CHICAGO (CBS) — The lawsuit filed by a 26-year-old woman who was paralyzed when a pedestrian shelter fell on her at O’Hare International Airport was headed to trial Tuesday morning.

Tierney Darden was seeking shelter from a storm at O’Hare in August 2015 when the 750-pound structure meant to protect her collapsed on top of her, severing her spinal cord.

The young dancer was paralyzed from the waist down, and has sued the city for negligence. After her accident, 2 Investigator Dave Savini exposed the shelters at O’Hare had been poorly maintained. The shelter that fell on Darden had rusted brackets and missing bolts.

The shelters have since been removed from O’Hare.
