Jesse Wade Hancock, 48, was found dead inside his home at 116 East Main Street in Goreville, Illinois, after it caught fire Tuesday morning.
His family tells Local 6 that crews found him near the back door, where it's believed he was trying to escape.
They were told Hancock's body was badly burned.
The family says investigators think lightning may have struck a large antenna on the roof of the home, starting the fire.
The Illinois State Fire Marshal is trying to confirm that.
