CONROE, Texas -

Divers recovered the body of the third victim killed in a boating accident on Lake Conroe Tuesday night.

The body of Kristina Cole Frost, 29, was found in 30 feet of water around 2 p.m. Wednesday. She was thrown from a pleasure craft that collided with another boat around 9 p.m. Tuesday.

Frost's 9-year-old son Jason died of injuries from the accident at a Houston hospital Tuesday morning. Her sister, Leilani Cole, 30 was pronounced dead at the scene.

Cole's mother and other family members maintained a day-long vigil at a boat ramp near the Seven Cove's subdivision on Lake Conroe until Frost's body was recovered.

"I had two lovely daughters and one grandson and they lost their lives, and I deeply regret that," Ellen Cole said.

There were eight people aboard the 21-foot pleasure boat when a boat carrying two fishermen, heading back from a bass fishing tournament, slammed into them.

Brandon Wilson, 45, was piloting the pleasure craft. After visiting him at Ben Taub Hospital Tuesday, Wilson's brother, Chris, told Local 2 News that Wilson told him the other boat was speeding and may not have had its running lights on.

"It was a horrible accident,” Chris Wilson said. "I talked to my brother in the hospital. He says the bass boat was going really fast when it slammed into his boat. He grabbed the little girl on board and they were both thrown into the water. He could hear her screaming and he tried to swim to her, but that’s when he realized both of his legs were crushed by the boating accident."

Wilson's brother remains hospitalized, along with a 3-year-old girl and a 10-year-old girl who were also a passengers on this boat. Two teen boys riding with him were not hurt.

The two men in the other boat told investigators the pleasure craft did not have its lights on.

Montgomery County Prosecutor Warren Diepraam said so far there is no indication of any wrongdoing.

"We're treating it as a criminal investigation at this point because that is the prudent thing to do until we can prove otherwise,” Diepraam said.

Both occupants of the fishing boat were hospitalized. One of them is identified as country singer Josh Ward.

Ward was released from the hospital Tuesday. He left a message on his Facebook page telling fans, "At this moment I ask everyone to keep the victims and the families of the people involved in this tragic accident in your thoughts and prayers."

Investigators said as of right now there is no indication that drugs or alcohol are involved. However, the investigation continues.

The wreckage is being reassembled at the Coast Guard station on Lake Conroe to reconstruct the accident. Investigators said they'll be trying to determine how fast both craft were traveling, if their lights and safety equipment were working and if the people in both boats were wearing life jackets.

No charges had been filed as of Wednesday night.
