A large gathering at Dunham Park in Sioux Falls on Sunday afternoon, August 25, 2024, ended with the death of 29-year-old Joshau Antrell Allen Jr., a Black/African American man. Multiple callers reported gunfire around 4:21 p.m., and officers found Allen in a parking lot on the park’s west end; he died of multiple gunshot wounds. Three other people from Sioux Falls were also shot and taken to a local hospital by acquaintances, with some sustaining life-threatening injuries that prompted a temporary hospital lockdown.

Investigators recovered shell casings from different handguns, which suggests more than one shooter may have been involved in the altercation at the gathering. Police said they believe those involved knew one another, but a motive has not been determined. The park was closed temporarily while detectives processed the scene. As of late August 2024, no arrests had been announced and the investigation remains open.

If anyone was at Dunham Park that afternoon or has information about who was involved, please come forward to assist investigators.
