A birthday party that included a party bus ended in gunfire on the night of June 29, 2024, in Grand Rapids, Michigan. Police were first called for reports of shots around 12:20 a.m. near Ardmore Street SE and Thelma Avenue SE; officers found four shell casings but no victim at that scene. About 3 a.m., Jeremy Parnell, 35, was discovered by his sister in his car with a gunshot wound to the chest. He was taken to a hospital and later died; his death was ruled a homicide.

A Grand Rapids Police Major Case Team investigation developed witness accounts that identified 38-year-old Ronald Armour Jr. as a suspect. One witness said they saw Armour arguing with a friend, then produce a gun and shoot Parnell, and later identified Armour in a photo lineup. Court statements from Armour’s brother described hearing shots, firing a warning shot, and then seeing Armour punch someone while holding a gun; the brother said Armour claimed Parnell had hit him with a gun. Armour has denied firing a weapon, saying he only used his arms in self-defense before leaving.

Anyone who witnessed the party, the bus stopping near Ardmore and Thelma, or the moments just before or after the shots is asked to come forward with information.
