Rapist John Robertson snared by 'agony aunt' letter
A man has been convicted of raping two young girls and sexually abusing two others after a victim's relative read an unsent letter to an agony aunt.
John Robertson committed the offences at an address in Kilmacolm, Inverclyde, between 1990 and 2002.
The letter was found in 2002 but Robertson was not charged until 2011 after other victims had come forward.
At the High Court in Glasgow, sentence on Robertson was deferred and he was remanded in custody.
Temporary judge Michael O'Grady QC also placed him on the sex offenders' register.
The judge told Robertson: "You have been found guilty of an appalling course of conduct, years of preying on vulnerable young women time and again.
"Your behaviour blighted their childhood and haunted their adult years."
The court heard that the note, which was written by one of Robertson's rape victims, was found by a family member in 2002.
The letter stated: "For the last seven years John Robertson has sexually abused me. I am ashamed and embarrassed. Can you help me."
When the case came to court, the victim who wrote the letter, now aged 26, told advocate depute Jane Farquharson, prosecuting: "I can't remember how many times I was raped."
The woman added: "I thought that it kind of happened to everybody and once I realised it didn't I thought I should have said something sooner, but I didn't know how to stop it."
Another victim, who was sexually abused by Robertson, said that she "just froze" while he touched her inappropriately.
A further charge of rape was found not proven against Robertson.
Robertson had denied all the charges against him and claimed his victims were making up lies in order to claim compensation.
