WASHINGTON • Three suspects, including a father and his son, have been arrested over the death of American Olympic sprinter Tyson Gay's daughter, who was caught in a shooting between two vehicles outside a Kentucky restaurant.

Witnesses told police that gunfire was exchanged between occupants of two parked cars - a grey Dodge Charger and a dark-coloured sports car with tinted windows - in a parking lot in Lexington in the wee hours of Sunday.

After the shooting, Trinity Gay, 15, was taken in a private vehicle to a local hospital where she was pronounced dead, Reuters reported.

Lexington Police Department yesterday said 38-year-old Chazerae Taylor and his son D'Markeo, 19, were charged with wanton endangerment in the fatal gunfire.

A third man, Dvonta Middlebrooks, 21, was charged with the same count and a weapons charge. He had fired multiple shots, CBS News reported police as saying.

A fourth man was being questioned and has not been charged.

"She didn't make it. I'm so confused," Mr Gay told the sports editor with NBC-affiliate Lex 18 television. "She was just here last week for fall break. It's so crazy."

Mr Gay, 34, who made his Olympic debut in 2008, won a silver medal with the 4x100m relay team at the 2012 Games in London. He is the US 100m record holder and the joint second-fastest 100m runner of all time, behind Usain Bolt.

Trinity was a rising star on the track team at Lafayette High School, her father's alma mater.
