SUNBURY, Pa. -

A Pennsylvania woman charged with her newlywed husband in the murder of a man they met through Craigslist has admitted in a jailhouse interview to the slaying and says she has killed more than 20 others.

The Daily Item in Sunbury, Pa., reported that police are investigating 19-year-old Miranda Barbour's claims of killing at least 22 others from Alaska to North Carolina that she said was part of her involvement in a satanic cult.

Sunbury police Chief Steve Mazzeo tells the newspaper that investigators have been in contact with the FBI and law enforcement in several other states. Lawyers for the couple didn't immediately return messages.

Prosecutors are seeking the death penalty against Barbour and 22-year-old Elytte Barbour in the death of Troy LaFerrara in November.
