Luis Ramos, a 40-year-old Hispanic father of four, was shot and killed following a dispute that escalated on Dudley Street in Boston on March 14, 2015. The shooting happened about 3:45 p.m. near the intersection of Dudley and Brook Avenue after witnesses reported hearing an argument between two men; Ramos was struck multiple times and died after being taken to a hospital.

Witnesses and police said the shooter fled in a dark-colored SUV later identified as a dark gray, blue, or black Mercedes Benz GLK with distinctive chrome trim. The driver was described as a Black or Black Hispanic male. Authorities released surveillance footage of the vehicle and appealed to the public for tips, while Ramos’s family, including a mother and a youngest child who was one year and a half old at the time, publicly pleaded for information.

Despite the early investigation and circulation of details, no arrests were announced and the case grew cold. If anyone has information about the March 14, 2015 shooting or the Mercedes Benz GLK seen leaving the scene, please come forward.
