Arizona prison inmate, wife indicted on terrorism charges

An Arizona prison inmate and his wife have been indicted on state terrorism charges.

The Arizona Attorney General's Office say Thomas Orville Bastian and Michelle Marie Bastian are accused of plotting to commit an act of terrorism at the state's prison complex in Buckeye.

The couple allegedly conspired to construct and set off an explosive device within the prison facility.

Thomas Bastian is accused of four felony counts including terrorism, conspiracy to commit terrorism, conspiracy to commit terrorism involving weapons and conspiracy to promote prison contraband.

Prosecutors say Michelle Bastian is facing the same counts as her husband plus one felony count of promoting prison contraband.

She allegedly sent articles from al-Qaida and Islamic State magazines that were found in Thomas Bastian's cell. He's serving a life sentence for murder.

"Homegrown terror attacks are being planned in our communities, our cities, and our state," stated Attorney General Mark Brnovich. "The Arizona Attorney General's Office and the FBI will continue to work together to arrest and prosecute anyone plotting or planning a terrorist attack."

"Terrorism remains the FBI's top priority and we work closely with our federal, state, and local partners to ensure the safety of our community," said Michael DeLeon, Special Agent in Charge of the FBI Phoenix Field Office. "This investigation demonstrates the inherent danger of terrorist propaganda, and also highlights law enforcement's commitment to combat terrorism."
