His “right hand man” Max Bowler, 31, who had used his home in Carlton Road in Long Eaton as a safe house and “operations hub”, was also jailed for 13-and-a-half years after pleading guilty to conspiracy to supply Class A cocaine and owning a gas-powered imitation pistol.
Dominic’s uncle Alan Hulland, 54, of Main Road, Elvaston, was also convicted of conspiracy to supply Class A cocaine.
Straw said on one occasion a police stop of Hulland’s Audi found 2kg of cocaine on open display in a bag for life on the front seat.
He was jailed for nine years.
Two Chaddesden purchasers were also jailed, Lukas Sankey, 29, of Duffield Road, Derby, for eight-and-a-half years, and Valentino Talic, 31, of Beaufort Street, Chaddesden, for eight years.
Sankey had been awaiting sentence for his part in a separate drugs network in 2019 when he became involved, the court heard.
