Police in Trenton, New Jersey, said 11 people were shot and two were killed when gunfire broke out during a gathering on Locust Street in the early hours of the event date. The shooting happened around 12:25 a.m. in the 100 block of Locust Street, according to the Trenton Police Department, which has said the investigation remains open and that no detailed account of the sequence of events has yet been released.

The incident quickly drew a large emergency response. Authorities sealed off part of the area while investigators collected evidence, and medical facilities in the city received victims as the situation unfolded. NBC News reported that two people died and nine others were hospitalized after the shooting. Police were still working to determine how many shooters were involved and what prompted the violence.

Witness accounts cited by NBC News described the gathering as a neighborhood cookout or block-style event, with a large crowd assembled before the first shots rang out. One witness said about 150 people were present. The account also suggested there may have been more than one burst of gunfire, but police have not confirmed whether the shooting involved multiple shooters or separate exchanges.

The scene suggested a major discharge of rounds. NBC News reported that investigators placed nearly 40 evidence markers along the ground, indicating a wide area of interest for forensic teams. The scale of the response and the number of markers points to a chaotic incident in a residential setting rather than a targeted attack confined to a single location.

Officials have not released the names of the dead or injured. They also have not said whether the victims knew one another or whether the violence was connected to a dispute at the gathering. Police have not announced any arrests and have not identified a suspect. That lack of detail leaves the motive unclear and means key questions remain about whether the shooting was spontaneous, retaliatory or tied to another dispute.

The immediate human toll, however, is already severe. Two people died, nine others were wounded and the event date has become one more reminder of how quickly a large social gathering can turn into a mass-casualty scene. For Trenton, the focus now is on identifying the victims, locating anyone responsible and reconstructing the moments before and after the shooting.

As of the latest reporting in the supplied source, the investigation was ongoing and police had not provided further information about suspects or a possible motive. The case is likely to depend on witness statements, forensic evidence and any video or digital material investigators can recover from the area.
