Summary:

Jean Bradley, a 47-year-old businesswoman, was murdered by an apparently motiveless stabbing in Acton, London on 25 March 1993. The case made headline news due to a dramatic chase of the killer by a witness and because it was the second unexplained stabbing of a woman in west London in the early 1990s following the murder of Penny Bell in 1991. The murder remains unsolved.

Vital Statistics

Circumstances of Offense:

On Thursday 25 March 1993, Bradley parked her BMW car as usual in the morning in Carbery Avenue, and after finishing work she travelled home from Green Park to Acton Town station on the Piccadilly Line, arriving at Acton Town at 7:20pm. On route to her parked car in Carbery Avenue she stopped off to buy some cans of drink, and another commuter reported walking past her in Gunnersbury Gardens on her way to her vehicle. As she was about to get into her car a man suddenly and randomly attacked Bradley, causing her to scream and attract attention from residents and passers-by. She had been stabbed eight times in total and the eight-inch long weapon was believed to be either a butcher's knife or a carving knife. She had cuts to her hands where she had tried to fight with her attacker and grab the knife. Passers-by quickly came to Bradley's aid, but attempts by paramedics to revive her failed. A passing carpenter came face-to-face with the killer during a confrontation before pursuing him for over a mile as he ran from the scene, with the attacker being last seen walking up Buckland Walk towards Acton High Street.

Additional Details:

Bradley was a 47-year-old businesswoman who lived in Crowthorne, Berkshire with her boyfriend, teacher Nicholas Osbourne. She specialised in helping businesses move to new premises and her office was located on New Bond Street in London, 30 miles from her home. Prior to this role, she had worked as an air stewardess for British Airways and on the Queen's Flight. The murderer, described as a strange individual, was noted for wearing a peculiar sou'wester hat and had been carrying the knife he used to repeatedly stab Bradley inside a black bag. Patrick Cunningham, a 35-year-old carpenter who directly witnessed the assault while driving nearby, confronted the attacker, who then fled, prompting Cunningham to pursue him on foot for approximately 1.5 miles before losing him near the Prince of Wales pub at the corner of Raglan Close and Church Road. The killer took his hat off, revealing to the witness that he had jet black hair. He was also wearing a 3/4 length cream Parka coat and the witness reported him being "definitely" flat-footed. A piece of plastic from the bag the attacker had wrapped around the weapon was recovered from the murder scene. It had a distinctive logo on it, had the brand name "Narcissus" on it. The bag was traced to a manufacturing company in Ayrshire. It was discovered that the bag was used by a health food shop and a photographic company in Fleet Street but was no longer manufactured. A £20,000 reward was offered for information leading to the capture of the killer, and a mobile police station was set up on Ragley Close by where the murderer was last sighted. On 28 August 1993, 5 months after the murder, unemployed 39-year-old Francis "Frank" Marnell of Downside Walk, Northolt was charged with the murder. The news of this charge was reported on Crimewatch in September, with it being revealed that two locals had originally brought police attention to the individual. Marnell had a history of mental illness, regularly had bouts of psychosis and had problems with drugs. The carpenter who had chased the killer and gone face-to-face with him picked out Marnell at an identification parade, later testifying at court: "The minute I walked through the door he caught my eye". Marnell's defense highlighted a verified alibi: he had been with friends, including Joan Brown, at a flat in South Acton from 6 p.m. to 10 p.m. on March 25, 1993—the time of the murder—placing him elsewhere during the attack. The magistrate discharged the case late on November 10, 1993, leading to Marnell's immediate release without conviction. No further charges were brought against him in connection with Bradley's murder. In 2008, after the conviction of Robert Napper for the murder of Rachel Nickell on Wimbledon Common in 1992, it was reported that detectives would investigate Napper on possible links to the Bradley murder, as well as to the murder of Claire Tiltman in 1993 (which he was later proven to have not committed) and the murder of Penny Bell. However, no links were found and Napper does not match the descriptions given by the witnesses who saw and confronted the killer.
