During the unprotected sex, the girl became pregnant and she tried to take her own life and had a miscarriage.
However, she was too scared to make a formal complaint until September 2014.
Salt, of Malton Grove, Tunstall, denied a string of sexual offences but was convicted of two charges of rape, three charges of indecent assault and one offence of indecency with a child after a trial.
In a moving statement, his victim said the abuse has ‘ruined her life totally’. She added: “I tried to kill myself. All of what happened in the past has resulted in me hating myself.”
Judge Paul Glenn told Salt: “When the jury convicted you, your past finally caught up with you.
“The jury found you guilty of two charges of rape. You were also convicted of offences of indecent assault and indecency with a child.
“The sex was unprotected. I am satisfied she became pregnant. She took an overdose in an attempt to kill herself and procure a miscarriage.
“It was not until September 2014 that she made a formal complaint to the police.
“During her oral evidence it became very obvious just how damaged she is. I have seldom seen anyone more upset. She remains in a state of emotional turmoil.
“You have not shown a glimmer of remorse since your arrest in January 2015.”
Salt was placed on the sex offenders’ register indefinitely and was barred from a range of activities involving children and vulnerable adults.
We was prevented from reporting the outcome of the case, which saw a trial held in January, until the conclusion of a trial involving the defendant’s brother, Brian Salt.
The 76-year-old, of Casewell Road, Sneyd Green, was cleared of two offences of indecency with a child in January but was found guilty on Friday of three charges of indecent assault on a male. He will be sentenced after a report is prepared on him by a probation officer.
