On the evening of August 23, 2020, in a Lakewood, Colorado Walmart parking lot, 17-year-old Dillon Clark Wikoff and his 18-year-old brother Damian Michael Wikoff were shot and killed after arranging to meet other teenagers to sell a homemade ghost gun. The brothers, who both worked nearby and often met in that lot during breaks, were transported to local hospitals and pronounced dead.

The meeting was a setup for a robbery. A 17-year-old named Michael Mendoza had recruited other teens to carry out the robbery; during the confrontation both brothers were shot and the assailants fled. Four juvenile suspects were arrested in connection with the killings, including Marqueil Banks, identified as the shooter.
