Teen tubing down river has 250 man jump from bridge

What was supposed to be a relaxing afternoon on the river for an Idaho couple turned into a nightmare when a 250-pound man jumped from an overhead bridge and landed on her abdomen.

“I just want them to come forward and own up to their mistakes,” her boyfriend Justin White-Ammons, told InsideEdition.com.

He and his girlfriend Cienna Cook, 19, were spending a Sunday tubing down the Boise River earlier this month. He recalled lagging a couple yards behind due to the flow of the current.

White-Ammons, a student at Boise State University, said he saw a couple of men on the Baybrook Bridge above the river, joking about whether or not they should jump in.

Next thing he knew, one of the men, who appeared to weigh about 250 pounds, jumped in feet first, landing on Cook in her tube. Cook was underwater, struggling to get to the surface.

“I had to do a double-take to make sure it was Cienna,” White-Ammons said.

He then jumped out of his own tube to make sure Cook was OK. But by the time he got to her, several girls had already pulled her out of the water and helped her to the shore.

"She was having extreme pain in her side and there were some markings on her lower abdomen and on her leg,” he explained. “It was hard for her to stay awake. She was really close to passing out and [when I] looked at her, her face was turning blue, her lips were blue, she was really turning blue." 

At that point, the 250-pound man who jumped, as well as his cohorts, was nowhere to be found.

Cook was rushed to the hospital, where they determined she had suffered internal bleeding as a result of the incident.
