23-Year-Old Shirley Man Killed in Sunrise Highway Crash, Police Seek Witnesses

Justin Digiovanna, 23, of Shirley, was pronounced dead at NYU Langone Hospital Suffolk after the 2021 Mazda CX-5 he was driving left the eastbound lanes of Sunrise Highway at Horseblock Road and crashed into a wooded area on the highway’s southbound side at about 3:50 a.m., Suffolk County police said.

Suffolk County Police Fifth Squad detectives are treating the Feb. 21, 2026 collision as a fatal single-vehicle crash and are asking anyone with information to come forward. The incident, listed in police accounts and local reports as occurring in the Town of Brookhaven, resulted in South Country Ambulance transporting Digiovanna to NYU Langone Hospital Suffolk, where he was pronounced dead.

Local reaction surfaced in the Facebook group Our Town, Our Community, Our Home!, where a post headlined “23 year old Dies in single car crash early this Saturday morning” relayed the police narrative of the crash at about 3:50 a.m. on Sunrise Highway at Horseblock Road. A commenter identifying personal ties to the family wrote, “It’s a shit show and how much rather than I tell my family if anything, you rush me to…. I went to HS with the family. One of the worst things about being part of a small town Image 8: 💔…,” reflecting the immediate grief shared in Shirley and neighboring communities.

Reporting from Patch, Southshorepress and other local outlets echoed the police description that the eastbound Mazda left the roadway and ended in the wooded area on the southbound side; all accounts specify the vehicle as a 2021 Mazda CX-5. South Country Ambulance is named in community posts as the transporting agency; official police statements noted the hospital pronouncement but did not include additional medical or coroner details in the excerpts available.

Police statements and the assembled coverage do not provide contributing-factor findings. At this time, investigators have not released information about impairment, speed, mechanical failure, involvement of other vehicles, or charges, and the excerpts reviewed did not include a witness contact number or phone line.

Suffolk County Police Fifth Squad detectives continue to investigate the fatal crash and are asking anyone who witnessed the vehicle leave Sunrise Highway near Horseblock Road or who has dash-cam or surveillance footage from the area around 3:50 a.m. on Feb. 21, 2026 to contact investigators.
