Authorities are investigating whether a pair of pants with a cell phone and Chapstick in the pocket might be related to an armed robbery Tuesday night at a nearby restaurant.

Charleston County sheriff's deputies responded to the Sonic at 2868 U.S. Highway 17 north near Mount Pleasant about 10:20 p.m.

The assistant manager told deputies he had just finished counting the cash deposit for the night when two men with bandanas entered the restaurant and ordered him to lie down at gunpoint, according to an incident report.

One of the men grabbed the entire cash drawer and demanded the employee to give up his wallet, which he didn't have.

The men ran out of the store. A second employee hid from the suspects but said one of them was a black male, about 5-foot-8 and 170 pounds in his 20s. The other suspect's race was not clear because of the mask. He is described as about 5-foot-8 and 140 pounds. Both men wore a dark gray hooded sweatshirt, dark pants and a dark blue bandana.

A police dog tracked the suspects' scent to a treeline where they discovered pants with a cell phone and Chapstick inside the front pocket.

The robbery is still under investigation.
