Five-year-old Laylah Petersen was killed on the evening of November 6, 2014, in Milwaukee, Wisconsin. She was sitting on her grandfather’s lap inside his home near 58th and Fairmount when multiple gunshots were fired into the residence from outside. One bullet struck Laylah in the head; she later died at a hospital.

Investigators say the shooting was a case of mistaken identity and an act of retaliation. Earlier that day a man had been acquitted in a homicide; Arlis Gordon, whose half-brother had been the victim in that case, and Carl Barrett decided to shoot at the home of the acquitted man’s girlfriend but went to the wrong address. The two men opened fire while Paul Farr drove the getaway vehicle.

Authorities arrested three suspects: 23-year-old Arlis Gordon, 20-year-old Carl Barrett, and 24-year-old Paul Farr. Gordon and Barrett were identified as the shooters and faced homicide-related charges; Farr was charged with harboring or aiding a felon. Does anyone have information about Laylah, her family, or that neighborhood on November 6, 2014?
