Alfredo Romero, 33, was working as a bartender at a Greenwich Village pizzeria on March 14, 2007, when a disguised man entered and opened fire. Romero was shot multiple times in the back and died at the scene. The shooter was identified as 42-year-old David Garvin, who investigators believed acted out of anger over being repeatedly ejected from the pizzeria and the firing of a friend who worked there.

After killing Romero, Garvin fled into the neighborhood. Two unarmed auxiliary police officers, Nicholas Pekearo, 28, and Eugene Marshalik, 19, pursued him and confronted him; they forced him to drop a bag that contained another handgun and about 100 rounds of ammunition. Garvin then opened fire on the officers, killing both. Plainclothes police later intercepted Garvin; after he shot at them, they returned fire and fatally shot him. No arrests were made because the sole suspect was killed.

Did anyone in Greenwich Village see the shooter entering the pizzeria or can provide more detail about the moments before Romero was shot?
