In 2026, David McNally, then aged 39, of Trevose Road, Truro, Cornwall, was sentenced to an extended sentence of 16 years at Truro Crown Court after pleading guilty to 12 child sex offences.
The sentencing followed an investigation by Devon & Cornwall Police into predatory behaviour and physical sexual assaults carried out across the St Austell area.
The court heard that McNally targeted young children, subjecting a young girl to repeated molestation and actively manipulating others into sexual conduct.
The prosecution outlined that McNally encouraged and coerced a young child to engage in sexual activity with a boy, instructing the children to touch each other sexually for his own perverted gratification.
On Friday, 4 September 2026, McNally appeared before Truro Crown Court, where he entered guilty pleas to:
- 11 counts of sexual assault on a child
- One count of inciting a child to engage in sexual activity with another child
His Honour Judge Simon Carr highlighted the gravity and manipulative nature of the offences, finding that McNally presented an ongoing risk requiring extended public protection.
The judge handed down an extended sentence comprising 15 years’ imprisonment (180 months) and an extended licence period of one year.
The court also ordered that McNally remain subject to the notification requirements of the Sex Offenders Register for life.
Release Calculation: Under UK sentencing legislation governing extended determinate sentences for serious sexual offences, McNally is required to serve at least two-thirds (120 months / 10 years) of his 15-year custodial term in prison custody before becoming eligible to apply to the Parole Board for early release on licence. Early release is not automatic and is granted only if the Parole Board determines that McNally no longer presents a danger to the public. If released, McNally will remain subject to licence conditions, probation supervision, and monitoring until the expiration of his 15-year term plus the one-year extended licence period in September 2042.
