The day after a man opened fire at a Collierville, Tennessee, grocery store, killing one person and wounding 13 others before turning the gun on himself, local police conducted an impromptu news conference to identify the perpetrator.But instead of saying the suspect’s name out loud on that sunny morning in September 2021, Collierville Police Lt. David Townsend held up a yellow piece of paper with the name “Uk Thang” and the birth date “10-17-91.”
