Morrison was described as a sexual predator
A fake forensic scientist from Greater Manchester who gave bogus evidence at hundreds of court cases has been convicted of raping three young girls.
Gene Morrison, 51, had denied 33 sex offences covering a 30-year period. He was found guilty of 14 charges by a jury at Minshull Crown Court.
The girls came forward after he was exposed as a fraud and jailed in 2007 for posing as a forensic expert.
Morrison, who is already serving five years, will be sentenced in December.
He was convicted of three counts of child rape, six counts of indecent assault, four counts of engaging in sexual activity with a child and one count of perverting the course of justice. All the victims were aged under 16 at the time, the court heard.
Described by the prosecution as a "sexual predator with a particular interest in young girls", he used his regular visits to his local church to meet and then manipulate several of them between the late 1970s and 2007.
He slapped one schoolgirl over her buttocks with a belt if she made any mistake when forced to read out lengthy passages from the Bible, the jury was told.
Prosecutor Neil Flewitt QC said Morrison was a superficially charismatic man who infiltrated the lives of children for the purpose of satisfying his own warped sexual desires.
Morrison said his religion was the "guiding light in his life".
He told the court: "We all have weaknesses. It is a matter of how you progress from that."
Mr Flewitt retorted: "You move on from one young girl to another, that is what you do. Your sex drive was the driving force in your life as well as your Christianity."
His victims came forward after he received a five-year jail sentence in February 2007 for posing in courtrooms as an expert investigator.
He was convicted of 22 counts including deception, perjury and perverting the course of justice after he carried out forensic work up and down the country while totally unqualified.
Morrison tricked judges, barristers, solicitors and police into believing he was qualified in forensics when he left school with no qualifications and downloaded sham degrees from a fictitious US university.
