Bride-to-be appeals over stabbing
Christine Rothwell: "He was just the most beautiful person"
A tearful bride-to-be has pleaded for help to find the killer of her fiance, who was stabbed to death six hours after they got engaged.
Christine Rothwell told a news conference at New Scotland Yard on Tuesday: "I can't describe how I feel.
She said her "beautiful" fiance was "lovely, caring and sensitive".
Frequently breaking down in tears, she said: "He wouldn't hurt anyone.
"He had the biggest heart. He was just the most beautiful person."
Argument in the street
Police say Mr Roach became involved in an argument with a youth in a street near his home, when he briefly left the small party with a friend.
During the row, the passenger returned to the parked car, got a knife and stabbed Mr Roach once in the chest.
The killer got back into the car and was driven off at high speed by another man, leaving Mr Roach dying in the street.
He was taken to University College Hospital, central London, where he was pronounced dead.
The driver and passenger of the small dark hatchback were both described as black and aged between 19 and 22. The killer was casually dressed and athletically built.
Detective Chief Inspector Michael O'Keefe, who is leading the inquiry, appealed for any witnesses to call the incident room on 0171 275 4336 or Crimestoppers on 0800 555111.
