Torture-obsessed woman accused of Don’t F*** with Cats inspired murder ‘knocked BMW engineer, 30, unconscious with a vodka bottle before leaving him to drown in a river’, court hears

A BMW engineer allegedly killed by a woman inspired to kill by the Netflix series ‘Don’t F*** with Cats’ could have been knocked unconscious with a vodka bottle before he drowned in a river, a Home Office pathologist told a court today.

Dr Brett Lockyer told a jury Jorge Carreno suffered a ‘blunt force trauma’ to the back of the head.

He said a vodka bottle ‘used as a weapon’ would have caused the type of injury and bleeding under the skull he found during a post-mortem.

The jury in the trial of cat killer Scarlet Blake, 25, heard that financial records show she bought a bottle of vodka online before the alleged murder.

A red bottle top from a Smirnoff vodka bottle found on the riverbank near Carreno’s body contained traces of DNA from Blake, Oxford Crown Court was told.

Dr. Lockyer gave evidence on the fifth day of the murder trial and said that Carreno (30) had a deep bruise about 2 cm in diameter on the back of his head.

He said the object would have caused bleeding under the skin from ‘the head hitting an object or an object hitting the head’.

Asked by prosecutor Alison Morgan KC whether a vodka bottle could have caused the injury, he replied: ‘A bottle of that type doesn’t break, yes, absolutely not.’

He said the blow could have caused the victim to lose consciousness.

Blake – who has been described as obsessed with torture and violence – was the last person seen with Carreno when they walked the streets of Oxford in the early hours of July 2021.

CCTV footage that captured Blake – broadcast live months before the alleged killing as he put a cat in a blender – saw him lead Carreno to his death.

The engineer’s death was initially thought to be suicide or an accident and remained unsolved for two years.

But after a complex police investigation by Thames Valley Police, Blake was arrested and charged with murder.

Blake, 25, was the last person seen with Carreno as they walked the streets of Oxford in the early hours of the morning.

When police examined her cell phone, they found a collage of nine female serial killers and other images and cartoons depicting strangulation.

The jury at Oxford Crown Court watched a video of Blake strangling a partner before she passed out.

A leopard print bathrobe cord was in the background of the video and Blake took a selfie with that garment before stalking the streets looking for a victim.

Dr Lockyer told the jury a mark found on the victim’s neck could have been caused by a ligature.

He said a broad ligature could have caused the injury, but any marks would have disappeared with the body being in the water for some time.

The jury of five women and seven men heard audio of a cat being killed along with Blake and the woman she live-streamed the gruesome event for the Netflix series ‘Don’t F*** with Cats’ to discuss.

As she killed the rescue pet named Starlet, the New Order song ‘True Faith’ could be heard playing in the background.

Canadian murderer Paul Magnotta played the same song as he strangled cats and posted the videos on the Internet.

He was tracked down by animal lovers and found guilty of murdering computer technician Lin Jun in 2012.

Dr Lockyer said his post-mortem verdict was that Carreno died of drowning with alcohol intoxication a factor.

He said Carreno was almost twice the legal drink-drive limit after drinking with colleagues from the BMW plant in Cowley that night.

He said: ‘Whether the degree of drunkenness Mr. allowed Carreno to enter the water or affect his ability to extricate himself from the water cannot be inferred.’

The pathologist said he ended his initial report by saying his results were based on facts presented at the time, but that if other information came to light, it should be considered.

He was later shown the cat killing video and Blake’s preference for strangulation and was asked to reconsider his original findings, including the possibility of strangulation.

Blake denies murder and the trial continues.
