A deadly shooting in Bed-Stuy has left three children without their mother.

Police say 27-year-old Nancy Williams was shot once in the chest Friday near a playground at 730 Gates Ave. Witnesses say they heard two men arguing and then someone opened fire as Williams visited a memorial for a rapper who was recently killed.

Williams leaves behind a 10-year-old, 8-year-old and an infant.

Police are still searching for the gunman.
