Moy believes the council should have done more to monitor his son’s killers.
He added: “I truly believe this could have been prevented and I will do everything I can to make sure another family doesn’t go through this.
“Nothing can bring Kayden back. I’m not looking for excuses, I’m looking for answers and to find the person who is also partially accountable for Kayden’s death.
“All I want now is answers from this.”
Weeks after the killers were jailed Jay Stewart posted a video online from jail in which he appeared to boast about stabbing Kayden.
The video, filmed in a cell in HMP Polmont and posted on Snapchat, showed Stewart topless, masked and rapping about the killing – claiming he will act violently again once he is released.
In August, Cole Turley – the only of the three to plead guilty to murder – lodged an appeal against his life sentence.
Meanwhile, the first minister said he was “incredibly grateful” to Kayden’s parents for meeting him earlier this week.
Swinney added: “To lose a child in such horrific circumstances is unthinkable and Kayden’s entire family continue to be in my thoughts as they show such immense strength in the face of this tragedy.
“The justice secretary and I listened carefully to the points Kayden’s parents made, particularly around reoffending and the dangers of carrying a weapon.
“Where there are lessons to be learned and potential policy legislative changes that the government can make, we will consider those fully.”
The first minister pledged to update Kayden’s parents on all the points that were discussed and said he would be happy to meet them again.
