“…construction at a store inside the mall caused the leak…Amy Towne, the manager at the luggage store Tumi, said she was rushed to the emergency room after falling ill at work.

‘Around noon-ish I wasn’t feeling well. I was feeling really tired, dizzy, lightheaded, and nauseous,’ Towne explained. ‘It wasn’t until the fire department showed up in the store, which was after 1:30 p.m. that we were told there were high levels of carbon monoxide in our building and we had to evacuate.'”
