Shocking video shows a porn star dancing naked while covered in blood moments after he murdered a couple whose decapitated, hacked-up bodies he then dumped at a popular UK landmark.

Yostin Andres Mosquera, a 35-year-old Colombian national, was convicted Tuesday of murdering Paul Longworth, 71, and his partner, Albert Alfonso, 62, in their west London apartment in July last year.

He was convicted largely based on a chilling video captured on a camera set up to record a sex session — but that instead caught him killing the couple and then joyfully singing and dancing while naked and still covered in blood.

“Do you like it?” Mosquera taunts Alfonso at one point as he stabs him, hours after he had already battered Longworth to death with a hammer and hidden his body under bed covers.

Mosquera — a porn star who was staying with the couple — then decapitated and dismembered the men, stuffing their heads in a freezer as he also tried to access their bank details on their computer.

He was arrested two days later as he was confronted about 100 miles away in Bristol while hauling other body parts in suitcases that he dumped at the popular Clifton Suspension Bridge.

“This is probably one of the most traumatic, harrowing murder investigations I’ve dealt with by virtue of that video,” Detective Chief Inspector Ollie Stride said Tuesday.

“The team [has] consumed hundreds of hours of footage, including some of the utmost disturbing and graphic nature,” the lead investigator said. “Those images will stay with all of us for a very long time.”

Mosquera admitted killing Alfonso, but claimed it was manslaughter by reason of loss of control.

But he was found guilty of murder at Woolwich Crown Court in southeast London, where a jury was repeatedly shown the distressing evidence.

“We put serious demands on jurors, in this case more than most,” said the judge, Sir Joel Nathan Bennathan.

Mosquera will be sentenced on October 24.
