AN EVIL teenager has been jailed for life after the "entirely random" murder of a teaching assistant - before burying her in a shallow grave.
Rocky Marciano Price, 17, targeted mum-of-two Lindsay Birbeck as she went for a walk in woodland before killing her and hiding the body in a wheelie bin.
He stuffed her body in a wheelie bin and hid her at the back of a cemetery - before her body was found 12 days later wrapped in plastic bags.
On Wednesday, Price, from Accrington, was found guilty at Preston Crown Court of her murder, exactly a year on from when she disappeared.
As he was ordered to serve a minimum of 16 years behind bars, Linday's heartbroken daughter slammed the killer for his " unforgivable" actions and said "all our lives are completely ruined".
She said: "My mum was a higher level teaching assistant and the irony is she would have taught boys like the defendant and would have tried her best to help him.
"To know now that he murdered her for absolutely no reason is heartbreaking and has not sunk in yet. Not within me or other members of my family.
"The fact that he has made us come to court and listen to every graphic detail of my mum's murder when he could have saved us this pain by pleading guilty is unforgivable.
"All our lives are completely ruined and I don't see how we will ever recover as a family as the void that has been left will never be filled."
Mrs Birbeck left her home in Burnley Road, Accrington, for a late afternoon walk to a nearby wooded area known as the Coppice.
She had invited her daughter, Sarah, 17, and her boyfriend for tea at 6pm, but when she did not return as planned her family raised the alarm.
The killer - who was named yesterday after reporting restrictions were lifted at Preston Crown Court - was taken to the police station by his parents Creddy, 47, and Martina, 39, after his "shocked" teachers recognised him in CCTV released by cops.
Sentencing Price to life, Mrs Justice Yip said today: "The attack was swift and brutal.
"I am sure the defendant lay in wait with the intention of killing a passing woman.
"Why he decided to kill her only he knows. If it had not been Lindsay Birbeck, it could have been someone else. This was the entirely random killing of a stranger."
In an earlier statement, her family blasted Price for his "evil, cowardly behaviour".
They said: "Lindsay went for a walk on a sunny afternoon in August and never came home."
Price, who has a low IQ of 65, was described by teachers as "very quiet" and "pretty much non-verbal".
Lancashire Telegraph today revealed the teen had lived in Accrington with his family including his parents and five siblings.
The teen had tried to claim he didn't kill Lindsay but was offered "a lot of money" by an unknown man to "get rid of the body".
But jurors saw through his lies and unanimously found him guilty of murder at Preston Crown Court on Thursday after just three hours.
Horrifically, the court heard the teen had tried to chop up Lindsay's body and severe force was used to inflict catastrophic neck injuries, possibly through stamping, kicking or kneeling.
A post-mortem determined she died as a result of compression of the neck after her body was found at Accrington Cemetery, Lancashire, in August last year.
Detective Superintendent Andy Cribbin of Lancashire Police, said it was a "despicable crime" that saw the teen attack and kill Lindsay, who was a "complete stranger".
He said: "Throughout the investigation and trial, the defendant weaved a tale of lies and tried to pass the blame onto an ‘unknown man’, who in reality did not exist.
"He has shown no remorse whatsoever for his offending and the devastation caused to the lives of Lindsay’s family and friends."
He said chilling CCTV showed the teen making several trips from Coppice to the cemetery - believing that he was seeing if he could move the mother's body without being caught.
The killer youth, appearing on video link, did not react when the foreman read out the verdicts.
There was also no reaction from his parents at court.
The teenager had pleaded guilty to assisting in the disposal of her body but claimed he played no role in her death.

He claimed he was approached by a stranger who promised him “a lot of money” if he disposed of a body.
A search of his Accrington home had uncovered plastic sheets that were "indistinguishable" to the ones at Lindsay's grave.
Tracksuits and other clothing were also analysed and matched those worn by the youth from CCTV on August 12, 16 and 17.
