On a September morning in the Bronx, 80-year-old Marcelino Valerio was shot in the head as he and his wife returned to their apartment on Ogden Avenue after a family party. Police nearby heard the gunshot and responded, but Valerio could not be saved. The family initially believed the attack was random; surveillance showed a person on an electric bike riding around beforehand and appearing to wait near the scene.

Investigators later identified a suspect within the family: Valerio’s stepson, Melvin Java. Authorities allege Java donned a ski mask, lay in wait and carried out an execution-style shooting, then returned to the family home and mourned with relatives. U.S. Marshals tracked Java to Reading, Pennsylvania, where he was arrested and extradited to New York to face charges including murder, manslaughter and criminal possession of a weapon.

Does anyone have information about the events that morning or about the relationship between Valerio and his stepson that could help the investigation?
