Jordan Holgerson, 16, is recovering at PeaceHealth Southwest Washington Medical Center and is lucky to be alive, her mother, Genelle Holgerson, said by phone from the hospital Wednesday afternoon.

“She is lucky she is not paralyzed or dead. We’re lucky she is going to recover and not have permanent injuries,” said Holgerson, who is a medical assistant at St. John Medical Center in Longview.

A video of the incident shows that Jordan Holgerson was in a swimsuit, standing on the open side of the railing, her feet on the wooden arch that supports the bridge. Bystanders are heard counting down, “3 ... 2 ... 1.” Jordan hesitates; then the arms of another young woman flash into the picture and push Jordan off the span while she was looking toward the water. Jordan falls in a flat, laid-out position, screaming and flailing her arms, before she’s heard splashing into the East Fork of the Lewis River.

It was not clear whether she got out of the river herself or had to be rescued.

Genelle Holgerson said the identity of the person who pushed her daughter off the bridge is known and that she is an adult. The woman was apparently impatient or upset that Jordan did not jump off the bridge on her own, Holgerson said.

“I’m very upset with her. She is an adult, and I’m sure she should have known better. She could have killed my daughter.”

The Clark County Sheriff’s Office, which is investigating the incident, did not return calls for comment Wednesday afternoon.

In addition to breaking her ribs, Jordan suffered a bruised esophagus, injured her trachea and got air trapped in the lining of her lungs, Genelle Holgerson said.

“She is alert but in pain and is very tired,” said Holgerson, who had been by her daughter’s side since hearing about the accident at about 4 p.m. Tuesday. She was not sure now long her daughter will be in the hospital.

Jordan has a twin brother and two older siblings.
