The case made headline news at the time due to a dramatic chase of the killer by a witness and since 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 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.

In 2008, the case returned to the news when there was speculation linking the murder to Robert Napper, who had just been convicted of the killing of Rachel Nickell.

[2] When she first got the job she decided that the best way to commute to work would be to drive half-way in to Acton Town tube station and then get to the London Underground for the rest of the journey.

[2] She and her housemate had specifically decided that the best place to park for Acton Town station was in Carbery Avenue nearby, since it seemed to be a safe street in a respectable area.

On the day she was murdered, Thursday 25 March 1993, Bradley parked her BMW car as usual in the morning in Carbery Avenue.

[2] 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.

[4] After chasing the killer into Gunnersbury Lane the carpenter pursued the man as he ran towards Acton Town station, and a woman in a vehicle who had also witnessed the initial events drove past the pair again, getting a good view of the attacker.

[2][7] Initially it was considered that the only possible motivation could have been a robbery which had gone wrong, but Bradley's handbag was left lying on the back seat of the car she was getting into when she was attacked.

[2] It was suggested that he could have bought his clothes from charity shops, and it was also revealed that many people who had witnessed the chase had not come forward, with the lead detective pleading for them to help catch the man.

[2] 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.

[10][7] It was revealed that a number of people had reported seeing a man matching the description of the killer behaving in a suspicious way in Acton and on trains around west London.

[12][13][14] 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.

[13] Significantly, 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".

[16] Other witnesses (who had not got as close to the man as the carpenter) had picked out other men as the killer in identification parades, and two friends of Marnell claimed he had an alibi.

[26] On 28 March 2013, an episode of Criminologist David Wilson's series Killers Behind Bars: The Untold Story aired that investigated possible links between Napper and the Bradley murder.
