The mother of Noah Donohoe has rejected a psychiatrist's report that concludes her son took his own life while struggling with a low mood and his sexuality.
The 14-year-old went missing during a bike trip from his home in south Belfast on June 21 2020.

His body was found in a north Belfast storm drain six days later after a major search operation involving police and members of the public.
A post-mortem examination found that the St Malachy's College pupil had died as a result of drowning.
His family is currently locked in a campaign to establish the circumstances of his death.
A coroner has upheld a PSNI application to use Public Interest Immunity (PII) certificates to withhold sensitive information from the teenager's inquest.
A report into the circumstances of his death reveals new details about the teenager's final social media, internet and text activity, along with his interest in psychologist Jordan Peterson.
It has been claimed by investigative journalist Donal McIntyre that the last message sent by Noah was to Peterson's Instagram account and that the PSNI have been unable to access the response.
It is also claimed Noah spent his last days trawling biblical references and advice on how to ward off Satan.
Noah's mother said her son had no difficulties with his sexuality.
"Noah was brought up around same-sex relationships and couples, and so the idea he would have struggled accepting whatever his sexuality was is inconceivable to me," he said.
"To suggest this would be a factor to 'trigger' Noah to consider suicide shows the little understanding the expert had into who Noah was as a teenage boy.
"Noah had no issues of sexuality. That is never something Noah would have hidden," his mother told the Sunday World.
Ms Donohoe added that her son would never have felt "shame" and was brought up to "embrace everyone's individuality regardless of colour, religion and preferences towards how they live their life as long as they don't harm another person by doing so".
It is reported that of the friends and teachers interviewed by police none suggested the teenager had issues around his sexuality.
The un-named author of the report has drawn on witness statements, testimony from family and friends, forensic reports, CCTV, medical reports and maps.
The report does not take the view that Noah's death was a result of concussion, drugs or drink or an accident.
It does conclude that suicide is a possibility.
It is reported that in the days before his death Noah was reading a book written by Peterson and that his mother contacted a school pastoral team to suggest that his mood was down.
He later texted a friend writing: "Ask yourself are you truly happy with the things in your life."
A friend later said that days later he was 'calmer' and focused all conversation on the book he was reading.
