Detectives are actively seeking tips from the public and have not announced any charges or identified a suspect. Anyone with information is urged to contact the Seventh Squad directly through the contact information listed in the official SCPD press release.
Under New York Penal Law, assault or attempted murder charges involving a firearm can carry significant prison terms depending on the degree charged — first-degree assault with a deadly weapon carries a minimum of five years and up to 25 years in state prison for a conviction. The applicable charges will depend on what investigators determine about intent and circumstances once a suspect is identified.
Broader Impact
The shooting of a minor in a residential backyard highlights ongoing concerns about youth-involved gun violence in Suffolk County communities. Earlier this month, Suffolk Police arrested 39 people on DWI charges over the July 4th holiday weekend, underscoring the breadth of public-safety challenges the department is managing this summer. Anyone with information on this shooting is encouraged to come forward by contacting the Seventh Squad.
