CINCINNATI -- Federal authorities arrested a Maysville, Ky. woman accused of advocating online for terrorist attacks in the U.S. and promoting ISIS propaganda, ABC News reported. Her neighbors can't believe it.
FBI agents arrested Marie Castelli, 55, Thursday, just days before the 15th anniversary of the 9/11 attacks.
An indictment states Castelli posted messages in October 2015 with the names and addresses of three people and wrote that others should "execute" one of them, ABC reported.
"This is not the person I know," said Herbert Freeman, who lives near Castelli. “The Marie that I know doesn’t have an acrimonious bone in her body."
Boone County Jail records indicated Castelli was released to U.S. Marshals Friday. Information about what charges Castelli faces wasn't immediately available.
A woman going by the name "Jihad Marie Antoinette Castelli" wrote in an online forum that she is is a Muslim "without a country that accept me for who I am," and she'd "love to meet face to face Sheikh Osama" and meet his family, ABC reported.

Neighbors said Marie was born in the U.S. but spent time in Egypt while experiencing a difficult divorce. She has lived in Maysville for around five years, according to Freeman.
A source told ABC that the upcoming 9/11 anniversary was "not implicated in any way" as a reason for moving forward with the case.
Freeman expressed disbelief that his neighbor could have deserved a federal arrest.
"In this point and time in America when you wear Arabic attire, it’s hard to get a fair shake," he said.
