West Indies cricketer Gayle tweeted on Monday: "Such sad news to hear. My condolences to his family & friends. Adrian St John was the captain of the academy. #Sigh."
Donovan Miller, programme manager for the Chris Gayle Foundation, was quoted as saying by the BBC on Monday: "I'm really finding it hard to come to terms with it, how someone could do something like that to such a lovely person."
"He wanted me to support him to go to the Caribbean and to kind of push hard with his cricket."
