A satanic killer and her husband have avoided the death penalty after they pleaded guilty today to fatally stabbing a married man whom she lured to his death using Craigslist.

Miranda Barbour, 19, and her husband, Elytte Barbour, 22, stabbed and strangled Troy LaFerrara in Pennsylvania, after he responded to her ad for 'female companionship' last November.

They appeared for a pre-trial hearing in Sunbury, Pennsylvania on Tuesday morning ahead of what was expected to be a high-profile case involving claims of cult killings and sordid sexual encounters. They will be sentenced on September 18.

Both killers have pleaded guilty to additional charges of aggravated assault, robbery and possessing an instrument of crime, dailyitem.com reported.

Barbour claimed in a jailhouse interview on Valentine's Day this year that she killed at least 22 other people over six years in a cross-country murder spree motivated by her satanic cult beliefs.

She said that although the FBI has not she was prepared to show authorities where she hid the bodies.

'I said before I would talk to them (FBI) about all of this, but they never came to see me,' she told The Daily Item. 'They are looking for full bodies. They won’t find any. But they will find body parts.'

The couple, who were only three weeks married when they murdered, were spared the death penalty today (pictured entering court)

The Daily Item reported that local investigators in three murder locations named by Barbour are taking the claims seriously, but said they have no unresolved homicides they know about.

Barbour said she dumped some body parts in Big Lake, Alaska, and also in Mexico Beach, Florida where she worked as a 15-year-old go-go dancer.

She also said she dumped a body off Interstate 95 near Raleigh, North Carolina.

Barbour lived in Alaska, Florida and North Carolina before moving to Selinsgrove, Pennsylvania last fall with her husband.

Sunbury police said the couple murdered LaFerrara the day of their three-week wedding anniversary and Elytte Babour's 22nd birthday.

Elytte Barbour had allegedly told police he and his wife wanted to kill together.

Barbour claimed she killed 22 people in the past six years in Alaska, Texas, North Carolina and California.

Explaining that she adopted a murderous alter ego she dubbed 'Super Miranda' when she killed, Barbour said that she kept a favorite knife that had notches on - one for each of her victims.

According to the article Barbour based her actions on fictitious TV serial killer Dexter, only killing bad people - those who abused children or owed money and that her satanism controlled her murderous rages.

Amid these gruesome claims, the tiny Alaskan town of North Pole has become the center of the outlandish story about satanism and serial killers that Barbour claims began at the behest of a cult leader. Barbour claimed she joined a cult aged just 13 in the town of North Pole and then spent her teenage years on a nationwide killing spree.

However, she said the 'majority' of slayings took place in her home state.

Investigators are also pouring over the sordid Craigslist encounters that Barbour and her husband Elytte organized for cash in the months prior to her arrest while they lived in Dunn, North Carolina.

Elytte Barbour told The Daily Item of Sunbury that Miranda Barbour, whom he married October 22, regularly hired herself out as a 'companion' from $50 to $850 an hour to men she met on various meet-up websites.

He said he did not mind this because there was no sexual contact between his wife and her clients.

'She is not a prostitute,' he said at the time. 'What she does is meet men who have broken marriages or have no one in their lives, and she meets with them and has delightful conversation.'

However, when Barbour met married Troy LaFerrara through Craigslist, it wasn't for conversation.

Barbour told police in December that LaFerrara was still alive and 'choking and gasping for air' as she and her husband tried to find somewhere to dump his body after stabbing him 20 times.

Initially, Miranda told police that she killed La Ferrara in self-defense after he started to grope her.

But her husband Elytte Barbour gave police a different story, saying they conspired to kill a stranger together, and he helped hold La Ferrara down while his wife wielded the knife.

Miranda Barbour was the first to be arrested when police traced LaFerrara's last call to her cell phone.

Investigators said Elytte Barbour confessed to police the couple planned the killing. He previously told The Daily Item of Sunbury his wife acted in self-defense when LaFerrara, who was married, groped her after hiring her as a ‘companion.’

According to authorities, Miranda advertised herself as a 'companion' on Craigslist and LaFerrara responded.

She arranged to pick him up on November 11 at a mall, three weeks after her marriage.

Elytte Barbour says he hid in the back of the car under a blanket until the moment his wife gave him a signal.

He held LaFerrara back with a cable cord while his petite, bespectacled spouse repeatedly stabbed him. LaFerrara's body was discovered the next morning in an alley by Sunbury resident Brittany Settler.

After dumping their victim's body, the Barbours when to Wal-mart to buy garbage bags, carpet clearer, paper towels and seat covers to clean out the SUV - but it wasn't enough.

'She related that there was a lot of blood and she wasn't able to get it all,' police said.

After that they went to a strip club to celebrate Elytte's 22nd birthday.
