Anthony Martin, 21, from Coventry, was convicted of murder and robbery, and sentenced to 20 years.
In relation to a fifth defendant from the Coventry area, the jury were unable to reach a verdict on the two charges against him.
Following the sentencing the Senior Investigating officer, Detective Inspector Gregg Dawe commented: “This was a large scale and protracted investigation which resulted in Devon and Cornwall Detectives working closely with their colleagues in the West Midlands and National Crime Agency.
“Key to this investigation was the support and assistance given by members of the public and local businesses whom I would like to thank for their assistance.
“This was a particularly vicious and violent attack. Those responsible were engaged in the illicit supply of controlled drugs and were motivated by money.
“The sentences imposed should send a message and act as a deterrent to anyone involved in the illegal supply of controlled drugs and the violence that is often associated with such crime.”
