SUNBURY — During a prison interview, Miranda Barbour said she murdered at least 22 people from Alaska to Texas and that she would be able to “pinpoint on a map” where the killings took place.

And that has authorities concerned.

“We are taking her claims very seriously,” Sunbury Police Chief Steve Mazzeo said. “We have made contact with the FBI, and we have agreed to work with them.”

Mazzeo said federal investigators are en route to Sunbury and should be in the city as early as today.

“I will not discuss any details of any investigations, but we have agreed to liaison with federal investigators on these claims,” Mazzeo said. “We have also been in contact with other authorities in other parts of the country.”

Barbour claimed that, while in Alaska, she had been involved in killings in Palmer, Anchorage, Nome, Wasilla and Big Lake.

Its all part of the Matanuska-Susitna Valley, a huge geographic area that is described as a semi rural.

The former Palmer teenager said she got her start in a satanic cult in Alaska.

In the past five or six years, there are have been at least six missing people or unsolved murders, authorities said.

Less than two weeks ago, Alaska state troopers discovered the body of a Sutton woman who had been missing since 2010, according Anchorage Daily News. Authorities have not yet said what happened.

Barbour, 19, who lived in North Pole and the Mat-Su, left the state in 2011, according to Alaska records.

Palmer has a population of about 6,500, Anchorage, 151,654, Wasilla, 8,456, and Nome has nearly 4,000.

Barbour said the majority of the killings took place in those parts of Alaska.

Barbour also claimed that she had killed in Texas, California and North Carolina.

Alaska law enforcement sources haven’t said whether they’ve launched investigations into Barbour’s claims.

Public records show Barbour filed for Alaska Permanent Fund dividends for years from North Pole and Anchorage addresses, the Anchorage Daily News reported.

Barbour claimed she joined a satanic cult in Alaska when she was 13 and spent her teenage years killing as part of the cult.

She moved to North Carolina from Alaska in 2011, when she was pregnant with her daughter. In North Carolina, she met Elytte Barbour, 22, and they married in October 2013.

Police say the couple used a Craigslist ad promising “companionship” to lure Troy LaFerrara, 42, of Port Trevorton, to his death.

Miranda Barbour stabbed LaFerrara in the front seat of her car while her husband held a cord around his neck, Miranda Barbour said.

Northumberland County District Attorney Tony Rosini is seeking the death penalty against Barbour and her husband.
