On July 1, 2018, 19-year-old Jacky Vue was shot and killed at the 38th Annual Hmong Freedom Festival in Como Regional Park, St. Paul. It is not clear whether Vue was involved in the initial confrontation. He had recently graduated from high school.

Police who were already on site arrested two cousins in connection with the homicide. Court filings say Nougai Xiong, 27, was identified as the suspected shooter and was charged with two counts of second-degree murder; his cousin Yang Houa Xiong, 28, was charged with aiding an offender and led police to where the gun was hidden. Reports state Yang Houa told investigators the cousins had been attacked with umbrellas and threatened, and that Nougai then drew a handgun and fired. Anyone who was at the festival or has information about the fight or the people involved is asked to come forward.
