On the night of May 6, 2018, gunfire broke the quiet in a Haverhill, Massachusetts neighborhood. At about 10:45 p.m., police responding to multiple 911 calls found 40-year-old Jeffrey Larkin, a Caucasian man who lived in Revere and had spent most of his life in Lynn, lying in the street at Emerson Street and Grand Avenue with a gunshot wound to the chest. He was taken to Holy Family Hospital and pronounced dead.

Investigators concluded the shooting was not random. Witnesses said Larkin and the person who shot him knew one another and that an argument escalated into the fatal shooting. Police canvassed the area after the incident and the mayor spoke publicly about the murder.

In November 2018 authorities arrested Carlos Manel Rivera, also known as Chin, charging him with murder; prosecutors said the dispute grew out of a drug deal that went wrong and that Rivera allegedly fled the scene. A 25-year-old woman, Sky Stefanelli, was later indicted on a charge of accessory after the fact.

Does anyone with information about Larkin, the November 2018 arrest, or the events on Emerson Street that night want to come forward?
