On the evening of July 19, 2022, 21-year-old Walter Ochoa Jr. of Uniondale was found mortally wounded in Uniondale Park just before 9 p.m. He had been shot in the chest, slashed in the neck, and stabbed in the abdomen, and was pronounced dead at the scene. Police say he had been in the park with another person when three armed assailants cornered them and fled after the attack.

Prosecutors have tied the killing to MS-13, alleging it was retaliatory and that Ochoa was targeted because he was suspected of belonging to a rival street gang. A Hempstead man, 20-year-old Gerson Hernandez, was arrested on second-degree murder charges; authorities say Hernandez and at least two unapprehended co-defendants surrounded Ochoa, with one shooter firing the fatal shot while others slashed and stabbed him. A federal superseding indictment also names several additional defendants and alleges the murder was part of broader racketeering activity.

Did anyone see activity in or near Uniondale Park that night or have information about the people named in the indictment?
