Sadistic cold-blooded killers unmasked: Women hellbent on inflicting pain who tortured and beat Sheffield man to death pictured for first time

The women who tortured and murdered a Sheffield man in his own home have been pictured for the first time.

Yesterday, jurors took just two hours and 35 minutes to find Zoe Rider, 36, and Nicola Lethbridge, 45, both of Fraser Drive, guilty of the robbery and murder of Stephen Koszyczarski on August 9 last year. The monstrous duo tortured Stephen and filmed some of the attack.

During the trial at Sheffield Crown Court, jurors watched the footage which featured the pair taunting Stephen while they robbed and attacked him. Part of the footage was played during the opening in April, and in it, they could be heard hurling sickening abuse at defenceless Stephen.

One said: "Dirty, f****** wrong 'un...Having his f****** balls cut off. Where's the knife, where's the scissors gone? Little f****** n**** that abusing little girls aren't you Steve?"

During the video, one of the women was seen to be wearing cream joggers. These were later identified and found to have a small amount of blood belonging to Stephen, and both Rider's and Lethbridge's DNA on the waistband.

Prosecutor Andrew O'Byrne KC told the court that Stephen, 60, lived alone at his flat in Fraser Drive, Sheffield, and was described as a "collector". He said on the day of his murder, he had gone to a café and had spoken with the owner there, who he knew. The woman was said to be concerned about Stephen who seemed to be "running short of money".

Mr O-Byrne said: "During the course of the conversation, he complained he wasn't getting much sleep because people in his block were making a lot of noise and disturbing him." It was said the woman offered to give Stephen £55 and although he was reluctant at first, he eventually took it.

It was heard that Stephen was captured on CCTV footage on his way home, but at 11.20pm that night, he pressed a button on a lanyard that activated an alarm used for assistance for those with health issues. Mr O-Byrne said: "He spoke to an operator and asked for assistance. He told them he had been attacked and was bleeding."

The court heard Stephen was taken to hospital but died on August 11. Mr O-Byrne said a pathologist who carried out a post-mortem examination on Stephen's body said he "died as a consequence of what he describes as a sustained and blunt-force physical assault and haemorrhage of the skull".

It was said Stephen had injuries to his head and neck, bruises to his ear, eyes, cheeks and lips. He had also suffered bruising to his chest that were "most likely caused by kicks". Mr O'Byrne described the assault on him as "sadistic".

During the trial, Rider and Lethbridge turned on each other, blaming the other. Following the verdict, Detective Chief Inspector Tom Woodward, leading the investigation for South Yorkshire Police said: “Stephen was described as a quiet man. Although he had a close circle of friends, he kept himself to himself and just went about his business. He didn’t cause any problems or hurt anyone and his death was callous.

“Lethbridge and Rider had not only subjected Stephen to mental torture and physical abuse but they humiliated him during the attack wrongly accusing him of being a paedophile which was simply not the case. I am pleased with the jury’s verdict and the fact that these two will now spend a significant amount of years in prison.

“The community has been a huge support throughout our investigation, and I would like to thank those who showed bravery, taking a stand against criminals living in their communities, and providing witness statements and evidence. The support of the public, along with the hardworking officers on my team and police colleagues have ensured justice for Stephen.

“Although the guilty verdicts bring comfort that justice has been served, this remains a sad day because it is another reminder for everyone how violence can quickly end a life too soon, which impacts greatly on all those involved, and leaves family and friends with pain and holes in their lives.”

Lethbridge and Rider will be sentenced on June 5.
