen the carpet, said Henderson County Sheriff's Department Sgt. Randy Stepp.

``One of the witnesses heard the father say, `No, no, no.' Then the place blew up,'' Stepp said.

Dewayne Robinson, 35, died at the scene while his son, Dalton, was flown to N.C. Baptist Hospital in Winston-Salem for treatment. He was listed in critical condition today with burns over more than 50 percent of his body, said hospital supervisor Roberta Stutts.

The worker, Jorge Cevantes, and Robinson's 7-year-old daughter, Krystal, ran outside when the explosion occurred. Cervantes suffered a minor injury, but the girl did not appear to be injured, Stepp said.

Henderson County Fire Marshal Rocky Hyder said he found a plastic container inside the building that may have contained gasoline.

``It looks like an explosion or a fast-burning fire,'' he said.

Wendell Capes, the owner of the building, said Robinson lived nearby and kept a check on the structure for him. Robinson was Capes' son-in-law.

Stepp said investigators were looking into whether the boy may have ignited the fumes.

``By the father saying, `No, no, no,' we feel like the boy was doing something,'' he said. .
