A satanist who strangled a gay cop from Kent to death during a drug-fuelled sadomasochistic sex session before chopping up the body, dissolving it in acid and eating parts, was jailed for life today.

Breaking Bad fan Stefano Brizzi killed PC Gordon Semple, 59, from Greenhithe, after they met through the gay dating app Grindr for drug-fuelled "hot dirty sleazy" sex on April 1.

After killing the officer, Brizzi dismembered the body, using perforated metal sheets to grate the flesh from the bones, before dissolving the remains in acid over the next few days.

The 50-year-old cooked and tried to eat parts of the body, with PC Semple's DNA found on chopsticks, in a cooking pot and in the oven.

A human bite mark was also discovered on one of his ribs, which matched Brizzi's teeth.

They took crystal meth and played a sex game which involved a leather-clad Brizzi sitting on the officer's face and tightening a leash around his neck.

Brizzi, a former web developer for the bank Morgan Stanley, denied killing him, and claimed PC Semple had accidentally died in a "state of erotic bliss" when the lead around his neck slipped.

But at the Old Bailey last month, the Italian national was convicted of murder.

Brizzi was jailed today for life with a minimum of 24 years for the murder.

He had admitted one count of obstructing a coroner by dismembering the body, which he received a seven year sentence for, to run concurrent.

The court heard it had been confirmed Brizzi had tried to eat part of the body, which was considered an aggravating feature.

Brizzi had argued he only heated the body to help him get rid of it.

Prosecutor Crispin Aylett QC said a doctor had taken an impression of Brizzi's teeth, and found a "close correlation" with the rib marks.

Mr Aylett said: "Mr Brizzi did indeed attempt to eat part of Mr Semple's body."

Judge Nicholas Hilliard QC, the Recorder of London, said he was satisfied Brizzi had tried to eat parts of the body.

He said: "There is evidence that he did also bite into the body, at one point at least. That is the view I would come to."

Sentencing him, he said: "You had been an enthusiastic participant since 2013 of what is called the chemsex scene.

"Your attempts to conceal what happened, and dismember and destroy his body, are terrible features of the case" - Judge Hilliard

"As a result, I am entirely confident that nothing that happened between you and Mr Semple would have shocked you or taken you by surprise.

"I have no doubt, as I said, that there came a time when you went beyond what you had agreed, and you intended to cause him really serious harm. I am sure the facial injuries were deliberately inflicted by you."

He said Brizzi had not tried to call the emergency services, adding: "Your thoughts were for yourself and whether you could get away with it. That is the reason - not panic of any kind."

The regret he now expressed for PC Semple's death had to be seen by his actions "over a number of days to the body", he added.

Judge Hilliard said: "Your attempts to conceal what happened, and dismember and destroy his body, are terrible features of the case."

During the trial Brizzi admitted being "inspired" by an episode of the US TV show Breaking Bad, in which the main character, Walter White, dissolves a rival in acid.

Giving evidence, he said: "I think I was inspired by the idea. I took whatever was there, thinking maybe I can dissolve him.

"And I probably thought of the acid in Breaking Bad.

"How many other ways could I have disposed of a body? I didn't know where to start."

Brizzi flushed the "flabbery" bits down the toilet, and chucked some of the remains, including the organs, in the River Thames.

Excerpts from a victim impact statement from PC Semple's older brother Ronald were read to the court today, which described him as a "Dixon of Dock Green" character.

PC Semple ran several marathons and organised charity events and outings, the court heard.

Mr Aylett said: "He and his family were devastated when the news of Gordon's murder was disclosed, and they still find it difficult with to deal with.

"It was clear he was regarded as something of a Dixon of Dock Green character."

Although he was in a relationship, PC Semple regularly used Grindr to meet strangers for "extreme" sex. Brizzi's tastes were "similarly extreme".

Despite being on duty, PC Semple visited Brizzi at his flat on the Peabody Estate in Southwark, south London in mid-afternoon.

Over the next few hours, the pair used Grindr to invite others round for a chemsex party.

Just one man, known as CD, turned up for the orgy at about 7pm, but only got as far as the front door of the block of flats.

On April 4, a neighbour knocked on the door to complain about the smell, and Brizzi told him he had been "cooking for a friend".

The next day, Brizzi was caught on CCTV at a Leyland DIY store buying a 3-in-1 saw set, several large plastic buckets and perforated metal sheets.

Brizzi was arrested on April 7 after neighbours complained of the foul stink, and answered the door acting "as cool as a cucumber".

Police arrived at his flat, which had a strong stench of "gone off meat", to find him wearing pink Y-fronts and aviator sunglasses, which a neighbour described as similar to those worn by Tom Cruise in Top Gun.

In the bath tub there were "globules" of flesh floating in acid, while buckets full of human remains lay on the floor. Officers found a hand and a spine in a bin bag.

After his arrest, he asked police if he could take a shower, as his bath had been "unusable for days".

He also told the officers: "I've tried to dissolve the body. I met him on Grindr and I killed him. Satan told me to."

Brizzi moved to London from Italy in 2011, and lost his job at Morgan Stanley in 2014 because of his drug addiction.

PC Semple, who was originally from Inverness in Scotland and lived in Greenhithe, was reported missing by his partner, Gary Meeks, after he failed to return home from work.

A post-mortem examination found he had been strangled and struck in the face while alive, although it later gave the cause of death as "unascertained" because of the dismemberment.

After the sentencing, Commander Nick Downing, from the Met Police, said: "Today, my heart goes out to Gordon's partner, family, loved ones, friends and colleagues. They have my deepest sympathy; his loss continues to be acutely felt.

"Brizzi has shown no remorse for his actions, since the time of his arrest and throughout his trial. With today's sentence a dangerous man, whose cold calculated actions were deeply disturbing, is behind bars."

Mr Semple's family said in a statement: "Gordon continues to be sadly missed by our family. Gordon we miss you so much, may you rest in peace.

"Gordon was a loyal and much loved long term partner, brother, brother-in-law, uncle, cousin and friend to all.

"We were devastated when the news broke of Gordon's murder and the circumstances which are still incredibly hard to deal with. It is still insurmountably upsetting. Nothing takes away the pain of our loss.

"At Gordon's funeral we met many of his friends and work colleagues - we were proud to hear how fondly they thought of Gordon."
