Alison Morrison, 45 (centre) was stabbed on her way to work in Harrow, north London, and was taken to hospital but died of multiple stab wounds within hours.
Her neighbour, satellite TV engineer Trevor Gibbon, 48, was later arrested. Residents said the pair were locked in a bitter dispute over a shared driveway (left), and just weeks ago Mr Gibbon's partner, school teacher Maria Perrett, 52, gave neighbours a handwritten letter (inset) saying they had installed a CCTV camera. The victim was a senior manager at consumer organisation Which? and dedicated charity volunteer, and neighbours said: 'This is such a shock'. Police were at the scene of the attack tonight (right).
