Pakistan Cricket Board chairman Nasim Ashraf received an email by Bob Woolmer in the hours before his murder confirming his retirement from international cricket coaching.
Woolmer had decided to stand down after Pakistan were eliminated from the World Cup following a shock defeat to Ireland.
He was found unconscious in his room at the Pegasus Hotel in Kingston, Jamaica, last Sunday and local police have since launched a murder investigation.
PCB chief Ashraf told Sky News: “It was the email of a man who had been deeply hurt. He said that the boys gave it their best to the last minute.
“In that email he had shared some of his thoughts, he told me that he was hanging up his boots and retiring from international coaching.
“However he told me that he would continue to be involved in cricket at the grassroots level.”
