Lucardio Kroener, 28, was shot and killed in downtown Denver in the early morning hours of September 28, 2018. Kroener was working as a security guard in Lower Downtown, guarding areas including Larimer Square, and was a father to a young daughter. Around 1:53 a.m. police responded to a shooting near 15th and Market Streets. As officers arrived, Kroener confronted a possible suspect near 14th and Market Streets; a physical struggle followed and Kroener was fatally shot. He was pronounced dead at the scene.

Denver police released surveillance images of a man they believed responsible, described as an African-American male, about 25 to 34 years old, stocky, with braided hair and facial hair, wearing a dark hoodie, who fled on foot with an associate. After an investigation that included public tips, police identified 31-year-old Harrison Hall as the primary suspect; Hall was arrested in Louisiana on December 12, 2018, on an unrelated warrant and was later charged with first-degree murder in Denver. Kroener was posthumously awarded the Bill Daniels Neighborhood Hero Award, accepted by his family.
