Stephen Gately's family are reportedly hiring a private investigator for a fresh probe into the tragedy - five years on from his death.
The Irish Sun on Sunday reports that the move comes as the family battle the singer's husband Andrew Cowles over Gately's two million euro estate.
The 33-year-old Dubliner was found slumped on a couch while holidaying in Majorca in October 2009.
Officials ruled he had died from an undetected heart condition.
The family say that neither Andrew nor a man called Georgi have ever fully explained what happened on the night of his death.
