The suspect's face is hidden, but his intentions are obvious. Caught on tape, he walks into a small town convenience store and demands money. "He actually stabbed the victim almost immediately when the victim didn't immediately open the safe," said Sheriff John York of Livingston County. The video also captures the victim left on the floor...Later... He and another worker tried to stop his stomach from bleeding with coffee filters. Meanwhile, the suspect took off with two hundred dollars, and the sheriff is warning that another attack seems imminent. "It also makes us nervous there was no money taken, so if the individual needed the money that bad, and he was that violent and aggressive, he's certainly going to strike again," York said. A key clue, police say, could be found in the perps coat. Look at the symbol. Police aren't sure what it is yet, but say it could be a lead. "It's got very distinguished markings on the back of it, we would ask the public to look at it, and if they recognize the coat, or know of anyone who wears a coat like that to call the livingston county sheriff's office," York said. Police say they're looking for a white male who is between 5'8 and 5'10 and has dark hair. They're also very curious about finding that coat. The number to call is 585-243-7100.
