Gardaí in Waterford have renewed their appeal for information about the death this morning of Paddy Barry following a robbery at his home in Waterford last week.
While investigations are continuing, Supt Chris Delaney said the preliminary findings of the post mortem examination have been made available to the investigating team.
Supt Delaney told RTÉ the findings reveal no specific evidence of assault. Mr Barry, who was 82, was the grandfather of the magician Keith Barry.
Paddy Barry was seriously injured after a break-in at his home in the Mount Sion area on 16 September.
Mr Barry died early this morning never having regained consciousness after the robbery.
It emerged earlier that Mr Barry contacted the gardaí immediately after the robbery and was able to direct them to his house.
When gardaí arrived they found he had collapsed with injuries to his side and head.
Detectives in Waterford have issued a new appeal for information.
They want to speak to anyone who met or spoke to Mr Barry the week before the robbery.
They also want people who saw anyone acting suspiciously in Mount Sion Avenue, Lower Yellow Road or the Barrack Street area of Waterford around the time of robbery to contact them.
They are also looking for two teenage girls who were believed to be throwing eggs near Mr Barry's home at around the time of the robbery.
They have also made an appeal for anyone with direct knowledge of what happened, including family members and friends of the person or persons who may have been involved, to contact them at Waterford Garda Station.
An 18-year-old man was arrested last Thursday in connection with the incident. He was released without charge and a file was sent to the DPP.
An additional appeal for information in relation to Mr Barry's death has been made by Garda Commissioner Facthna Murphy.
The Commissioner said he is saddened by the death of Paddy Barry and that the death brings into focus the work of gardaí in the community.
He urged the public and anyone with information on the incident which led to Mr Barry's death to come forward.
He said he wants to focus his officers on preventing similar crimes against everyone, including the elderly.
Commissioner Murphy said he understood the death of Mr Barry will cause concern for elderly people, but he said he wanted to reassure everyone gardaí would do all they can to bring the perpetrators to justice.
He said that people know what happened to Paddy Barry and he urged them to come forward with any information they may have.
The Commissioner also passed on his condolences and sympathies to the family of Mr Barry.
The Garda Commissioner said it is only by people assisting gardaí that such crimes will be prevented and eventually solved.
Asked about concerns over garda cutbacks, he said the resources available to him are being used in the most efficient manner possible.
He said visibility and interaction within the community is central to how the garda force will work in the future.
The Commissioner made the comments as he launched the Garda Community Safety Week, which will focus on the community and in particular the elderly.
Age Action has meanwhile urged all communities to review the safety precautions being taken by their older neighbours, friends and relatives in the wake of the pensioner’s death.
Earlier, Keith Barry and his family paid tribute to their grandad.
‘He was a wonderful man, a great father, an amazing grandfather, a doting great grandfather and he will be missed by not only his family but his neighbours and community.'
The Barry family also thanked everyone who sent their wishes, thoughts and prayers.
