Large quantities of cell phones recently sold at Walmart stores at Jackson, Cape Girardeau, Columbia, Macon, and Lebanon, Mo. have set off some alarms.

Jackson Police Captain Rodney Barnes confirms 48 pre-paid cell phones were purchased at the Walmart in Jackson on Friday, Dec. 4.

Cape Girardeau Police Chief Wes Blair says up to 10 pre-paid cell phones were purchased the same day at the Cape Girardeau Walmart.

Both the Jackson and Cape Girardeau police departments turned over their investigations to the FBI.

A witness who does not want to be identified says that she and a family member saw a man with several pre-paid cell phones in his shopping cart Friday at the Cape Girardeau Walmart on William Street. She thought it was suspicious and wondered if maybe he was going to re-sell them
