The parents of Holly were savagely killed in October 1981 with Harold Dean Clouse Junior, 21, and Tina Linn Clouse, 17, discovered after a dog came home with a decomposed human arm.
They had moved from Florida in January 1981 but, according to police, were later found dead as Junior was battered to death and Clouse strangled.
Baby Holly was then given to a church after being left as an orphan and was taken into care.
However Josh Szimhart, who specialises in cults, told The Mail the group involved in handing Baby Holly was in fact ‘Christ’s Family’ who spent years walking through the American south west bare foot.
The family had an infamous past as a convicted drug trafficker named ‘Lighting Amen’ was found guilty of molestering or annoying a child under 18 in 2003.
And just last week, Texas authorities believed a religious group had taken the girl into their care.
Brent Webster, first assistant attorney general, said the group who separated male and female members and were strict vegetarians, could have played a key role with Baby Holly.
It remains uncertain what interaction the group had as Holly’s new identity hasn’t been revealed.
She is thought to be a 42-year-old mother-of-five living in Cushing and was traced 1,000 miles away in Oklahoma where her parents had been killed.
Mr Szimhart said Christ’s Family were one of a number of odd cults that were about in the 1970s as they spent their time in places such as Yuma and Arizona – the country highlighted by police.
The group took the last name ‘Christ’ and lived off charity handouts, food stamps and had blankets as makeshift beds.
Szimhart claims he saw around lots of members of Christ’s Family in New Mexico, in the late 1970s and early 1980s.

He said to DailyMail.com: “There were other Jesus type groups but these people were very distinctive, they said that you should smoke marijuana and they wore the white robes.
“Right away you were curious because they were so distinctive. One of the women squatted down to talk to me. She didn’t have any underwear on. She was very comfortable with that.
“They were not trying to recruit me and attracted people passively through their look and peaceful demeanour.
“A few young people would get curious and find meaning in their words and they’d sign up and a month later they’d be wearing the costume.”
The group weren’t thought to be violent but used the Bible to gain power over people.
Mr Szimhart added: “The leader micromanaged the whole thing – he was narcissistic in his way of interpreting the Bible, combining back to the Earth movement with the Bible.
“He developed this look, the white robes which seems like something from the movies about Jesus with white headbands they tied around their heads.
“Amen used the Bible to gain power over people and promote his grandiose vision of who he thought he was.’
