(Pelion, SC) -- A grieving mother has questions after a teenager's death in Orangeburg County.
Eighteen-year-old Marcus Dwyer drowned this weekend in the Edisto River in Carson Park, just weeks before he was set to graduate from Pelion High School.
His mom tells News 19 Dwyer couldn't swim, and she doesn't understand why he would have been in the water.
Deputies say they're investigating, but, at this point, there are no signs of foul play.
