Riley Stonehouse was killed the night of August 28, 2017, after a planned buy in Bakker Park in Sioux Falls to purchase a small amount of marijuana turned violent. He was 17 and seated in the rear of a vehicle when an older teen, Dylan Holler, arrived with two juveniles intending to take the drugs by force. Holler climbed into the car, pistol-whipped the seller, Jayden Eastman, and in the ensuing struggle the handgun discharged twice. Stonehouse was struck in the chest and leg, was taken to Sanford Hospital, and was pronounced dead; police recovered the gun in the park.

Holler was initially indicted on first-degree murder, first-degree robbery, and aggravated assault; a judge denied him bond early in the case. He later pleaded guilty to first-degree manslaughter, and on February 15, 2019, a judge sentenced him to 80 years with 40 years suspended, leaving the possibility of parole after about 20 years, and ordered roughly $44,000 in costs and restitution. The South Dakota Supreme Court upheld the sentence in an opinion filed May 20, 2020.

Are there witnesses or anyone who spent time in Bakker Park around August 28, 2017 who can add details about that night?
