One Ames teenager remains hospitalized after a June 22 single-car accident on Mortensen Parkway.

Justin Grall, 18, of Ames, was traveling east on Mortensen Parkway when Grall lost control of the vehicle he was driving. It went off the road at about 10:15 p.m, near the intersection of Mortensen and Big Bluestem Court.

A preliminary report provided by  Cmdr. Jim Robinson of the Ames Police Department said that the car struck a curb and turned over. Tyler Grieser and Zachary Toresdahl, both 18, of Ames, were also in the vehicle. Toresdahl was thrown from the car. 

Grall and Toresdahl were both transported from the scene by helicopter to Mercy Medical Center. Grieser suffered minor injuries and briefly left the scene before turning himself in to police and being taken to Mary Greeley Medical Center for treatment.

Though Toresdahl has been released from the hospital and is recovering at home with several broken bones, Grall remains at Iowa Methodist Medical Center in stable condition.

Grall suffered severe brain trauma and a fracture at the base of the skull. The extent of his brain injuries are still not fully known.

He began rehabilitation yesterday, a program that his parents say will run for four to six weeks. They said the amount of support shown by the community has helped both Grall and his family.

“The support we’ve gotten from people we don’t even know has been amazing,” said his mother, Babin Grall.

Babin has been updating a CaringBridge website to keep family and friends up to date on Justin’s condition. Justin’s friends have begun a medical fund to help the family defray the high costs of his treatment.
