Happened in Nashville.....maybe 20 years ago. Well respected pharmacist IIRC. His daughter's boyfriend had seriously abused his grandchild. "Dude" was in the waiting room and Grandpa came up and expressed his displeasure. With a pistol.
EDIT.........found it.....
About 11 p.m. on the night of Jan. 9, 1986, gunshots shattered the quiet of this waiting room as a local pharmacist named Charles Jones shot and killed Bobby Gann, a 23-year-old wrecker operator from Hendersonville, as Gann slept in a chair.
Jones calmly handed over his .38 to a bystander, other patient family members screamed, nurses came running and did CPR on the victim, but Gann died from his gunshots.
The events that led up to the shooting garnered Jones a lot of sympathy in some quarters. Jones’ grandson, a little boy named Ryan Reed, was in the Pediatric Intensive Care Unit near death, a victim of beating and cigarette burns, and Jones was convinced that Gann, who was his daughter Angela Reed’s boyfriend, had abused the child. The little boy died the next day.
Charles Jones was convicted of voluntary manslaughter and served a short prison sentence.
