Lexington police were using footprints in the snow to track a man who robbed a Subway on Wednesday night.
However, the tracks ended nearby and, despite help from police dogs, officers had not found the perpetrator about an hour and a half after the crime.
The man, wearing a ski mask and carrying a black handgun, walked into the Subway at 2358 Nicholasville Road near Malabu Drive just before 9 p.m.
After he demanded money, the clerk gave him an undisclosed amount of cash, police Lt. Dean Marcum said. The man then left through the back of the restaurant.
The footprints gave police a few clues, namely that the robber ran toward Malabu Drive and that he was wearing sneakers, Marcum said.
The robber was heavyset and appeared to be in his mid-30s, Marcum said. He was wearing a dark-colored hooded sweatshirt.
Anyone with information is asked to call Lexington police at (859) 258-3600.
