Three more victims have been identified in the Bahamas helicopter...

The West Virginia billionaire killed in a helicopter crash off the Bahamas died alongside one of his daughters and some of her pals, according to family and reports.

Chris Cline — a coal tycoon who once dated Tiger Woods’ ex-wife, Elin Nordegren — was killed Thursday, a day before his 61st birthday, when the chopper crashed around 2 a.m. shortly after taking off from Grand Cay in the Bahamas, the Register-Herald reported.

The mining entrepreneur’s 22-year-old daughter Kameron was among the seven victims on the submerged aircraft, which was discovered overturned two miles off his private island.

“We are all so deeply saddened to announce the deaths of our beloved father Chris and our sister Kameron. This loss will be felt by all those who had the privilege of having known them,” Cline’s family said in a statement to WSAZ News.

“Chris was one of West Virginia’s strongest sons, an American original, full of grit, integrity, intelligence and humor, a testament that our hopes and dreams are achievable when we believe and commit ourselves to action,” the statement continued.

“Our sister, Kameron was a bright light to all who knew her, loving, smart, compassionate and full of joy and enthusiasm for life and other people. Their legacy of love and inspiration will live on through all of us. We love and miss them dearly but take comfort knowing they are with God now. We ask for prayers and privacy in our time of grieving.”

Kameron, who recently graduated from Louisiana State University, was joined on the flight by her Phi Mu sorority sisters Jillian Clark and Brittney Searson, The Advocate reported.

The trio was killed in the crash along with another pal, 22-year-old Delaney Wykle, who graduated this spring from West Virginia University with a nursing degree, friends said.

“She was a very caring young lady. She just loved everybody,” family friend Tammy Cline told The Post. “She just felt like it was a career that she could help people”

Wykle, who recently passed her nursing board exam, had been friends with Kameron since grade school.

“This was supposed to be a celebration for Fourth of July with [Kameron] and the other two girls from LSU,” said Tammy Cline, who is a distant relative of the entrepreneur.

The helicopter was headed to Fort Lauderdale due to the possible illness of someone on board — but the pilot “made no request or permission to go” before the flight, according to the Register-Herald.

Bahamian officials said the cause of the crash is under investigation.

“They’re attempting … to first of all go to the helicopter and retrieve any souls that are onboard and start the investigation,” Minister of Tourism and Aviation Dionisio D’Aguilar told the Nassau Guardian.

Cline was the founder of coal mining firm Foresight Energy, and was estimated to be worth $1.8 billion at the time of his death, according to Forbes.

He lost his first wife to cancer and his second marriage ended in divorce, according to the Register-Herald. In addition to Kameron, he was the father of three other children, Candice, Alex and Christopher.

Cline started dating Nordegren in 2013 following her highly publicized divorce. Page Six last spotted the on-again, off-again couple together in 2016.
