Tysean Jahisreal Nelson, 19, was shot and killed late on the night of June 30, 2021, in Dover, Delaware. Police say gunfire erupted about 11:08 p.m. in the 100 block of South New Street near Reed Street, where a group of people had gathered. Officers arrived within seconds, treated the wounded and secured the area. Nelson was found a short distance away in a nearby lot and was pronounced dead soon after.

Investigators later counted dozens of spent shell casings at the scene. Three other people were injured—a 39-year-old man and a 22-year-old man taken to the hospital, and a 40-year-old woman who drove herself to a hospital with a leg wound. Detectives opened a homicide investigation, canvassed the neighborhood for witnesses and surveillance footage, and issued public appeals. Early reports did not identify a motive, and no arrests or suspects had been publicly named.

If anyone saw or heard the gunfire on South New Street that night or has footage that might help investigators, please come forward.
