THIS is the callous assassin who smiled in the dock as his fate was read out.

At 38 years old, Mark Fellows now faces a significant chunk of the rest of his life behind bars.

Today, Wednesday, a jury found Fellows guilty of the double murder of Paul Massey and John Kinsella just three years apart.

In the weeks, month and even years after the assassination of Mr Massey in 2015, Fellows lived a relatively normal life.

During these years, detectives had their suspicions but officers didn’t have enough evidence to arrest Fellows.

The 38-year-old worked for a company manufacturing ready meals for supermarkets.

As a sous-cook whose responsibilities included making sauces, Fellows worked the evening shift from 5.30pm to 5.30am at the Greencore factory in Woolston.

But his secret life unravelled when he arrogantly believed he could kill again – and get away with it for the second time in three years.

Fellows was arrested at Manchester Airport as his plane touched down after enjoying a holiday with his girlfriend in Amsterdam on May 30, 2018.

At the time, the 38-year-old had been living in a property in Sandy Lane West in Orford. He had relocated to Warrington sometime between his first and second killing.

Known as The Iceman, Fellows was involved in a gangland feud that spiralled out of control in the summer of 2014.

This resulted in the murder of Mr Massey when the A Team split in two different gangs, turning friends into enemies.

The long-distance runner, who completed the Great Manchester Run in 2015, wasn't going to take anything to chance when he plotted the murder of Mr Massey.

He even used GPS technology on his Garmin Forerunner watch to track his time to the location of the first murder.

Weeks after the death of Mr Massey, Fellows was shot by a gunman in Weaste. The bullet narrowly missed his elderly grandmother.

By the time of the second killing, he had spent another three years enjoying life as a free man.

Detective chief inspector Carl Jones, of Greater Manchester Police, said yesterday: “Mark Fellows is an absolute callous killer to plan, how he did, to murder Paul Massey.

“To go into huge detail and visit the scene, he planned it to the nth degree.

“He moved onto the murder of John Kinsella and used the same tactics, tried and tested.

“That is why we are able to bring the two investigations together so quickly.

“Clearly, he is unfazed by what has happened.”

Mark Baker, detective chief inspector at Merseyside Police, added: “We are under no illusion that the Kinsella family themselves have been handed a lifelong sentence – including John and Wendy’s baby, who will now sadly go on without her father.

“The murders of John Kinsella and Paul Massey were premeditated and brutal.

“No human being, no matter their past, should have to lose their lives in such violent circumstances.

“As a result of their actions, Mark Fellows and Steven Boyle have caused the public to feel unsafe in the St Helens and Salford area for some time.

“We are hoping we can now work alongside our communities to rebuild the trust and security that has been so cruelly taken away.”
