A sadomasochist has been convicted of murder for strangling a police officer to death during a bondage sex session and then trying to dispose of the body in an acid bath.

Stefano Brizzi, 50, admitted he was inspired by the TV series Breaking Bad as he tried to get away with killing 59-year-old Pc Gordon Semple by dissolving his flesh.

Following an Old Bailey trial, the former Morgan Stanley IT developer was found guilty of murder by a majority of 10 to two after the jury had deliberated for more than 30 hours.

Brizzi, who gave no reaction as the jury delivered its verdict, will be sentenced on Friday, 9 December.

The court heard how the defendant met his victim on gay dating app Grindr and arranged a “hot dirty sleazy session” at his flat near London’s Tate Modern gallery on 1 April.

According to Brizzi, Pc Semple died when a dog leash he had been wearing as part of a sex game slipped.

But a pathologist concluded that while strangulation was a possible cause of death, it would have taken minutes rather than moments, as the defendant had claimed.

In the days after the killing, crystal meth addict Brizzi was caught on CCTV buying buckets, a perforated metal sheet and cleaning products from a DIY store. He then set about dismembering the body and stripping the flesh.

Meanwhile, Pc Semple’s long-term partner Gary Meeks raised the alarm and reported him missing when he failed to return to their home in Dartford, Kent.

Neighbours complained about the stench coming from Brizzi’s flat and eventually called police, who came across “globules” of flesh floating in the bath, bags containing bones and a part of Pc Semple’s head, and pools of human fat in the oven.

Brizzi, who was wearing pink underpants and sunglasses, was arrested as officers realised the enormity of what they had found.

The court heard there was evidence in the kitchen that Brizzi had chopped up the Inverness-born officer with a variety of utensils and may have even used chopsticks to eat morsels of cooked meat.

Following his arrest, Brizzi admitted killing and trying to dissolve the body of a policeman because “Satan told me to”.

During the killing, he said he had turned away a man on his doorstep who had arrived for a sex party organised on Grindr.

Brizzi said: “I was right in the middle of strangling Gordon and I said to him, ‘Look, this is not the right time now, people are falling ill and it's a mess’.”

The Italian also told police that he had “chucked” some of Pc Semple’s body into the Thames and thrown away his police badge and belongings.

A human foot was later found by a member of Thames Mudlark Club near Bermondsey Wall.

The court heard that Brizzi was addicted to crystal meth, which had cost him his job at financial giant Morgan Stanley.

In his home, police found a mask and dog leash with Pc Semple’s DNA on it as well as a copy of the Satanic Bible.

Giving evidence, Brizzi, who has HIV, told jurors of the difficulties of being a gay man brought up in a religious Italian family.

He told jurors Pc Semple died in a “state of erotic bliss”.

His lawyer, Sallie Bennett-Jenkins QC, insisted he was no “monster” and could not have eaten Pc Semple’s flesh as it was covered in chemicals.

Throughout his evidence, Brizzi wept and cried out, “I’m sorry” as he was confronted with what he had done.

He had earlier admitted a charge of obstructing a coroner by disposing of the body. Pc Semple’s brain and other internal organs have never been found.
