Courtney Randles was jailed for laundering criminal money from her drug dealer boyfriend.
Randles “lived in style” in a luxury apartment with her boyfriend Christopher Kenny, sentenced to life for Anthony Duffy’s brutal stabbing in Aintree in May 2014.
In July 2015, Liverpool Crown Court learned how Randles, a council employee, was earning £ 18,000 a year, but enjoying expensive holidays abroad, traveling first or business class on ‘lavish shopping sprees “.
She posed for selfies on transatlantic flights and took photos of bags overflowing with designer items from Juicy Couture in New York City.
Henry Riding, prosecutor, said: ‘When the police searched their apartment, accounts and checklists showed a running balance of around £ 475,000 day to day.
“Some £ 61,970 in cash was stashed in a cavity behind a mirror in their bathroom.”
Text messages revealed that Randles attempted to launder hundreds of thousands of pounds for Kenny in 2013.
Nickleby Close’s Randles Toxteth initially claimed she didn’t know where Kenny’s money was coming from, but later admitted she knew it was drug money.
She pleaded guilty to money laundering, disclosure of personal data without consent and possession of the class C synthetic drug TFMPP.
Randles was jailed for three years and four months.
Cody McNulty was part of a gang that smuggled drugs between Merseyside and Cumbria.
The 23-year-old, from Clifford Street to Birkenhead, helped move drugs in a County Lines operation.
County Lines gangs refer to the growing trend of big city gangs selling drugs in small towns and rural areas and often exploit young people and the vulnerable.
McNulty was sentenced to Preston Crown Court in June this year, after a trial in which she was found guilty of two counts of Conspiracy to Supply Class A Drugs and one Count of concern in the provision of Class A drugs.
Convicting McNulty, Judge Beverley Lunt said: “You accept that you were present on some of these trips. But the evidence clearly shows that you were in the car with two of the main dealers involved in controlled drugs.
“The only possible common sense explanation is bleak. ”
In an earlier trial, McNulty was found not guilty on two counts of arranging another person’s travel for the purpose of exploitation.
She was sentenced to four years and 10 months in prison.
Hayley Murphy has lived a life of luxury funded by drug money from her heroin and cocaine trafficker boyfriend.
Liverpool Crown Court learned how Murphy had spent a five-star vacation at sun-drenched resorts like Cancun in Mexico, Montego Bay in Jamaica, Mauritius and America, with her boyfriend and senior member of a drug gang, Gary Jones.
Murphy, then 32, of East Quay, just outside the city center, lived in a “well appointed” apartment and regularly splurged to buy designer clothes and shoes.
She took on the role of money launderer for a Class A drug gang, which was jailed for a total of 109 years in December 2017.
Boyfriend Gary Jones was sentenced to 15 years in prison for conspiring to supply Class A drugs.
Simon Parry, prosecuting, said the couple’s lifestyle was “extravagant”.
They took income from a tanning studio and other businesses, but Murphy claimed she had no knowledge of the large sums of money being transferred to her account due to her boyfriend’s illegal activities.
Deposits totaling £ 49,000 were transferred to Murphy’s account, mainly from Liverpool, but other amounts were sent to him from locations in both Edinburgh and Leith in Scotland.
Murphy was given a 15-month suspended sentence for two years and 160 days of unpaid work.
Victoria Galloway was part of a Widnes-based gang behind drive-by shootings in Speke, Whiston and Huyton.
Galloway, then 32, and her boyfriend Smith, of Brookdale Road, Widnes, were both jailed in June 2016, leaving their four-year-old daughter without both parents.
When police seized a device from Galloway, they found videos of the masked gang’s reckless behavior on scrambler bikes.
At a trial in April 2016, she told the jury that she felt “sick” when her legal team showed her pictures of Smith with a gun resting on his underpants.
When questioned by police, Ms Galloway said she “was not playing gangsters”.
However, prosecutors said she lied to her partner, saying he was injured when he fell from a dog cage and “was not blind to what was happening.”
She was convicted of conspiracy of firearms and conspiracy of cocaine.
Smith was jailed for life with a minimum of 12 years, while Galloway was sentenced to 12 years in prison.
Mum Vanessa Stansfield hired powerful cars for a county drug gang that was embroiled in a turf war with Liverpool criminals.
The eight-man gang, armed with a machete, sword and scaffolding pole, broke into a house in Kilmarnock, Ayrshire, and savagely attacked two drug addicts inside the property.
The two drug addicts trapped in the house were seriously injured in the attack.
Vanessa Stansfield, 28, got involved in the operation through her boyfriend, who drove drugs north of the border.
She appeared before Manchester Crown Court for sentencing in May this year.
Henry Blackshaw, prosecuting, said Stansfield hired a BMW and Audi in his name, which were used by the drug gang.
In a “basic advocacy” document, Stansfield said the cars were not rented solely for the use of drug dealers.
She also traveled to Scotland in May 2017 with her boyfriend and stayed in a hotel in Glasgow, when police jumped and seized around £ 5,000 of heroin and crack cocaine.
His DNA was found on the sock in which the drugs were stored. The sock was thrown away during a police chase.
Stansfield, who lives near Dowson Road, Hyde, pleaded guilty to aiding another person in committing an offense, namely supplying Class A drugs.
Describing Stansfield as a “capable and caring mother,” Judge Richard Mansell QC said: “I will not sentence you to jail given your limited involvement and the absence of previous convictions.
She was sentenced to an 18-month community ordinance, including 20 days of rehabilitation activity.
