Tracey Leigh Brock, 20, was shot and killed in her home on Altsheler Place in the Okolona neighborhood of Louisville, Kentucky, on Friday, March 25, 2016. A 2012 Tapp School graduate and former Siemens employee, Tracey was the mother of a young daughter, Adrianna Leigh Brock, and was remembered by friends as a devoted parent.

The man identified as the perpetrator was her live-in boyfriend, 24-year-old Stuart Cox. A neighbor saw a silver car speed away from the house immediately after the shooting, chased by a small black dog; Cox was driving that vehicle. Kentucky State Police later located Cox’s car near Bowling Green, attempted a traffic stop, and pursued him after he refused to stop. The chase ended when Cox lost control and crashed; he was taken into custody and charged with Tracey Brock’s murder.

Does anyone who knew Tracey or the couple have information that could shed light on what led up to that night?
