The man even went on to sleep with his granddaughter and became a father to her child as well.
Trigger warning: The story contains details of incest, sexual abuse that might be distressing to some readers.
A man named Tim Colt is accused of creating the "world's most inbred family" after he slept with his daughters and allowed his sons to do the same on their "incest" farm.
The father reportedly had seven children with his wife, June, but he then went on to father more children with his daughters.
The incestuous family was reportedly living in "very dirty and hazardous" conditions, while the children were also seen wearing "dirty clothing." Authorities first came to know about the family after one of the younger girls went to school and told a friend about what was going on at home.
"My sister is pregnant and we don’t know which of my brothers is the father," the young child reportedly said, and this eventually led to an investigation as the police got involved, according to The Sun. All the children's identities remain concealed and the names used are pseudonyms given by the court.
Investigations found that Tim began raping his daughter, Betty, from when she was 12-years-old. Apart from the 13 children Tim had with Betty, he also had four children with his daughter, Rhonda, and even had a child with his granddaughter, Raylene.
While Tim formed incestuous relationships with his daughters, his son Charlie also had his own sexual relationships with his sisters on the side. Charlie openly shared a "marital bed" with his younger sister, Martha, who reportedly had her own five children fathered by Tim, Charlie, or her other brother.
During the trials, the court also heard about how Petra, one of the children born to Tim and Betty, was sexually abused by her uncle/half-brother, Frank. According to the Daily Mail, Frank is Tim's son as well as Betty's brother, and he was found guilty of sexually assaulting his niece/half-sister, Petra.
While speaking to the police, Petra told them she had never been to school and said, "all my aunts, uncles, and cousins have been sleeping together."
In order to avoid the locals becoming suspicious of all the incest, pedophilia, and the neglect going on in the Colt clan, the family would often move around as they lived in Australia. But the police eventually found them living in poor conditions, where the children slept in tents and struggled to speak proper English. There was also no running water, electricity, or toilets in the remote area where the family was living, according to Daily Star.
Although Tim passed away in 2009, his children faced a number of charges and now, the New South Wales Children's Court has allowed the full details of the abuse to be made known to the public by using pseudonyms for the family members, according to Daily Star.
Members of the Colt family had around 80 charges against them originally, and these included incest, child sexual abuse, indecency against a child, and perjury. But many of the charges were dropped along the way.
One of the investigators, Peter Yeomans, who was part of the Colt clan case, said the revelations that came out were "like nothing I've ever seen."
