A Dorset couple have pleaded guilty to drug and money laundering offences.
Grant Putman, 33, and Brooke Marshall, 35, from Wimborne appeared at Bournemouth Crown Court on 3rd February 2026 following an investigation by the South West Regional Organised Crime Unit (SWROCU).
The couple admitted to being concerned in the supply of cocaine, ketamine, and cannabis, as well as money laundering.
Putman also pleaded guilty to possession with intent to supply heroin and possession of an offensive weapon.
SWROCU officers, along with Dorset Police, arrested Putman and Marshall in August last year at their home.
Officers seized considerable quantities of drugs including approximately one-and-a-half kilos of cocaine, 400 grams of heroin, two kilos of cannabis, 500 grams of ketamine, LSD, cannabis gummies, and hundreds of illegal disposable vapes.
Weapons and approximately £20,000 in cash were also recovered.
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 Bournemouth Crown Court for sentencing on 24 March 2026.
