A Bowling Green man was one of three people murdered in Louisville on a day intended to spread a message of peace.
The killings took place within hours of each other a day when National Night Out events were held around the country.
37-year-old Ronnie Walker was pronounced dead after being shot in the head around eight p.m.
Police say Walker and another man had gotten into an argument that led to the gunfire.
There have been 45 murders in Louisville this year.
