A cigarette-craving, four-time felon is back behind bars following his arrest Tuesday in the snatch-and-run robbery at a Butler convenience store last week.

Butler police credited online leads in helping them track down 30-year-old Christopher A. Gratzinger.

The defendant, who has no known address, later admitted to the crime, according to court documents, even before investigators got the chance to question him.

Police nabbed Gratzinger after they were called Tuesday to Greco's recycling center on Kittanning Street for a man reportedly “attempting to sell a suspicious amount of copper spool,” documents said.

While in the back of a patrol car, police said, he asked Det. Nathan Shulik why he was in handcuffs. The officer advised him it was due to the incident over the weekend.

“If this is (about) the incident at E-Z Stop,” the defendant replied, according to a police affidavit, “all I did was take a carton of cigarettes.”
