While in police custody for his alleged connection to a fatal shooting near the so-called "Zombie McDonald's" by Penn Station, "person of interest" Vincent Arcona pulled something interesting out of his person. According to a criminal complaint from the Manhattan DA, Arcona was in a police station interview room when he "reached into his buttocks area" and produced a small package containing heroin. Magic.

NYPD Detective Adrian Calemmo says Arcona then placed the heroin on the table in front of him and inhaled it, as one does. Mission accomplished, he then allegedly tossed the packaging on the floor, under the table, where the detective says he later recovered it.

Asked about the packaging, Arcona allegedly admitted that it had previously contained heroin, back when it was up inside his butt. It's unclear if Arcona was handcuffed at the time, nor is it clear if Detective Calemmo was out of the room during all of this or just sitting across from Arcona in rapt silence.

Arcona has not been charged with anything in connection to the fatal shooting yet, but on Saturday he was arraigned on charges of evidence tampering and criminal possession of a controlled substance. He's being held on $25,000 bail.

The suspect in the shooting, Francisco Alsina, 23, was reportedly arrested in Rhode Island on Friday and is awaiting extradition back to NYC. Investigators believe he fatally shot Angel Quiñones, 43, and wounded two others last Monday morning during a dispute over drug dealing turf.
