NESTLED under the cover of the Australian Outback, the Colt clan's warped family traditions were tucked away from society for decades.
The brood earned the grisly title of the "world's most inbred family" following four generations of inbreeding while living in isolation.

Tim Colt allegedly raped his own daughters and encouraged his sons to do the same 7
Perverted patriarch Tim Colt ran an "incest" farm where he raped his daughters with his sons and fathered their children.
He and his wife June, who was also a product of incest, shared seven kids - Martha, Frank, Paula, Cherry, Rhonda, Betty, and Charlie.
The women each birthed their own offspring - likely fathered by their own father and brothers, adding more members to the barbarous brood.
Tim allegedly parented his daughter Betty's 13 children, four of Rhonda's offspring, and even his granddaughter Raylene's child, Kimberly.

The monster, who moved to Australia from New Zealand in 1970, headed up the 38-member Colt clan who were forced to live in squalor in a sickening story of incest, neglect, and paedophilia that shocked the world when their story was first revealed.
Authorities Down Under eventually busted the family's revolting and remote camp in July 2012 - after a child's shock admission at school.
The Colt clan's chilling world of rape and incest was only brought down when one of the youngsters let something slip in the playground.
The kids barely attended school, due to the fact they were frequently shunted to different spots across Australia to avoid detection.

But on one of the rare occasions they did make it to the class - which usually came after a welfare visit - one of the kids revealed a hideous secret.
A descendant of the Colt clan was overheard by a fellow pupil discussing the fact that her sister was pregnant.
But the topic of conversation was not of excitement - instead, the girl revealed she did not know which of her brothers was the father.
The innocent eavesdropper reported the stomach-churning conversation, triggering a chain of events that sparked the demise of the Colt clan.
Police launched an official investigation after getting wind of the child's admission, which led them to uncover generations of incest.
Cramped inside run-down caravans and shabby tents, the family were living in squalor without running water or toilets.
The children - found filthy, malnourished, and barely able to speak - did not know how to brush their teeth or use toilet paper.
They were ridden with chronic hearing, sight and dental issues, while one of the young girls was described as having "dysmorphic" features.
Psychological assessments disturbingly revealed the kids engaged in "inappropriate sexual conduct" with one another.
Many of them have now reached adulthood and have shown marked improvement in personal hygiene and health - but they are still overshadowed by deprivations from their childhood.
Some have low-slung ears or misaligned eyes as a result of inbreeding and they look decades older than their calendar age.
Members of the Colt clan were rounded up by cops after their camp was raided and the details of their depravity were uncovered.
THE CULMINATION OF THE COLT'S
Brother and sister Martha and Charlie, who openly shared a "marital bed", were the first to be detained in the swoop.
Their siblings Rhonda and Frank, Betty's children Derek and Raylene, as well as Frank's son Cliff were then arrested.
All of the Colt children were removed and placed in care, as a horrified court ruled there was "no realistic possibility of restoration of any of the children to their biological family".
Three of the late Tim Colt’s daughters have been dragged through court trials, assaulted in prison, and ostracised in communities due to their inbred children – the products of rape and sexual relations with their own father and siblings.
In one Colt trial, Tim Colt's son Roderick was found guilty of raping his niece, who was also his half-sister.
The victim, Petra, was the biological child of Tim and Betty and was also attacked by her uncle Frank in the back seat of his car during a visit to the family farm in February 2010, for which he was convicted.
Betty was given 14 months in jail after being convicted of four counts of perjury, one of lying under oath and perverting the course of justice.
She later received another 12-month sentence after trying to kidnap two of her sons from their foster parents.
Betty was also forbidden from contacting other Colt family members, after she attempted to get in touch with them via Facebook.
Rhonda received a 14-month intensive corrections order which expired in August 2021, according to reports.
Raylene was sentenced to a 16-month ICO for perjury while her brother Derek received a maximum of three years and ten months for incest in 2020.
Charlie Colt - who originally faced 27 charges – was found not guilty on two charges and acquitted, with the balance being withdrawn.
Of the original 80 charges originally levelled against eight Colts – including incest, child sexual abuse, indecency against a child and perjury – many were dropped.

Although eight family members were imprisoned after their 2018 arrest, only half subsequently received custodial sentences.
The once close-knit clan have dipped their toe in modern life by joining social media, but appear just as socially isolated as they were under Tim Colt's control.
