Police are currently questioning two people after their Dodge Charger matched descriptions of one of the vehicles on the scene.
Trinity, a Lafayette High School athlete, was making a name for herself on the track – according to reports.
Julian Tackett, commissioner of the Kentucky High School Athletics Association, wrote on Twitter: “Shocked to hear of death of Trinity Gay. A life of such potential cut so tragically short. Sympathies to Tyson and entire family.”
Olympic Gold medalist and sprint coach Ato Boldon tweeted: “Condolences to Tyson Gay and his family… 15-year-old girl dies after shooting at Lexington restaurant.”
Tyson Gay was part of the US 100m relay team at the Rio Olympics.
In 2013 he tested positive for a banned substance and was banned from competition for a year.
