A sadistic killer, who repeatedly stabbed his friend for failing to repay a £20 debt, must serve at least 25 years in prison, a judge ruled.
David Knight carried out a "sadistic and tortured" killing in which his 32-year-old victim Paul Tapley suffered 68 injuries, including 11 stab wounds to his chest and abdomen.
Stafford Crown Court was told Knight (35) repeatedly attacked Mr Tapley for nearly one and a half hours at the victim's flat in Market Drayton, Shropshire, and in a car to a local quarry where his body was thrown out of the vehicle.
Knight, of Rodenhurst Flats, Market Drayton, pleaded guilty to the murder of Mr Tapley in April last year. He was jailed for life and told he must serve at least 25 years before being considered for parole.
The judge, Mr Justice Wakerley, said: "The aggravating physical suffering you inflicted upon your victim is sadism - the pleasure of inflicting pain because you enjoyed the power of inflicting pain and suffering on others."
Dennis Desmond, prosecuting, said Knight "was extremely angry at not getting his money back".
He said Mr Tapley was repeatedly attacked in the car and then "thrown out on the road covered in blood".
"Knight must have presented a frightening sight. He was covered in Mr Tapley's blood. When he was arrested and interviewed he told lies and said that another man was involved," added Mr Desmond.
He said a motorist saw Mr Tapley's body and called the police.
Rex Tedd QC, defending, said: "The best form of mitigation is that he has shown his remorse of the offence with a plea of guilty. It is the single most important feature we have to put forward. The deceased and Knight were occasional drinking partners. He is truly sorry."
