A man has been convicted of murder after Tim Hipperson, from Richmond, named his killer with his dying breath.

Drug dealer, Oliver Muldowney, aged 35, of Richmond was found guilty of murder following a trial at the Old Bailey on Friday.

Muldowney's drugs runner, Jonathan David Nash, 36, of Feltham, was found guilty of two counts of being concerned with the supply of heroin and crack cocaine.

The court heart that Muldowney killed Mr Hipperson with a large serrated kitchen knife in an ambush driven by jealousy.

The stabbing occurred on a Monday afternoon on May 17 last year in Peldon Passage, near King's Road Nursery, which is close to Richmond town centre.

It emerged during the trial that Mr Hipperson and a friend, Chris Rosser, had arranged to buy drugs from Muldowney earlier in the day with the passage set as the pick-up point. Muldowney's runner Nash delivered the drugs.

Once the deal was done, Muldowney arrived to ambush Hipperson, accusing him of sleeping with his partner and stabbing him several times.

Following the attack, Mr Hippsrson staggered into King's Road where members of the public attempted to give first aid and called emergency services.

Mr Hipperson named his attacker as 'Olly', which was captured on the body worn video of one of the first officers on the scene.

In the aftermath of the attack, Muldowney and Nash fled to a flat in nearby Peldon Court where a woman accomplice ordered a taxi to take him away from the area.

Subsequently, the killer tried to buy the silence of Mr Hipperson's friend – Chris Rosser – by offering him drugs and money to leave the area. However, Mr Rosser refused and co-operated with the police.

Over the following two days, police visited nine addresses associated with Muldowney and at one they found his phone wrapped in tinfoil and hidden in a shoebox containing children's toys.

Muldowney was subsequently arrested in a hotel in Reading of May 21, while Nash was found at another address.

Detective Inspector Maria Green, who led the investigation said: "My thoughts are with Tim's family and friends at this incredibly difficult time. Tim may have had struggles in life but he has always been a much loved son, brother and friend.

"In the immediate aftermath of the attack, as he stumbled onto King's Road, he was able to name the man who had stabbed him. He said 'Olly' and this was captured on the body worn video of one of the first officers on the scene. Within days Oliver Muldowney was arrested and charged despite his attempts to evade justice.

"Muldowney was motivated by jealousy and Tim Hipperson paid the price for that jealousy with his life. Muldowney was convinced his partner was seeing other men, with Tim being one of them.

"Determined to avenge his bruised ego, Muldowney killed Tim in an alleyway. He then attempted to bribe Tim's friend, who was a witness to the attack, with drugs and money but it didn't work. He did the right thing and spoke up for his friend."

Both men will be sentenced at a later date.
