WILSON, N.C. (AP) – A North Carolina sheriff says there were suspicions that the heist of millions in gold from an armored truck was an inside job.

Wilson County Sheriff Calvin Woodard acknowledged during a news conference Wednesday that those suspicions were noted in a search warrant.

Asked to elaborate, Woodard said that the warrant was written in a hurry before the victims, who spoke little English, could be thoroughly interviewed in Spanish.

Woodard says the men were currently considered victims and not suspects, but all possibilities are being investigated.

Woodard said the men stopped for gas in Dillon, South Carolina, near the North Carolina line. When they were driving through North Carolina, the passenger in the truck started to feel sick and said he smelled gas.

However, after deputies arrived a mechanic found no problems with the truck.
