KANSAS CITY, Mo. (AP) — Federal prosecutors plan to dismiss charges against a man who allegedly made a threat at Kansas City International Airport on the 2011 anniversary of the 9/11 attacks.

The Kansas City Star reported Thursday prosecutors say in court records that Anthony Falco Jr. suffers from schizophrenia and is not likely to become competent to stand trial.

Federal prison authorities have twice determined Falco is not a danger to society, which prevents him from being committed to a mental institution without his consent.

Prosecutors say that forces them to ask a judge to dismiss the indictment.

Falco, whose last known address was East Petersburg, Pennsylvania, was taken into custody since Sept. 11, 2011, when he was accused of trying to carry bags filled with fake bombs through an airport checkpoint.
