A man has pleaded guilty to killing his mate who died from a heroin overdose after a drug-fuelled bucks' night in Sydney.
Mr Wood died in a Sydney hotel after taking heroin with Gray for the first time during another friend's bucks' night.
Gray, who injected and then tried to revive Wood, was charged after a Sydney inquest.
Mr Wood's widow reportedly told the inquest she did not want any charges to be laid against Gray.
He will face a sentence hearing on April 26.
