The most recent robbery occurred Thursday morning, at about 4 a.m. A man entered the Sunoco, 4001 Memorial Boulevard, dressed in all black. A black hoodie covered all but his eyes.
According to Kingsport Police Department Det. Frank Light, the suspect demanded money from the register and the clerk complied. He then demanded the clerk's wallet, which was also handed over.
The man also stole several six packs of beer, which he toted away in a bag he brought into the store.
Det. Light said a K-9 unit was called to the scene, and followed a trail for a short distance. However, it went dead at a nearby roadway, and police believe he left the scene in a car.
The store was robbed in almost identical fashion on Nov. 9, by what police suspect is the same man.
In that incident he entered at about 1:30 a.m. holding a machete, and fled with money and cigarettes.
Police are asking anyone with any information about the crime to contact the Kingsport Criminal Investigation Division at (423) 229-9429.
