MYRTLE BEACH, S.C. — Two days after an explosion and fire claimed the lives of a mother and her son at a Myrtle Beach campground, investigators were still working to figure out how it started.
The Horry County coroner identified the two people who died as Shelby McGuire, 62, and her son Cory McGuire, 37. Another person was injured.
Channel 9 checked with authorities Thursday, who said that the investigation would take some time and that they were being diligent in their investigation.
In a photo sent to Channel 9 by a viewer who is visiting Myrtle Beach, a giant fireball is seen coming from a trailer early Tuesday morning at the Apache Family Campground and Pier.
Channel 9 also received a video from a viewer showing the fire after the explosion.
Melissa Dewett from Huntersville has been staying at the campground since Easter. She spoke to Channel 9 over the phone and said she heard the explosion.
"All of a sudden this loud explosion happened," Dewett said. "This massive flame. I was like, 'Oh my God.'"

Dewett said the family lived at the campground year round.
"I see the mother and son walking all the time. Up on the pier all the time. They go for their daily walk. They were the sweetest people," Dewett said.
Firefighters from Horry County, Myrtle Beach and North Myrtle Beach had the fire under control within an hour.
The cause of the fire is under investigation.
