Miranda Barbour, the 19-year-old "Craigslist killer", who has admitted murdering a man she and her husband met through the classified advertising website, has claimed in a jail interview that she killed at least 22 more.

Prosecutors are demanding the death penalty for Barbour if she is convicted of murdering Troy LaFerrara, who was lured to his death in the small city of Sunbury, 150 miles northwest of Philadelphia. She and her husband of three weeks Elytte, 22, had placed an ad on the site offering "companionship" in return for money.

LaFerrara got into the car driven by Miranda not realising her husband was hiding in the back seat beneath a blanket. On a pre-arranged signal from his wife he pounced and wrapped a cord round the victim's neck as his wife - then aged just 18 - repeatedly stabbed him.

It is thought LaFerrera was alive for around 20 minutes "choking and gasping for air" as the couple drove round in search of somewhere to dispose of him. They then drove to a strip club to celebrate Elytte's birthday. LaFerrera's body was found in an alleyway; he had been stabbed 20 times. The Barbours have both admitted his killing.

Now the petite, bespectacled mother of one has claimed to have killed at least 22 more victims across the United States, mostly in Alaska, as part of her involvement in a satanic cult.

In a phone interview from Northumberland County Prison, Miranda told local newspaper the Daily Item that she had been abused as a child and grew up in a cult, being introduced to murder at the age of 13 by the leader of the cult, who was owed money by an unnamed man:

"It was in an alley and he shot him. Then he said to me that it was my turn to shoot him. I hate guns. I don't use guns. I couldn't do it, so he came behind me and he took his hands and put them on top of mine and we pulled the trigger. And then from there I just continued to kill."

Sunbury police have confirmed they had been working with the FBI to see if Barbour was involved in other killings even before she made her "confession". Police chief Steve Mazzeo said her claims were being taken very seriously.
