These are the shocking CCTV pictures that helped bring evil  dad Mick Philpott to justice, the  Sunday People reports.

They show Philpott laughing and crooning Elvis Presley’s hit Suspicious Minds  with the damning line “We’re caught in a trap” – just days after he killed six  of his kids in a house fire.

Pub customers watched in astonishment as the dad of 17 – dressed Blues  Brothers-style in black trilby and sunglasses – picked up a microphone and  belted out the karaoke track at The Navigation Inn in Derby.

His killer wife Mairead, also in a trilby, can be seen giggling as she sits  on his knee before joining him in a duet.

The CCTV footage, obtained exclusively by the Sunday People, provided police  with one of the final pieces of the jigsaw they needed to charge him with the  blaze deaths.

Police collected the film on May 30 last year, less than nine hours before  charging Philpott, 56, and his wife Mairead, 32.

Philpott was jailed last week for life for manslaughter while Mairead got 17  years along with pal Paul Mosley, 46.

The couple had played the part of devastated victims, wiping away crocodile  tears and feigning grief in front of the media just days after a blaze ripped  through the family semi in Derby on May 11.

Philpott claimed the fire had been instigated by an arsonist.

But on the evening of May 26 – just 15 days after the devastating house fire  he had started deliberately with petrol – Philpott let his facade slip.

The pair sauntered into the pub at around 4.30pm, happily downing vodka shots  and Jack Daniels and Coke before getting on the karaoke to sing the 1975 Elvis  classic.

The pair were unaware the pub’s CCTV cameras were picking up the entire  brazen performance – turning the police’s murder investigations firmly on  them.

The song Suspicious Minds is about a couple’s mistrusting and dysfunctional  relationship, and the need to overcome their problems.

Philpott sang the lyrics: “We’re caught in a trap, I can’t walk out, because  I love you too much baby.”

Navigation Inn landlady Jeanette Doherty told the Sunday People: “The two of  them were up dancing and having a good time.

“She was round the pool table grinding up against young lads.

“She was drinking Bacardi and JD as well as Malibu and Coke. He was drinking  JD and vodka.

“It was bizarre behaviour. It’s hard to imagine what you would do, but it  wouldn’t be going out drinking and doing karaoke.

“We had a party in celebrating a First Holy Communion. There were a lot of  kids there.

“At first people were just shocked that Mick and Mairead were even there. You  don’t expect to see a couple whose six children have just died to be out  partying.

“They were laughing and joking – it was just unbelievable. I don’t know how  they could live day to day knowing they had caused their six kids to die, let  alone go out enjoying themselves.”

Landlord Russell Doherty said: “I came in just after he had left.

“Everyone was saying to me ‘Guess who was just in here!’

“He was the most infamous man in Derby at the time. He was well-known even  before the fire.

“There was a guy up singing Suspicious Minds and then Mick Philpott picked up  the mike.

“He also sang My Boy by Elvis. People just couldn’t believe it. It was the  talk of the pub for days afterwards.

“It made people think something strange was going on and there was something  not quite right.”

Philpott’s former pal Michael Garland, who was in the pub on the night, said: “I’ve turned to the lad that’s singing and asked him to stop because of the kids  being caught in that fire in the trap.

“And as I’ve turned to say that, Mick has come running past me and grabbed a  microphone and started singing ‘I’m caught in a trap!’

“When he’d finished I said ‘Mick you better go because people aren’t happy  with you’.”

After their callous show they went to the beer garden but their appalling  behaviour led to them being forced to leave the pub shortly before 8pm that  night.

Fellow drinkers were so suspicious they contacted the police.
