Tyler Munday 28

Description

A sex offender already in prison for historical offences against a child has been sentenced to a further six years behind bars after being found guilty of additional offending.

In 2019 Tyler Munday, formerly of Porthleven, was jailed for 12 years for a "campaign of sexual violence”.

At that time he pleaded guilty to 12 offences, committed over two separate periods of time from 2011 to 2013 and then again between 2017 and 2018.

The first period of offences occurred when he was 14 or 15, but another seven offences took place when he was aged 19 and 20.

This year he faced a further three charges against a different victim, dating back to 2011 to 2014, but pleaded not guilty.

However, a jury convicted him of two counts of oral rape against a child under 13 and a further charge of inciting a child to carry out a sexual act on him.

Prosecutor Nikki Coombe told Truro Crown Court on Friday (August 29, 2025) that the victim was of young primary school age at the time, while the defendant was aged 14 to 17 during the period of offending.

Ms Coombe said that following the abuse the victim began self-harming and also attempted suicide on more than occasion.

The court heard that the impact on the victim was ongoing. On one occasion they drank so much they passed out, and upon coming back to consciousness all they could see was Munday’s face.

Before this latest conviction, papers had started to be prepared for the parole board for an application for his release on licence, when he would have become eligible in 2027.

However, Mr Murray acknowledged that pleading not guilty to these offences had “tarnished” that progress.

Mr Murray said a “return to Cornwall is not anticipated” once Munday, now aged 28, is eventually released from prison.

Judge Simon Carr told Munday: “The effect on [the victim] has been devastating. During times she has committed acts of significant self-harm and suicide attempts.

“You have shown little remorse for that, as your lack of guilty pleas indicates.”

He continued: “You have done well in prison. However, your not guilty pleas puts this into context, as they [the prison reports] are [now] not as glowing as they might be, and there’s clearly still work to be done.”

Judge Carr said he had to sentence Munday as a child at time of the offences.

As such he sentenced Munday to a total of six years in prison, to be added on to the time already sentenced.

He must serve two thirds of these six years before being eligible for a referral to the parole board.

Munday has also been placed onto the sex offenders register again, where he was already placed in 2019.
