Wimborne pair plead guilty to supplying drugs and money laundering

Grant Putman and Brooke Marshall, who supplied class A and B drugs across Dorset, await sentencing in March.

A Wimborne couple have pleaded guilty to supplying drugs and money laundering.

Grant Putman, 33, and Brooke Marshall, 35, of Old Manor Close, appeared at Bournemouth Crown Court on Tuesday 3 February 2026 following an investigation by the South West Regional Organised Crime Unit (SWROCU).

In addition to pleading guilty to being concerned in the supply of class A and B drugs including cocaine, ketamine and cannabis, they pleaded guilty to money laundering.

Putman also pleaded guilty to possession with intent to supply heroin and possession of an offensive weapon.

The pair were arrested in August 2025 at their home address by SWROCU officers, with assistance from Dorset Police. Approximately 1.5 kilos of cocaine, 400 grams of heroin, two kilos of cannabis, 500 grams of ketamine, hundreds of illegal disposable vapes, LSD, cannabis gummies, weapons and around £20,000 in cash were seized.

DI Pete Walker of SWROCU said: “Both Putman and Marshall were supplying a vast array of drugs in significant quantities which would have undoubtedly made their way to the streets of Dorset. These drugs bring devastation to our communities – fuelling violent crime and anti-social behaviour, as well as serious health risks.”

Putman and Marshall are both due to appear at the same court for sentencing on 24 March 2026.
