Mihn Tina Nguyen, 47, was shot and killed on November 30, 2020, while closing T & N Market, the convenience store she owned with her husband, Khiem Ken Ba Trinh, at 1345 North Grandview Street in Mount Dora, Florida. A masked male gunman with a thin build entered during an apparent armed robbery, forced Khiem back into the store and shot both owners multiple times. Mihn was pronounced dead at the scene; Khiem was airlifted to Central Florida Regional Hospital and died a few days later.

A customer found the victims and called 911. The suspect fled on foot through the parking lot and remained at large. Mount Dora police released store surveillance footage and offered a $10,000 reward for information. In December 2020 police arrested 42-year-old Undrea Dixon on charges of providing false statements and failing to render aid; she pleaded no contest in April 2021.

Anyone who knew Mihn or the Trinh family, or who saw suspicious activity near the store on November 30, 2020, is asked to contact investigators with tips.
