A June 15, 2024 walk after a birthday party on Milwaukee’s south side ended in gunfire and two teens dead. Fifteen-year-old Isaac Rodriguez-Duarte was among a group of friends near the 900 block of West Manitoba Street when two people on an electric scooter approached. A brief argument escalated and one of the scooter riders produced a handgun and opened fire, killing Isaac at the scene.

Diego Herrera-Mejia, the party’s birthday youth, was also shot and later died at Froedtert Hospital. A third teen, Diego’s 14-year-old cousin Emily Rocha, suffered a non-life-threatening gunshot wound to the thigh and survived. A memorial of balloons, photos and candles was left at the scene.

Police identified a primary suspect and prosecutors charged 17-year-old Moses Xavier Martinez on June 24 with two counts of first-degree intentional homicide and one count of first-degree recklessly endangering safety, all with a dangerous weapon, and sought an arrest warrant. Jurors later convicted Martinez and he was sentenced; the file was closed after sentencing.

If anyone knew Isaac or saw the group that night, what information might help investigators or the families?
