According to the lawsuit, Gregory and the other victims “tried to exit the warehouse, but were unable to exit due to the unsafe conditions and configuration of the warehouse”

The warehouse in question was a converted space hosting a rave with musical guests. This was the deadliest building fire in the US in over a decade.

“It’s really horrific, irresponsible actions and inactions on the part of this building owner, those associated with this event, and the city that cost the life of this beautiful young lady and the lives of 35 others,” said Mary Alexander, the lawyer who filed the suit on behalf of Gregory’s parents.
