One week ago, Jim Stack was declared a hero. Now he's in jail.

Stack, 30, was praised by police last week for disarming a man who went berserk on a Greyhound bus, killing a college student and seriously injuring another passenger.Upon hearing of Stack's heroics, a security agency offered him a job. But a background check turned up a Texas arrest warrant for parole violations stemming from a 1982 rape conviction.

Stack was paroled for the offense, but instead of reporting to a parole officer in Harris County, Texas, he came to Bloomington, where he had gone to high school, authorities said.

From a city jail cell Tuesday, a cheerful Stack said he would do it all over again even if his heroic actions end up costing him his freedom.

Bloomington Police Chief Mike Miller said he would write a letter on Stack's behalf to the Texas parole board asking members to weigh the events of last Tuesday when considering Stack's future.

Peirre Savoie, 26, of the Kankakee, Ill., area was charged with murder and attempted murder in the Greyhound attack and was in custody at the McLean County Jail.
