A secret recording was the final piece police needed to bring a £2m drug ring to its knees and send the gang to jail for almost 150 years.
Kingpin Colin Jones and his right-hand man David Rawling, both from Merseyside, even helped officers put their associates in jail by openly discussing their illicit business over the phone.
The pair had no idea police were listening in on their conversations, including one to hire a hitman to "do a double one" on a former gang member.
After hearing that officers had warned Lee Murray that his life was in danger, Jones and Rawling were heard on the recording discussing the possible ways they could have found out.
While travelling in the car with another associate, Rawling hangs up the call with Jones and can be heard saying: "Someone's bugged mate, sum'in's bugged all round somewhere.
"Could be this f***ing car."
The recordings led to the demise of the 18-strong cartel which flooded North Wales, England and Scotland with £2m worth of Class A drugs.
On Friday, the gang were jailed for a total of 146 years and nine months as part of Operation Tide – the largest policing operation in North Wales' history.
According to North Wales Live, during three days of sentencing at Mold Crown Court, Judge Niclas Parry said there was an "industrial nature" to their operation.
He said that the gang, made up of mostly members from Liverpool and Merseyside, had caused "incalculable harm" in the area they targeted.
Ringleader Jones, 49, from Liverpool but of no fixed abode, had planned the attack on Lee Murray – also known as Lee Go or Eko – a once trusted member of the County Lines gang who had managed the "Echo Line."
Ill feelings had begun between Jones and Murray in January 2018 and had “clearly reached the tipping point” by June 2019, when his role was taken over by Rawling.
Jones later discovered Murray – who used to be "second in command" – had been pocketing some of his profits.
It was said that Murray had also not been answering calls to take orders for the "Echo Line" – specifically targeting the Connah's Quay area in Deeside and which netted thousands of pounds a day on average.
While the gang were under surveillance, Jones can be heard offering an alleged hitman payment and telling him: "Do a double one lad," which the prosecution claimed referred to a shooting someone twice in quick succession with a gun.
Jones and Rawling then took him on a “reconnaissance mission” and were heard saying “just shoot across” when they saw his victim's car pull up outside his girlfriend’s house.
One can be heard saying: "Before… one digit's rung nine on that thing yer off aren't ya?
"And let's face it, they're phonin' an ambulance first aren't they?”
“Yeah, lots,” the alleged hitman replied.
But before the plan could be carried out, Merseyside Police issued Murray with a threat to life notice.
Within hours, Jones was informed and is understood to have called Rawling, who was heard on the bugged device saying: "They've been to Echo's? Again? What the f***?.
"That's bad that lad. That's bad that, it was only yesterday we were talking about that as well you know.”
"F*** me, that's crazy that you know… Mad one that."
Rawling added: "Someone's bugged mate, sum'in's bugged all round somewhere. Could be this f***ing car."
Jones, described in court as a "shrewd operator" who "rarely got his hands dirty," was jailed for 21 years for conspiring to cause grievous bodily harm to Lee Murray and for conspiracy to supply Class A drugs.
