Photos of the vehicle were taken in the vicinity of Prospect Avenue and East 187 Street. The vehicle was seen fleeing eastbound on East 187th Street and turning left onto northbound Southern Boulevard.

The NYPD says the killing was retaliation for the previous gang murder of 19-year-old Tyquill Daugherty a few days before.
They say a 16-year-old killed in a livery car on Sunday night, Ramon Gil-Medrano, was in turn retaliation for Elliot's death.
Anyone with information is asked to call the NYPD's Crime Stoppers Hotline at 1-800-577-TIPS (8477) or for Spanish, 1-888-57-PISTA (74782).
