A Pennsylvania woman jointly charged with murder with her husband has claimed she has killed at least 22 other people.
Miranda Barbour made the confession in an interview with The Daily Item claiming her murder spree was part of an involvement in a satanic cult.
The 19-year-old said she was just 13 when she began the nationwide killing spree in her home state of Alaska, adding: "When I hit 22, I stopped counting."

“I can pinpoint on a map where you can find them,” she told the newspaper, adding that most of the people she murdered were in Alaska.
Miranda and Elytte Barbour are currently charged with killing Troy LaFerrara after meeting him online after placing an ad in classifieds website Craigslist, offering companionship for money.
Police claim Mr Barbour told investigators they committed the crime simply because they wanted to kill someone together.
The FBI said Sunday they were in contact with local police in several other states in response to the new claims there could be further victims.
"The FBI's Philadelphia Division has recently been in contact with the Sunbury Police Department regarding Miranda Barbour, and will offer any assistance requested in the case," FBI spokeswoman Carrie Adamowski told NBC News on Friday.
Barbour told The Daily Item she started murdering people when she was 16, shortly after she joined a satanic cult in Alaska.
She said she had no remorse and only killed "bad people."
Barbour said she wanted to admit to the killings because "if I were to be released, I would do this again."
Prosecutors are seeking the death penalty against Barbour and her newly-wed husband. The couple originally pled not guilty to the slaying in which Elytte strangled LaFerrara from behind while Miranda stabbed him over 20 times.Suggest a correction
