On the morning of June 1, 2018, 45-year-old Hyun Kim was shot multiple times inside an Uber on Interstate 25 near the South University Boulevard exit in Denver. Kim was a passenger; the driver, 29-year-old Michael Hancock, shot him during an altercation in the vehicle. A witness called 911 shortly before 2 a.m. to report that an Uber driver had shot his passenger after the passenger allegedly tried to attack him. Police found Kim with multiple gunshot wounds and he was pronounced dead at the scene; an autopsy recorded six gunshot wounds and a high blood alcohol content.

Hancock was arrested and charged with first-degree murder. At trial his defense said he acted in self-defense, while prosecutors argued the shooting was deliberate and pointed to the number of shots fired. A jury ultimately found Hancock not guilty of first-degree murder and acquitted him of all charges.
