A 19-year-old Pennsylvania woman charged with killing a man she and her husband met on Craigslist had another confession: She has killed people in five states, including Texas.

In a recorded jailhouse interview, Miranda Barbour told The Daily Item that she will plead guilty to murder charges in the death of 42-year-old Troy LaFerrara, and she claimed responsibility for more than 20 other killings across the United States.

"I can pinpoint on a map where you can find them," Barbour said in the interview.

According to The Daily Item, Barbour offered few details of the other killings, saying that she stopped counting her victims when she got to No. 22.

Barbour traced her deadly conduct back to age 13, when she says she joined a satanic cult in Alaska. She told The Daily Item that she'd also killed people in Texas, California and North Carolina.

Although Barbour admits she killed LaFerrara after arranging to meet on Craigslist, it's not known if her other alleged crimes included solicitation on the website. Unrelated to Barbour, Craigslist has been implicated in several Texas killings.

Dallas police believed that Christopher Howard Beachum, 27, arranged a date with Gerald Canepa, 68, through Craigslist on March 15, 2013. Three days later, Canepa was found strangled to death in his South Oak Cliff home. According to the arrest warrant affidavit, Beachum was the last person to communicate with Canepa in person and by phone. Beachum was arrested a few weeks later in Oregon.

In San Antonio, Ezekiel Gilbert used Craiglist to book a date with an escort on Christmas Eve 2009. When Lenora Ivie Frago refused to have sex with him after he'd paid her $150, Gilbert shot her in the neck and paralyzed her. She later died from her injuries.

During his murder trial, Gilbert said he was simply exercising his legal right in Texas "to use deadly force to recover stolen property during a nighttime theft." The jury agreed with his defense and acquitted him of murder on June 5, 2013.
