Six men jailed for over 100 years in total over the death of man in Derby
Dale Martin was pronunced dead following the attack in Stenson Road
A gang of six men have been jailed for combined total of over 100 years following the death of a man in Derby who was stabbed to death.
The court heard on the evening of Sunday 15th June 2025 Jayden Mannion-Roberts, Keenan Hamblett, Ki Grant-Finlayson, Shaylon McCalla, Kelci Thompson and Kayin Holmes, armed themselves with knives and machetes and hunted Dale Martin down while riding a moped and electric motorbikes.
The group found Dale in a car in Stenson Road, Derby, and dragged him out of the vehicle, with CCTV capturing them chasing him – swinging and stabbing at him and shouts of “kill him, kill him” ringing out – before racing away from the scene.
Dale, meanwhile, staggered away from the scene, before collapsing and being pronounced dead a short time later.
The killing triggered a huge manhunt and eventually led to the arrests of multiple people, including the six who were accused of Dale’s murder.
Following a four-month trial a jury took more than two weeks to convict six men of his killing.
Jayden Mannion-Roberts was found guilty of his murder and has now been jailed for life and must serve a minimum of 27 years before being eligible for parole.
Ki Grant-Finlayson and Keenan Hamblett were arrested just as they were about to board a flight to Tunisia a few days after the murder.
They were both found guilty of manslaughter. Grant-Finlayson was jailed for 18 years, with an extended licence period of 21 years, while Hamblett received a 17 years and six months term.
Kelci Thompson, Shaylon McCalla and Kayin Holmes were also found guilty of manslaughter.
McCalla, who was arrested after flying into Birmingham International Airport, was given an 18-year sentence, with an extended licence period of 21 years.
Holmes was jailed for 15 years, while Thompson was jailed for 10 years.
All but Mannion-Roberts must serve at least two thirds of their sentence before they are able to be released.
Temporary Detective Inspector Chris Wright said:
“The killing of Dale Martin was a planned, sustained, and brutal attack.
“The group had set out that night with the intention of causing Dale serious harm – and they carried out their wishes armed with knives and machetes.
“Dale was pulled from a car, chased and fatally stabbed multiple times.
“All those convicted in relation to this offence were happy to use really serious violence in a residential street, with no concern for the harm they would cause, or the worry they would generate in the community.
“The investigation into this crime would not have been possible without the help of the public and I would like to thank them for their support – their assistance was vital in gathering the evidence to bring those responsible to justice.
“I also want to thank Dale’s family for their support during what has been a long journey to get to court – and then an extended trial which has included distressing information that no family should have to hear.
“Finally, I would like to express my thanks to the investigation team and wider force. The response to this incident covered almost every area of the force – on both a direct and indirect level.”
