A police dog tracked the scent of a suspected convenience store robber Saturday night and uncovered some telltale pieces, or, more specifically, squares, of evidence.

Whether the evidence was two-ply or one-ply remained unknown.
Lincoln Police Officer Katie Flood said Monday that police are still looking for a man who robbed Kabredlo's Convenience Store, 1445 S. 17th St., with a knife -- and toilet paper wrapped around his head to conceal his identity.

LPD received a call from around 10:30 Saturday night.
The suspect came into the store with a knife and demanded money, according to LPD. He took an undisclosed amount of money from the safe, said Capt. David Beggs.

Beggs said the suspect is a 25- to 33-year-old white male, about 6-foot-2, 180 pounds with blue eyes and a skinny face.
He was wearing a black hat, black sweatshirt and dark jeans.
No one was injured during the robbery, Beggs said.

The suspect left on foot, and Flood said Brix, an LPD police dog, tracked a scent westbound through the alley for about half of a block. The toilet paper was found on the north side of 1612 Washington St., Flood said. But the man remains at large.

Anyone with information is asked to call Lincoln/Lancaster County CrimeStoppers at 402-475-3600.
