A 23-year-old man, Shane Sanchez, was fatally shot just before 2 a.m. outside his apartment building in the Throgs Neck neighborhood of the Bronx. The shooting happened near the NYCHA Throgs Neck Houses on Sampson Avenue. Responding officers found Sanchez on the ground with a gunshot wound to the chest; he was taken to NYC Health + Hospitals/Jacobi and could not be saved.

Police said an argument occurred before the shooting. Investigators worked at the scene for hours and evidence markers were left on the walkway outside the building. No arrests had been made in the initial reports and the gunman was believed to have fled.

Neighbors described Sanchez as humble, happy, a big baseball card collector and someone always willing to help others. His family was grieving and not speaking with reporters in the immediate aftermath.

Does anyone with information about the shooting or who saw activity near Sampson Avenue that night know anything that could help investigators?
