LINCOLN, Neb. (AP) — A college gymnast injured in a 23-foot fall has left a Lincoln rehabilitation hospital after months of treatment for a brain injury.

Heather Boulais, of Laguna Niguel in Southern California, fell on Jan. 14 while installing aerial silks in a gym before a practice by the acrobatics team at Union College in Lincoln. She left Madonna Rehabilitation Hospital on Thursday.

Her father, Terry Boulais, said, “to see her stand, take the steps, is very humbling.”

The college says an investigation into the accident is continuing.
