In the late afternoon of January 15, 2020, gunfire erupted in the Merle Hay neighborhood of Des Moines, Iowa. Police who responded to a home found four men had been shot — three in a garage and a fourth a few blocks away. Two of the men shot in the garage died: 21-year-old Karyree Henderson, a Black male, and 28-year-old Damiko L. Carr. Two other men survived; Michael Blackwell and Alonzo Kearney were identified among the wounded.

Investigators reported dozens of rounds had been fired, but it was not clear who fired the weapons or what the motive was. Within days, survivor Alonzo L. Kearney was arrested after hospital release on charges of Interference With Official Acts and on unrelated outstanding warrants. In April 2020 another man, Alex Arthur, was charged with Obstructing Prosecution after authorities said he deleted part of video surveillance from the property where the shooting occurred.

No one has been publicly identified or charged with the murders of Karyree Henderson and Damiko Carr; anyone with information is asked to come forward.
