Austin-Saddington even became pregnant during their relationship, though she later lost the baby.
Even after Trengrove was transferred to a different prison, she continued visiting him—this time using a false name.
Trengrove, from Camborne in Cornwall, had already been serving a 13-year sentence for rape and sexual activity with a child dating back to 2013 and 2014.
He was given an extra two years and three months on top of his original sentence for his role in the relationship.

Her probationary period was also extended due to suspicions she was getting too close to two other prisoners.
Trengrove later told police they had sex between 30 and 40 times inside one of the prison workshops.
Prosecutor Robert Bryan read aloud some of Austin-Saddington’s messages to Trengrove, in which she referred to him as “the one”, told him she’d love him “til my last breath”, and described him as her “reason for living”


In March 2023, Trengrove was transferred to HMP Channings Wood in Devon.
While he was there, Austin-Saddington sent him intimate photos. However, prison staff intercepted the images before they reached him.

“She is very ashamed and upset. You are not sentencing the woman who committed these offences, she’s a very different woman now.”

“Before this he was a good prisoner, working hard towards the earliest possible release. He knew what he was doing, his heart ruled his head.”

Austin-Saddington pleaded guilty to misconduct in a public office, as well as to bringing a mobile phone into the prison facility.

He also confessed to having a phone in prison and using it for “unauthorised transmission of images or sound.”
