Paedophile Paul Degenhart abused four children in Sheffield between the 1980s and the early 2000s and was given a 34-year extended prison sentence in December.
Degenhart, formerly of Raeburn Road, Sheffield, groomed and abused the victims, including by introducing one of them to drugs.
Sheffield Crown Court heard he took a vulnerable boy from London to Sheffield before he moved on to raping him with ‘devastating physical and psychological’ consequences.
In October this year, the 48-year-old, who by this point had moved to Cherwell Close, Brimington, Chesterfield, Derbyshire, was convicted of 33 offences and remanded in custody after a trial.
The jury unanimously found him guilty of four counts of rape, two of a serious sexual offence, one of attempted rape, 20 of indecent assault and six of indecency with a child.
Degenhart had two relevant and old previous convictions.
He was told he must serve a custodial period of 31 years followed by a three-year period on licence.
Degenhart was added to the sex offenders register for life but was not made subject to a sexual harm prevention order.
Brock Playforth was one of three men jailed for their roles in the killing of a Rotherham dad after a fight broke out at the end of a football match .
Danny Dix, 38, was punched and kicked in the head after two groups of men began brawling with each other in Bridgegate in Rotherham town centre. He died from his injuries in hospital a week later.
Brock Playforth, 26, of North Anston; Kyle Beech, 27, of Maltby; and Liam Green, 23, of Maltby, were found guilty of manslaughter in March 2020 following a three-week trial.
Playforth was also found guilty of attempted grievous bodily harm and Beech was also convicted of affray. Green and Playforth had admitted affray at an earlier hearing.

A Sheffield United football shirt encouraged a young sexual assault victim to come forward, after remembering that her attacker, James Furniss, had supported the team.
The victim, from Derbyshire, told her mother that she had been indecently assaulted after seeing the Sheffield United shirt on the TV, Derby Crown Court heard in July 2020.
The court heard that Sheffield man James Furniss, 32 at the time of his conviction, had sexually assaulted the girl who was under the age of 13 at the time, before slapping her and telling her she was “naughty”, DerbyshireLive reports .
She told how she had been sexually touched by Furniss years before. He had then slapped her and told her she was naughty.
Furniss then disappeared for more than two years before walking into a police station to hand himself in.
Judge Shaun Smith QC jailed Furniss for three years and nine months, with an extended 12-month sentence.
Furniss, of Birklands Avenue, Handsworth, Sheffield , has no previous convictions and pleaded guilty to one count of indecent assault of a girl aged under 13.
Thomas Joshua Bird
Sexual predator Thomas Joshua Bird left his victim traumatised and was seen stalking another woman on the morning of the attack.
CCTV footage showed Bird driving into Fairburn , Selby, North Yorkshire, on June 18, 2020, passing a lone woman and then parking near to the nature reserve.
The 30-year-old from Knottingley could be seen changing into dark clothing before following the woman on foot.
Detectives were able to trace this woman and discovered that she had stopped to speak to a fisherman by the Ings.
It is believed that Bird may have intended to attack her but was disturbed by the fisherman’s presence.
Instead, he returned to his car and changed out of the dark clothing.
He then drove away towards the scene of the attack where he again changed clothing.
Another woman in her 60s, who was walking alone beside the A1246 between Fairburn and Holyrood Lane was then approached by Bird, pulled to the ground and sexually assaulted.
Bird was jailed for 12 years with an extended six years on licence on January 15 at York Crown Court.
He was found guilty of two counts of attempted sexual assault, sexual assault, and failing to provide the police with the PIN to access his phone during the investigation.
Following the trial in November, sentencing was adjourned to allow time for the Probation Service to fully assess the risk Bird posed to the public.
Taking this report into consideration, the judge handed him the extended sentence.
Bird has also made subject to a Sexual Harm Prevention Order and will remain on the register of sex offenders.
Convicted criminal Jordan Ratcliffe had his eight-year prison stay extended for squirting urine at a prison guard.

Teen refugee Debesay Teklehaymanot threatened a woman and two men with an axe and forced them to kneel as he stole bank cards and car keys.
The 19-year-old hit one of his young victims with the axe as he went on a three-day rampage around Sheffield in August 2020.
A judge branded his robberies as “cold-blooded” as he stalked each of his victims and took their belongings late at night while the streets were quiet.
Judge Sarah Wright said that despite his young age, he showed maturity beyond his years.
She said: “Over the course of three days in August last year you committed three sets of almost identical offences of following and threatening lone members of the public with an axe and taking property from each of them.
“On each occasion, you clearly targeted your victim as a young person on their own at night when the streets were quiet.
“You have threatened each of them with an axe and stole from them leaving them frightened and shaken.”
Teklehaymanot, of Ellerton Road, Sheffield, was sentenced to 10 years in prison with an extended licence period of four years last week.
Sexual predator Christopher Hartley used Tinder to find his teenage victims and then lure them to secluded spots and raped them.
The 22-year-old was jailed for 20 years for violently raping two girls he had met on the popular dating app.
He has been branded a “dangerous sex offender” for his horrific crimes, in which he forcibly grabbed both girls, aged 16 and 18, by the neck before attacking them.
Both girls feared they would die.
Hartley, of HMP Doncaster, met his victims on Tinder and lured them to isolated locations before attacking them.
In June 2018, Hartley asked his 16-year-old victim to join him on a dog walk near his home in Adwick-Le-Street, Doncaster.
He then asked her to have sex with him but, when she refused, he got her in a headlock, forcibly squeezing her neck before raping her.
A year later, in June 2019, Hartley picked up his second victim in his car and drove her to an isolated area in Derbyshire, before raping her while holding her around the neck and pushing her.
Following an eight-day trial in November, Hartley was found guilty of seven offences including rape, sexual assault and attempted strangulation to commit rape.
He was sentenced to 17 years in prison, with an extended licence period of four years in December 2020.

Mark O’Flanagan left a woman with severe head injuries in a drink and drug fuelled attack and was jailed for more than nine years.
The 46-year-old launched the assault on his 45-year-old victim in October 2019, leaving her with a fractured skull and bleed on the brain.
The crime was exposed when he woke a neighbour in Hazel Avenue, Auckley, in the early hours of the morning by banging on a window shouting: “She’s dead, phone an ambulance.”
The beating he inflicted was so severe the woman was left bleeding extensively and barely conscious.
O’Flanagan, who was charged in the days after his arrest, refused to comment on any of the questions put to him in interview by South Yorkshire Police.

The Judge also ordered a five-year extended licence period – in her words “to protect the public from serious harm”.
Sentencing O’Flanagan at Sheffield Crown Court Her Honour Judge (HHJ) Sarah Wright remarked that he had “blighted the lives of others forever” with his actions. Addressing him, she said: “Your brutality caused physical and psychological harm. She will live with this, physically and cognitively for the rest of her life.”
