Spanish police continue to investigate if Michael Grant struck by a car but do not believe it caused his death.
Medical examiners have found no evidence pointing to the 45-year-old’s death being related to the injuries police believe he suffered when he was knocked over by a car.
Further tests are now taking place at a specialist lab in Barcelona to try to determine why he collapsed near Magaluf’s Punta Ballena party strip in the early hours of Monday morning.
Despite finding no apparent link between the suspected traffic accident and his death, a police investigation into the events leading up to the tragedy is continuing.
As well as knee and leg injuries believed to have been caused when he was hit by a car, Mr Grant had scratches and a cut to his back with glass still inside.
Detectives are still analysing CCTV footage from cameras in the area near to where the holidaymaker was found dead for any clues.
Mr Grant, who was on holiday with his wife Leanne and at least two of their four children and other families from Ireland, collapsed in Martin Ros Street close to Punta Ballena around 4.30am on Monday.
He had reportedly taken a wrong turn and become separated from other members of his group after spending the afternoon by his hotel pool before going out.
They were staying at the four-star Sol Katmandu Park and Resort in Magaluf which describes itself online as a popular hotel for families with young children.
A Civil Guard spokesman said on Monday before the post-mortem: “This death does not appear to be crime-related in any way but the autopsy will be key to determining what happens next.”
A well-placed source close to the investigation said yesterday: “The injuries the holidaymaker had were not life-threatening and this investigation is neither a murder or homicide probe at this stage, nor do we expect it to become one.
“But we are looking into the hours leading up to his death because something has happened that needs to be properly explained.
“There are still a lot of unanswered questions we need to try to get to the bottom of.”
