A CAGED killer who knifed a boy to death at a house party while pregnant told lags she was a “man-hater” - while bragging about her callous crime in jail.

Blade fiend Jolene Doherty - one of Scotland’s youngest female killers - was locked up this year after the brutal murder of Conner Cowper, 18, at a flat in Holytown, Lanarkshire.

Last night, a prison source claimed the teen thug, who turned 18 last month, whined that her hatred of men was the reason behind the slaying in April last year.

Doherty was also branded ‘the most hated woman in Scotland’ after a sickening clip of her smacking an autistic boy was uploaded online in social media in 2013, when she was just 12.

Last night a prison source claimed: “Everyone in jail knows who Jolene is because of the video of her beating up an autistic boy when she was around 12.

“The prisoners all hated her when they found out about that, but she somehow managed to wangle her way in with them by giving them fags and telling them sob stories about an abusive ex.

“She was saying she did it to Conner and the other boy because she’s a man-hater and was attacked off her ex-boyfriend.

“Jolene uses the same excuse for everything bad she’s done.

“To be honest, she didn’t seem ashamed of it or like she has care in the world.

“A lot of the girls she hangs about with in jail said she’s a man-hater and that she laughs about the fact that she is.”

Remorseless Doherty — who has a history of violence and carrying blades and was expelled from school aged 11 — was convicted of murder in January this year.

She plunged a blade into her victim’s neck in a savage and unprovoked attack after Conner branded her a “stupid wee girl.”

The vile killer - who gave birth while on remand in Cornton Vale jail - was sentenced to life at a hearing at the High Court in Edinburgh and told she would spend a period of 16 years in custody.

Doherty was branded “highly dangerous and unstable” over the attack when she was just 17.

During the trial Lord Arthurson blasted Doherty for showing “no empathy” to her victim’s devastated family.

Conner’s grieving family had to listen to heartbreaking details of how the yob butchered Conner while high on cocaine and booze.

Last night Conner’s disgusted mum Linda Fraser, 37, told of her pain upon hearing “evil” Jolene’s brags in jail.

Distraught Linda, of Airdrie, will have to face a heartwrenching first Mother’s Day without her only son this weekend.

She said: “Things like this she feeds off of - she’s evil.

“She used this excuse about her ex during the trial but there’s been no insight about whether this has been true.

“She is scum, she took the most precious thing in the world away from me.

“I try and block her out now and concentrate on my boy.”

She added: “I hope she rots in hell.”

Conner’s distraught nana Janet Fraser, 59, also hit out at Doherty’s vile brags behind bars.

Sickened Janet - who was described as Conner’s ‘second mum’ - wept: “She’s hurt every one of us, I’m living day to day and I don’t even leave the house anymore.

“This is just another kick in the teeth - she’s shown no remorse.

“She’s an evil witch and she’s using this as an excuse for what she’s done to our Conner.

“She should never get anywhere near her child because she’s a danger to everyone around her.

“We are living with complete heartache.”

The serial violent thug - who turned 18 last month - was filmed battering a vulnerable boy six years before she murdered tragic Conner.

Horrifying footage which provoked national outrage showed pint-sized Doherty punching the lad in the face five times, while she told him: “I can tell you’re f*****g s******g yourself.”

Disgusted social media users shared the video online before the blonde killer demanded it was removed from Facebook.

Unashamed Doherty later wrote on Facebook: “Haters make you famous.”

Conner’s mum Linda, a kitchen assistant, said: “We were made aware of a video of her years ago battering an autistic boy as pages were made in her name.

“She managed to somehow get it removed from Facebook and Youtube and changed her name on Facebook to Jolene Smith so that people didn’t know it was her.

“The video is absolutely disgusting and shows her for what she really is - evil.”
