Murder victims' fate 'revealed'

Alison Day was strangled with part of her own blouse

The Old Bailey trial of David Mulcahy has heard graphic accounts - based on the statements of convicted serial killer John Duffy - of the three murders he allegedly committed with Duffy. Mulcahy denies 15 counts of murder, rape and conspiracy to rape.

Alison Day

The 19-year-old was Mr Mulcahy and Duffy's first murder victim on 29 December 1985, the trial heard.

Alison was on her way to keep her fiancé company while he was working overtime at a printers by Hackney Wick station.

She was late and he was anxious. As he saw another train arrive, he stopped work and ran on to the platform calling her name.

"She was already dead - raped and murdered about 100 yards away," said Mark Dennis, prosecuting.

Police found her body face down in the adjacent river Lee. Her blouse had been cut into three pieces and used to gag and bind her.

The third piece was round her neck, used as a tourniquet to strangle her, alleged the prosecution.

Duffy was convicted at his trial of her murder, but details of "the full horror of the attack" were not known then, said Mr Dennis.

Alison was the only person to get off the train. Mr Mulcahy grabbed her and Duffy produced a knife, the court heard.

She was manhandled to the end of the platform and down to the river where they took it in turn to rape her, the prosecution alleged.

Mr Dennis said Mr Mulcahy - fearing she could identify them - took out a knife, cut up her blouse and put a tourniquet round her neck.

"He justified the killing to Duffy saying they would be done for attempted murder anyway.

"Moments later, no doubt fearing Duffy's reticence, he told Duffy they were in it together. He told Duffy to take hold of the tourniquet and give it a twist.

"He said they had no choice. It was the right thing to do."

Maartje Tamboezer

The 15-year-old Surrey schoolgirl was killed three months later on April 17, 1986.

She was last seen after school, riding her bicycle to buy sweets from a shop near East Horsley station.

Her badly-burned body was later found in nearby woods with the watch halted at 5.35pm.

Mr Dennis said Duffy said he had agreed go to the area after Mr Mulcahy promised he could "go first" with the victim.

They lay in wait in trees near a path and, after watching her ride past knowing she would return the same way, they tied fishing line across the path to trip the bike up.

After she was raped, Mr Mulcahy turned on her, saying she had been looking at him, and struck her across the head with a stone and she fell to the ground, the Crown claims.

Mr Dennis said Mr Mulcahy tied the girl's belt around her neck and told Duffy: "I did the other one. It's your turn to do this one."

Following the killing Mr Mulcahy allegedly went back to wipe away fingerprints.

Anne Lock

The 29-year-old had just returned from honeymooning in the Seychelles when she was murdered.

She worked for London Weekend Television as a secretary and had been asked to go in on 18 May 1986.

She left her bicycle in the shed at the station in Brookmans Park, Hertfordshire.

She left work at 8.30pm but never returned home.

Mr Mulcahy and Duffy, it is alleged, hid her bike, intending to trap its owner as she went to find it.

"She was seized, led down the railway tracks to a field where she was raped and murdered," said Mr Dennis.

Her badly decomposed body was found two months later in undergrowth.

One of her socks was inside her mouth and the other had been tied round her jaw. An attempt was made to burn her.

"Duffy was acquitted of this murder on the direction of the then trial judge for want of sufficient evidence.

"He has now admitted his involvement in this offence and last year admitted her rape," Mr Dennis told the jury.
