Miranda Barbour, known as the notorious Craigslist Killer, has said she had no regrets about the murder of 22 people she claims to have killed.

Barbour told Newsweek magazine that she felt no regret over the murder of Troy LaFerrara, which led to her arrest in December 2013.

She said: "I felt no regret. None. I didn't hurt anyone who didn't deserve it."

Barbour is charged with criminal homicide for the murder of LaFerrara last November. Along with her husband Elytte, she lured LaFerrara with the promise of "companionship" in exchange for $100 on the classified advertisements website Craigslist.

She said this was why she felt LaFerrara deserved to die. The 42-year-old electrical engineer from Sunbury, Pennsylvania, had answered to an advert which promised relations in exchange for money.

"People think I'm a monster, but I've done a lot of good," she said. "The justice system doesn't work, so I did what I did." Barbour added that she had spared "hundreds" of young girls from abuse.

In November, Barbour waited for LaFerrara in the car park of the Susquehanna Valley Mall. Hiding under a blanket on the back seat of the car was Elytte, Barbour's husband of three weeks.

The plan was for Elytte to ambush LaFerrara with a cord and strangle him, in response to the code words "Did you see the stars tonight?". 

Yet Barbour said that it did not go as planned. Wanting to save LaFerrara, Barbour told him she had lied about her age and that she was only 16. She said that this had not put him off and he continued to place his hand on her thigh. According to Barbour, when Elytte failed to pounce after she uttered the code words, she stabbed LaFerrara 20 times.

While Barbour expressed no regret over his murder, she said she felt guilty for the pain she had inflicted on her family with her killer reputation. "I knew I would be put away, but I just didn't think it would all happen so quickly," she said. "I thought I would have more time to say good-bye."

Last week, Barbour's attorney filed a motion asking a judge to rule that she did not torture LaFerrara before killing him, to reduce the possibility of facing the death penalty.

Barbour is due back in court on 30 May.
