A young North Carolina woman’s body was recovered days after she jumped off a boat and drowned in a South Carolina lake — and authorities say that many “unanswered questions” remain about the mysterious incident, according to a new report.

Krista Lee Philemon, 22, of Monroe, jumped off a boat with several others Sunday night into Lake Watertree, a 19-square-mile reservoir that spans three counties, local station WLTX 19 reported.

Philemon never emerged — so someone called 911, according to the report.

After an extensive search involving multiple agencies, her body was recovered just before 7 a.m. Tuesday by the South Carolina Department of Natural Resources, the department said in a tweet.

The Kershaw County coroner has since confirmed her identity.

“Trying to recover, especially in Lake Wateree, is difficult,” Camden Fire Chief John Bowers told the station. “You don’t have any visibility, so getting a good spot is very important but is also very difficult.”

“There are a lot of unanswered questions,” he added. “We don’t know why this happened.”

Philemon’s cause of death has been confirmed as drowning — but the details still need to be figured out, he said.

“We know the combination or sequence of events that led up to this tragedy, but we don’t know the details [on] what caused the young lady to lose her life that night,” the fire chief added.

Bowers told the station that Philemon’s family offered some information that “helped speed the investigation and recovery along.”

“It’s always difficult to see the families and their suffering through an event like this,” he said.

Natural Resources officials told local station WSOC 9 that Philemon was not wearing a life jacket when her body was found, and that they do not suspect foul play.

Philemon graduated at the top of her class at Piedmont High School, the outlet reported.

“She was really nice and always doing stuff around the school,” former classmate Kole Vonegidy told the station.

She enjoyed painting and recently launched the nonprofit Painting with a Purpose, which raised hundreds of dollars in support of local charities, relatives said.
