Suspect surrenders after shooting death of autistic man in Bronx park.

A 19-year-old suspect has voluntarily surrendered to law enforcement in connection with the shooting death of Ronell Marte, a 26-year-old autistic man, at Starlight Park in the Bronx. The incident occurred on September 4, 2025, and has drawn significant attention amid ongoing concerns regarding gun violence in the area.

Luis Alberto Lopez Castillo turned himself in at the 43rd Precinct stationhouse on Monday. He faces multiple charges, including murder, manslaughter, robbery, and criminal possession of a weapon. According to police sources, the shooting took place around 2:50 a.m., when Marte was shot in the chest in the park located near West Farms Road and E. 174th Street.

Emergency medical personnel quickly responded to the scene and transported Marte to St. Barnabas Hospital, where he was pronounced dead upon arrival. Marte’s residence was reported to be just a few blocks from Starlight Park, raising questions about the circumstances surrounding his shooting.

In the aftermath of the incident, Lopez Castillo’s background has come to light. He was reportedly homeless at the time of his arrest and has a prior arrest record, including a robbery charge from July in Queens. His arraignment in Bronx criminal court is pending, and further details regarding the case are expected to follow.

The shooting has intensified discussions about gun violence in the Bronx, particularly incidents involving firearms in public spaces. Community leaders and local residents have expressed concerns about safety in their neighborhoods and the broader implications of rising gun-related crimes. Advocates for gun safety are calling for more stringent regulations and community outreach initiatives to address the underlying issues contributing to such violence.

Starlight Park, once viewed as a space for community engagement and outdoor activities, has now become a focal point of these ongoing concerns. As authorities continue their investigation, the hope is that justice will be served for Ronell Marte and that steps can be taken to prevent further tragedies in the Bronx.

As the case unfolds, community members and law enforcement officials remain vigilant, working together to ensure a safer environment for all residents. The ramifications of this tragic event will undoubtedly resonate throughout the community as it grapples with the impact of gun violence and advocates for lasting change.
