Homeowners heard the cries for help and rushed to the scene.
"I thought we were going to save the girl," neighbor Eric Justason said. "I thought we were going to do it."
Justason lives on Mayo Lake in Roxboro. He says his family had just finished dinner and they were enjoying the stars on the patio when they heard a sound coming from the water.
'We were listening and we heard the horrible words, 'where is my wife,'" Justason said.
Justason and his friend heard the cries for help and got in their boat.
They headed to the scene of the accident at the cove and saw a red pontoon boat.
"The guy did not know where his wife was, so Mark and I started a pattern and some circles," Justason said. "We found a young lady in the water little bit underwater."
It happened around 10 p.m. Sunday night. Justason says it looked like a boat flew over top of the pontoon boat, taking the woman with it. They found her underwater and tried to save her, but weren't successful.
"We had some neighbors down here who assisted with CPR on her and EMS showed up ? by the time we hit shore and that point they took control of the scene," Justason said.
He says the boat's driver took off, but they tried to stop him.
"A boat passed us non-illuminated, going like a bat out of hell, we lit him up so we could get a good view on him," Justason said.
He says the three other people in the boat were okay. One was cut badly, but alive.
Justason gave a statement to North Carolina Wildlife Resource Officers on Monday morning. ABC11 Eyewitness News contacted wildlife officers several times, but they had very little to say about their investigation.
