A healthcare assistant has been jailed for smuggling cocaine and ketamine into a prison where she worked.
Megan Woodham, 30, of Wigan, was sentenced to six years after being found guilty of conspiracy to supply cocaine and ketamine by smuggling it into HMP Risley in Warrington, Cheshire.
Daniel Doran, 32, and Kelsey Higgins, 26, were also convicted of conspiracy to supply Class A drugs following a two-week trial at Liverpool Crown Court.
Doran, of Kirkby, was jailed for 15 years on Tuesday, while Higgins, of Bootle, received 13 and a half years.
The investigation was in connection with a previous conviction of John Butler, 27, who was found in possession of 10kg of cocaine with an estimated value of £1 million.
Merseyside Police stopped a black Volkswagen car being driven by Butler carrying the drugs in January last year.
He was jailed for eight years in February after admitting possession with intent to supply Class A drugs.
Valerie Doran, 54, also of Kirkby, Merseyside, was found guilty on 15 December for money laundering and is due to be sentenced on 20 January.
Detective Sergeant Peter Sloan said: "This was a complex investigation which has developed from the arrest of Butler and a subsequent investigation resulted from that stop check.
"Organised crime is hugely damaging to our communities, often involving intimidation, violence and creating fear and it is these criminals who run 'County Lines'.
"Criminals involved in organised crime have no thought for anyone other than themselves, and their criminal intent and greed."
