THE father of Oisín O'Driscoll has paid tribute to his 'best buddy' following the seven-year-old's death this week.
Oisín was found alongside his mother Sinéad Higgins, 37, at their home in west London on Wednesday December 14.
Police officers forced entry to the house on The Fairway in Ruislip shortly before 11am Wednesday morning following concerns for the welfare of the occupants.
The bodies of the mother and son were found inside the property.
Oisín's father, Shane O'Driscoll, has spoken of his "angel" on social media.
"Thank you for all your support and messages.
"Words cannot express how we are feeling.
"Today it became real when I had the first opportunity to hold Oisin and see his little face.
"My best buddy has been taken from this world and taken from all his little friends.
"He has always been an angel.
"Sleep well my little man. Love Dada."
A post mortem examination started Friday, December 16 at Uxbridge Mortuary.
The cause of deaths were inconclusive, and officers are now awaiting further toxicology tests.
However following the examinations, detectives are satisfied that the deaths are consistent with a murder and a suicide.
A spokesperson for Metropolitan Police added that at this stage of the investigation, no one else is sought in connection with the two deaths.
The 37-year-old mother had lived in London for 16 years and had worked as a nurse for a number of hospitals in the capital.
She later retrained as a medical legal advisor, which was her occupation at the time of her death.
Sinéad Higgins came from a large family of nine children, however her brother and father passed away some years ago.
She described herself as a ‘fun person’ and a ‘proud mama’ to Oisín on social media.
Detective Inspector Dave Bolton, from the Homicide and Major Crime, said it’s likely the deaths “do not involve a third party.”
“The investigation is at a very early stage but enquiries so far lead us to believe there is a likelihood that the tragic events that led to the deaths do not involve a third party.
“We are appealing to anyone who has any information to come and speak with us.”
