The people were wearing respirators that allowed them to breathe the toxic fumes. Bottles of sulfuric acid and what appears to suicide letters were found nearby.One guest said the maintenance worker who discovered the scene told him the guest left a "sign on the mirror that they died from carbon monoxide and that their bodies were in the restroom."Tiffany Crowder arrived at the motel to see if her sister was one of the women."Sergeants can't tell us the names of the two bodies or people who went to the hospital," Crowder said. "I just want to know if it's my sister."After the crime scene tape was removed, many guests started making their way to their rooms.
