Murder accused searched for 'fatal blows' online

Yostin Mosquera is accused of murdering both Albert Alfonso (M) and Paul Longworth (R)

Computer searches for the phrase "where on the head is a knock fatal?" were made on the same day a couple were decapitated, dismembered, and dumped in suitcases, a murder trial has heard.

Yostin Mosquera, 35, a Colombian national, denies murdering Paul Longworth and Albert Alfonso on 8 July last year at their flat in London, where he was staying.

On Tuesday, Woolwich Crown Court heard how "hammer killer" was also typed in, and repeated searches were made for chest freezers in the lead up to the killings.

Many of the searches were in Spanish, some used Google translate and were also made while Mr Mosquera was the only person in the house, the jury heard.

Mr Mosquera has admitted the manslaughter of Mr Alfonso by way of loss of self-control.

He is accused of stabbing him in the torso, face and neck during a recorded sex session at a flat in Shepherds Bush on 8 July 2024.

Footage of the moment was played to the jury, with Mr Mosequera repeatedly asking his victim "do you like it?"

At another point he sings and dances in the aftermath of the attack.

He is also accused of attacking Mr Longworth with a hammer earlier the same day, shattering his skull before hiding his body in a divan bed.

The men's partial remains were found in suitcases on the Clifton Suspension Bridge

The prosecution alleges that Mr Mosquera then "decapitated and dismembered" the two men and left their heads in a freezer before travelling to Bristol.

Their partial remains were later found in suitcases on Clifton Suspension Bridge.

Mr Mosquera denies murdering either man, and insists Mr Alfonso killed Mr Longworth.

He told the jury he saw Mr Longworth's dismembered body and decided to copy it.

Mr Mosquera, who does not speak English, first came to the UK from Colombia in June 2024 on the promise of English lessons and financial support from Mr Alfonso, whom he had met years earlier through webcam sex websites.

On Tuesday, it was suggested Mr Mosquera made the ominous search on the morning of the murders because he had already hatched a plan to kill.

Prosecutor Deanna Heer KC said the ambush "probably" happened around the time the curtains were seen closing inside the flat.

CCTV images captured Mr Longworth still alive in the flat window at the time those searches were made about potentially fatal blows to the head

"You closed the curtains at 12.30pm and open them at 1pm," she said.

"I suggest that this is the time you took a hammer and hit Paul Longworth.

"You approached him from behind and you hit him on the head with the hammer. You did so repeatedly."

Mr Mosquera flatly denied the allegation and said: "No".

A white plastic bag which had flaky and dried blood inside it was found to contain Mr Longworth's DNA.

Ms Heer asked Mr Mosquera: "Did you put that bag over Mr Longworth's head before you hit him with the hammer?"

He replied: "No."

Paul Longworth (L) and Albert Alfonso (R) both suffered multiple "defence-type" injuries on their hands, the coroner said

Mr Mosquera has previously told the jury he feared for his own life and believed he was about to be killed when he stabbed Mr Alfonso - who he claimed had already killed his own partner.

He also alleges to have been thinking about the threats Mr Alfonso had made to him and how he had been treated.

Referring to his defence statement outlining how he felt at the time of the killing, Ms Heer told Mr Mosquera: "You thought that your head would blow up like a balloon.

"You could hear the blood pumping in your body and you could hear a constant beep.

"This happened to you a few minutes before you killed Mr Alfonso."

The trial continues.
