A heartbroken family is still without answers after a much-loved teenager ended his own life.
Police could find no evidence to explain why Callum McKenna made his final, tragic decision, an inquest heard today (December 22).
The 'loving, caring young man' from Droylsden died aged 17 on May 16 - leaving behind family, friends and teachers who still don't understand why it happened.

In a statement read at South Manchester Coroners' Court, Callum's mum Lesley Pinner described her son as a 'joker' and 'loyal', with a 'heart of gold' and a 'cheeky sense of humour'.
She said while he would 'encourage others to do well in life', he was 'quiet and humble'.
Callum was a hard worker who excelled at school, gaining 10 GCSEs at Droylsden Academy, and had a conditional offer to study law at the University of Manchester from September.
In her statement, Ms Pinner said: "He seemed to be doing well at school. He had never been in trouble and never had any issues that we were aware of."
She added: "He studied every day, he even studied on Christmas Day."
The court heard that at around 1.30pm on Sunday, May 16, Callum told his mum he was going for a walk while his parents were going to walk their two dogs - and he asked where they were heading.
Callum shouted 'love you' to his mum as he left. He had left out revision notes for chemistry in his bedroom.
Ms Pinner's statement said Callum had also left his phone at home on charge and went out without a coat.
After it started raining, his mum began calling his friends to find out where he was.
The court heard Ms Pinner heard on social media there had been an incident involving a person on a bridge over the M60 and she became worried.
Ms Pinner's sister contacted the police, before officers arrived at her home to the family he had died.
Callum's mum told the court his friends had no idea why he ended his own life, adding: "They said he was the one that looked after them.
"He was [loved]. But he loved us too."
Police coroners officer Colin Price told the court the force received a 'couple of calls' about someone on the bridge on the afternoon of May 16.
Third-party involvement was ruled out, with Mr Price telling the inquest: "There were a number of witnesses that saw him alone on the bridge."
Mr Price said officers looked for evidence why Callum would have ended his own life, but they were unable to find one.
"We have examined his phone et cetera," he said.
"There's absolutely nothing that he has given to say there is a reason for it - no note left or anything like that - which is unusual.
"We have no reason as to why he has done it."
The inquest also heard a written statement from Callum's GP, which confirmed he 'basically never went to the doctors', and one from Ashton Sixth Form College principal Anton McGrath.
He described Callum as a 'very approachable, friendly student' who was 'popular with students and staff alike'.
Mr McGrath's statement said there had been no concerns about Callum's mental health from his friends or the college's safeguarding and pastoral staff.
He said that following his death, Callum was awarded grades of A* in law, A in maths and B in chemistry for his A-levels, which reflected the 'very good progress' he had made.
A post-mortem confirmed there were no drugs or alcohol in Callum's system. The medical cause of death was given as 'traumatic head injury caused by a fall from height'.
Senior coroner Alison Mutch concluded that 'on the balance of probabilities', Callum intended to end his own life and returned a conclusion of suicide.
She told his parents: "I'm just so sorry that we have met under such tragic circumstances and that I have not met your son.
"Perhaps in a few years when he had become a lawyer, he would have come to court, because he had such an incredibly bright future ahead of him.
"What's clear from all the evidence is that there were just no warning signs that anybody could have picked up on. Of course, that does not make it any easier, in fact I suspect in some ways it makes it even harder.
"I am sure both of you racked your brains to think, 'did we miss something?'. All I can say on the evidence I have heard is that there was just nothing.
"It's so sad that for that moment when he was on the bridge, he just took the actions he took and they have had such terrible catastrophic consequences for him and changed your lives so much as well - and caused you to be in the situation no parent could ever wants to be."
At Callum's funeral in June, Ms Pinner described her son as 'the best in the world'.
She added: "I hope he knew that the world loved him.
"The fact that you went first Callum does give us encouragement that things will be in order when we get there.
"You were a gift from God and we have all been blessed to have had you in our lives.
"We will love you forever and you will forever be in our hearts. You will never, ever be forgotten.
"Thank you for making me a better person."
