A jealous boyfriend has been jailed for life after he fatally stabbed a man he believed to be seeing his girlfriend.
After receiving a fatal wound to his chest, Mr Hipperson staggered into Kings Road where he collapsed in front of school run parents and children.
The attack happened shortly before 4pm on May 17, 2020 and Mr Hipperson died three days later.
Muldowney was jailed for 29 years at the Old Bailey on Friday for the “senseless” and “tragic” murder.
Emlyn-Jones, prosecuting, had told the court that Mr Hipperson was attacked after his killer flew into a jealous rage after the pair saw each other in a busy part of Richmond in broad daylight.
He said: “Tim stood up and said, ‘All right Ollie?’. Muldowney’s response to that was to say to Tim, ‘Think you can f*** Bobbie?’, a reference to Muldowney’s long-term girlfriend.
“As Chris Rosser looked on, Muldowney made three or four punching motions towards Tim Hipperson’s upper chest. It was only when Muldowney moved away that Chris Rosser realised that they were not punches because Muldowney was holding a large knife, with a serrated blade, and had used that knife to stab him.”
The court has heard that the victim had a drug addiction and knew his killer.
Judge Shani Barnes said on sentencing Muldowney: “It is quite clear that this was a sad and tragic case. Tim Hipperson, as we have now heard, was a loved son, brother, friend and no doubt partner throughout his life. He was a man inflicted with a Class A drug addiction which he had repeatedly tried to rid himself.
“There can be no doubt that there are many who mourn and will mourn the tragic senseless loss of his life.”
“We saw you in full flight and what it showed to me was that you are a man who is unpredictable, that can be erratic and you can flare in a moment from being calm at a 100 miles an hour to flying to rages.
“The timing and location of this was horrendous. You couldn’t have chosen a worse location or timing. This was an area in public where there were a lot of people in the middle of the day and there were children around.”
