A police dog tracked a robbery suspect for nearly a mile through snow early Saturday morning before Crystal Lake police arrested the man.
Crystal Lake police responded to a robbery at the Open Pantry convenience store at 4811 Northwest Highway shortly after 2 a.m. A store clerk told officers an unarmed man entered the business and demanded money and merchandise, police said.
