Trinity Gay, daughter of former world Olympic sprinter Tyson Gay died on Sunday in a shooting in the US state of Kentucky.
The 15-year-old was struck by a bullet during an exchange of fire between two vehicles in the parking lot of a restaurant, AFP reported. She was taken to the city's University of Kentucky Chandler Hospital and was pronounced dead.
Lexington Police said they have launched a murder investigation into the shooting, which happened at about 4am local time at the city's Cook Out restaurant. Witnesses told police gunfire was exchanged between a gray Dodge Charger and a dark-colored sports car with tinted windows.
Mr Gay, who is from Lexington, confirmed her death to local TV station Lex 18.
"She didn't make it. I'm so confused. She was just here last week for fall break. It's so crazy. I have no idea what happened," Lex 18 quoted him as saying.
Messages of support poured in for Tyson Gay and his family.
"Sending our thoughts and prayers to TysonLGay and his loved ones as they mourn the tragic and senseless loss of his daughter, Trinity," USA Track and Field tweeted.
"Condolences to Tyson Gay and his family... 15-year-old girl dies after shooting at Lexington restaurant," tweeted former Olympic sprint rival Ato Boldon from Trinidad and Tobago.
Trinity Gay was a sophomore sprint star at Lafayette High School, where her father once ran.
"Our hearts are broken this morning over the loss of Trinity to this tragic and senseless act of violence," Fayette County School Superintendent Manny Caulk said in a statement to the Lexington Herald-Leader newspaper.
Tyson Gay, who was part of the US 100m relay team at the Rio Olympics, was tested positive for a banned substance in 2013. He was barred for competition for a year.
