SUNBURY, Pa. — The father of a Pennsylvania woman who with her newlywed husband is charged with killing a man she met through Craigslist said he would support his daughter’s execution if she is found guilty.

Sonny Dean said Wednesday that he believes his 19-year-old daughter, Miranda Barbour, may have been involved in one other murder besides the Nov. 11 fatal stabbing of Troy LaFerrara, 42, in Sunbury.

Police said LaFerrara met the young woman through her Craigslist ad, which offered companionship in exchange for money.

Investigators allege Miranda Barbour stabbed LaFerrara of Port Trevorton about 20 times in her parked car as her husband, Elytte Barbour, held a cord tight against LaFerrara’s neck from the back seat and then dumped his body in an alley.

Dean told the newspaper that his daughter was a heroin addict and is a liar and manipulator, but he doesn’t think she is a mass murderer. “Miranda lives in a fantasy world,” he said.

Last Friday, Miranda Barbour told a news outlet in Sunbury she killed fewer than 100 people but stopped counting at 22. She said she lured a man into an alley in Alaska and watched as the leader of a satanic cult to which she belonged shot the man before telling Barbour it was her turn.

“Believe very little of what Miranda says,” said Dean, of Texas. “She has a long history of extreme manipulation and dishonesty.”
