Kevin Park (27) launched a murderous attack on the toddler while he was babysitting her in Kelty on Easter Sunday.

At the High Court in Glasgow he was given a life sentence by judge Michael O'Grady QC who told him, “In reality, no sentence I can impose can truly reflect the sheer awfulness of what you have done.” Park battered the tot's head off a wall at least twice, punched and stamped on her and prosecutors believe he may have also used a broken pool cue in the violent and sustained attack.

He also grabbed or pinched the ears of tiny Madison, who weighed 13.3 kilos and was 90.5cm tall, causing horrific bruising.

Her skull was fractured and she suffered internal bleeding and tearing to her liver. In total she had 65 separate injuries.

Judge O'Grady told Park, "It is the misfortune of those of us who practise in these courts to see and hear of, day after day, the dreadful things that human beings can do, one to another.

“But even by those awful standards what you have done is wicked beyond all imagining.

“A child in your care looked to you for comfort, protection and probably even love. And, instead for some reason quite beyond comprehension, you inflicted upon her a callous, cruel and no doubt terrifying death.

“It is said so often – because it is true – no sentence that I can impose can change anything for Madison and those who loved her and from whom she has been taken."

He continued, “The question of when you will be released – if indeed you are ever released – is not a matter for me. That will be a matter for the Parole Board."

As the jury of nine men and six woman delivered their verdict, finding Park unanimously guilty of murder, members of Madison's family shouted “Yes.” Her mother, Ann Marie White, sobbed in the public benches.

Park showed no emotion.

As he was led away to start his sentence there was a shout of “Evil bastard.” Advocate depute Jennifer Bain, prosecuting, told the court that Park had 38 previous convictions including a number for violence.

At the time he carried out the murder, Park was Ann Marie White's boyfriend and had recently moved into her home at 61 Croftangry Road in Kelty. They had been dating since November 2013.

He was babysitting Madison while her mother went to a friend's birthday celebration in Cowdenbeath.

Miss White told the court her daughter was a happy child and when she left the house at 2.30pm that day Madison was laughing.

She added, “She was hyper, but she was fine... jumping on the bed, laughing.

“She had been trying to put my make up on as I had left it on the bed.” Just three and a half hours later Madison was lying fatally injured after being attacked by Park.

A woman in a nearby garden who was playing with her grandsons said she heard a child's piercing scream just before 6pm.

At 6.15pm Park dialled 999. The operator who spoke to him and the paramedics and police described him as unemotional and not interested in the condition of Madison.

One police officer even said that Park was more interested in rolling a cigarette.

Madison was rushed to hospital and died from her appalling catalogue of injuries at 10.50pm.

Forensic experts who examined the house found two indentations on the hallway wall at 149cms and 165cms.

On one of these indentations one of Madison's blonde hairs was found and in each indentation there was a large amount of her DNA.

Park did not give evidence. He denied causing the horrific injuries to Madison and claimed she had injured herself before lunchtime on a treadmill and then fell off a bed which collapsed as she jumped on it at 5.15pm However pathologists said that the injuries suffered by Madison to her head and abdomen would have resulted in her very quickly lapsing into unconsciousness and she would have been unable to walk, talk and eat after them as Park claimed she did.

He said it was only after 6pm that he noticed her lips had turned blue and she was unconscious. Park said that minutes earlier she had been watching a cartoon and eating chips.

But the jury did not believe his version of events.

Judge O'Grady told the jury, “This was a deeply distressing case. You have been required to see and hear things no sane person would ever wish to hear.”
