As the nightclub closed in Upper Manhattan early Sunday morning, an argument broke out among a group of patrons, as it sometimes does. But this time, tensions escalated, and shots were fired, leaving one man dead and another hospitalized.

The police found a 33-year-old man shot in the groin and a 31-year-old man shot in the chest outside a garage adjacent to the nightclub, Tette on Post Avenue in Inwood, not long after the club closed at 4 a.m.

The 31-year-old man, identified by the police as Ernesto Santiago of the Bronx, was pronounced dead at Montefiore Medical Center in the Bronx. The other man was taken to St. Barnabas Hospital in the Bronx, where he was in stable condition on Sunday.

The garage and auto repair shop, Autorama Enterprises Inc., extends onto 10th Avenue, and blood stained the sidewalk where the two men were found.
