LEXINGTON, Ky. (WDRB) -- The daughter of Lexington native and Olympic athlete Tyson Gay was killed Sunday morning in a shooting outside of a Lexington restaurant.

The Fayette County Coroner's Office reports 15-year-old Trinity Gay was pronounced dead around 4:30 a.m. at University of Kentucky Hospital.

Lt. David Biroschik with the Lexington Police Department says officers responded around 4 a.m. to the parking lot of the Cook Out restaurant on South Broadway in reference to shots fired.

Witnesses reported an exchange of gunfire between two vehicles -- a gray Dodge Charger and a dark-colored sports car with tinted windows.

A private vehicle took Gay to a hospital. She was then transported to UK Hospital where she was pronounced dead.

Lt. Biroschik says officers were able to locate the Dodge Charger involved and two possible persons of interest were being questioned. Police were still working to locate the other vehicle involved.

According to officials, an arrest was made in connection with the shooting just before 6:30 p.m. Sunday.

Dvonta Middlebrooks, 21, is charged with wanton endangerment and possession of a firearm by a convicted felon. 

The arrest citation determines Middlebrooks was in the parking lot and fire several shots at the time of the incident. 

Around 10:30 p.m. Sunday, Lexington Police said they had arrested two additional individuals charged as part of the ongoing investigation. 

Chazerae M. Taylor, 38, and 19-year-old D'markeo C. Taylor were arrested and charged with wanton endangerment. Officials say they are father and son.

Officials in Lexington also say they have recovered a second vehicle, a blue Ford passenger car, which was described by witnesses at the scene of the shooting.

The investigation does not show that Gay was the intended target, Lt. Biroschik said.

The case has been labeled a homicide.

An autopsy is scheduled for Monday morning, though the coroner's office lists Gay's cause of death as "gunshot wound."

According to a spokesperson for Fayette County Schools, Gay was a student at Lafayette High School.

Superintendent Manny Caulk released the following statement to WDRB News on Sunday afternoon:

"Our hearts are broken this morning over the loss of Trinity to this tragic and senseless act of violence. Please join us in keeping the Gay family close in thought and prayer and supporting the students, staff, and families at Lafayette High during this unspeakably difficult time."

Trinity is being remembered by family, friends and her track coach, who said she was an honor student and star athlete. 

"I have a little girl of my own and it just breaks my heart to even think or fathom the idea, excuse me for getting emotional, but you know just loosing a child, I'm very heartbroken," Crystal Washington said.

The investigation into Gay's death is ongoing. Anyone with information is asked to contact the Lexington Police Department at (859) 258-3600.
