Raleigh, N.C. — Two men were hospitalized after a tire-store worker and his son found them unconscious inside the business Saturday night.

Hunter Crowder said he and his father, Brent Crowder, had stopped by Atlantic Tire Service about 10 p.m. to pick up a car on which Brent planned to work over the weekend. They noticed that a cleaning crew was at the building, but something seemed odd, the younger Crowder said Sunday.

The Crowders looked around and found two members of a cleaning crew on the floor, Hunter said.

Brent Crowder, who works at Atlantic, and Hunter, 16, called 911, then pulled the men outside, Hunter said. Hunter, who said he has taken emergency medical training with the Eastern Wake EMS, began first aid.

The workers were cleaning the store at 2131 Harrod St. and were using propane, officials said.

Raleigh firefighters ordered their hazardous materials squad to the scene.

Police and firefighters both said Sunday morning that they were unable to provide the men's names. Their conditions at the hospital were unknown.
