Almost two-years-ago, tragic teaching assistant Lindsay Birbeck told her daughter she'd be home by six as she went out for a walk that would change the lives of her family forever.
It was on that walk that 47-year-old Lindsay encountered Rocky Marciano Price, then 16, who pounced on the mum-of-two as she passed, killing her and hiding her body in wheelie bin.
One year after his inexplicable crime, Price was unanimously found guilty of Lindsay's murder and sentenced to a minimum term of 16 years imprisonment.
Now, two years after losing the devoted mum, a new Quest documentary titled Britain's Deadliest Kids: The Murder of Lindsay Birbeck has spoken to her loved ones and Lancashire Constabulary ahead of the anniversary of her going missing on August 12 and her body being found on August 24.
On the 45 minute documentary they cover from her going missing to the present day and it sees them address the gap left in their life afterwards as well as the 'despicable' rumours circulating on social media regarding her ex-husband, according to a report from Lancs Live.
Lindsay's daughter, Sarah, is the first to speak. She said: "She said 'I'll see you at six, love you'. And that was the last time I saw her."
Tim, Lindsay's ex-husband, recalled the moment he met the mother of his children. He said: "I saw her. She was tall, dark-haired, stunning, you know, just everything I liked.
"When she agreed to meet me again, I thought, 'winner'."
They would be married three years after that and have children Steven and Sarah. Although they would later divorce, the documentary talks of how they remained close after the separation.
Sarah said of her mother: "My mum was funny, outgoing, courageous. She enjoyed sport and was very athletic and enjoyed activities - walking, running.
"She was caring, like a mum to everyone. She enjoyed caring for people."
Towards the end of the documentary, Lindsay's family would speak about the moment Rocky was found guilty.
Tim said: "It's like a sense of relief. You knew he'd done it, we knew he'd done it. And we just thought, justice is gonna be served now.
"Because of his age, the minimum sentence was 12 years. But because it was pre-meditated, as in he'd followed the lady before Lindsay, and because of the length of time from her going missing to being found, they class it as aggravated.
"So because of his age, the pre-meditated and the aggravated, he got 16 years minimum. The chances are, he will never step foot out of jail for the rest of his life, which made me feel better."
Sarah said: "We have no insight as to why he's done it. I don't think we ever will."
The family also addressed the rumours on social media that Tim had been responsible or involved in the murder.
Sarah said: "There's a lot of people thinking, on social media, that my Dad's involved with it. Because obviously, they've gone through a divorce and people look at that, and think they must hate each other, but they clearly didn't."
Detective Supt Andy Cribbin, of Lancashire Constabulary, said: "Tim Birbeck was never a suspect in the investigation. We looked at Tim's movements along with other people within there.
"Tim was not there, not present, was elsewhere and we could show that. He was not, and could not, be involved in Lindsay's murder."
Tim said: "The police kept saying to me, 'just ignore them, Tim, they'll go away'. But they do chip away at you and it does hurt you. We've been through absolute hell regarding this and then you've got to deal with these people who are pointing fingers. It's despicable.
"I just want people to understand there's still a family, picking up the pieces and trying to rebuild."
To finish the documentary, an emotional Sarah spoke and said: "I don't think it will be possible to rebuild, because like most mums in most families they are a big person to have in your life. So it's hard not to have her there."
