A gloating Tayside paedophile taunted his victim from custody and bragged to her mother that he would jump on the girl’s head when he was freed.
The 15-year-old girl and her mother were left terrified and distraught when Brandon Williamson sent them a handwritten six-page letter from Polmont young offenders institution.
Dundee Sheriff Court was told the mother and daughter became hysterical and have since been forced to ramp up security at their home.
Williamson, 20, was detained in December after he admitted having sexual activity with two underage girls in Perthshire.
However, within weeks he had penned the sickening letter, which he addressed and then posted to the mother of one of his victims on March 4.
Fiscal depute Stewart Duncan told the court on Tuesday: “He is serving a sentence and is on the sex offenders register.
“During 2018, they were in a relationship when he was 18 and she was 13.
“He was sentenced to 31 months in December 2019, backdated to July 18 2019, and placed on the sex offenders register for 10 years.
“The girl and her mother were in their home when a letter was delivered.
“The mother opened the letter and saw it was from the accused.
“She began to cry uncontrollably. The girl found her mother in an emotional state. The girl read it and felt physically sick from fear.
“There were six handwritten A5 pages. He gloated about the violence he had previously inflicted on her and threatened further violence.”
Williamson bragged about how early he would be released from his sentence and taunted them about coming to their home within a matter of months.
Mr Duncan told the court the mother, who cannot be named for legal reasons, called in the police to report Williamson’s evil threats.
“They have added security measures to the house because they are worried about what will happen when the accused is released,” he added.
The fiscal depute told the court the Crown was seeking a non-harassment order for five years to keep Williamson away from the family and their home.
Solicitor Paul Ralph, defending, told the court Williamson had completed the original 31-month sentence at the end of last month.
He has now admitted causing fear or alarm on March 4 by sending the letter.
Sheriff Alastair Carmichael deferred sentence for reports and remanded Williamson in custody because he poses a “significant risk of reoffending”.
The non-harassment order will be considered at the same stage.
