A 36-year-old woman was fatally shot outside a Mott Haven bodega.

Police say Shaquana Button was shot in the head around 11:30 p.m. outside the East 149th Street store.

Surveillance video shows the argument inside the bodega that led to the shooting. In it, a man can be seen approaching Button, and the two appear to have a heated exchange, with pushing and shoving. Another angle shows a man stepping between the two arguing. Minutes later, the man arguing with Button exits the bodega but goes back inside. Button was eventually shot outside the store.

Witnesses tell News 12 the fight may have started over a cigarette.

Family and friends gathered outside the store throughout the day Tuesday to add candles to a memorial and pay their respects.

Button's family says she was getting ready to celebrate her 37th birthday on Friday.

Police say there are no suspects at this time, and no arrests have been made.
