Murray's parents, in breaking their silence on Sunday, confirmed that Murray died of suicide.
"We have spent the last 24 hours trying to come to terms with the fact that our son is gone. It's surreal that we not only have to admit it to ourselves, but that we also have to acknowledge it to the world. It's a nightmare," they said in a statement.
"We have so many questions that have no answers. But one," they continued. "Was Grayson loved? Yes. By us, his brother Cameron, his sister Erica, all of his extended family, by his friends, by his fellow players and - it seems - by many of you who are reading this. He was loved and he will be missed."
"We would like to thank the PGA Tour and the entire world of golf for the outpouring of support. Life wasn't always easy for Grayson, and although he took his own life, we know he rests peacefully now."
RIP.
Condolences to family and friends.
