Charter bus driver had 3 previous DUI arrests

BOZEMAN (AP) — A charter bus driver arrested for drunken driving in Yellowstone National Park while hauling a bus load of middle school students on a field trip had been arrested three times before for driving under the influence.

The Bozeman Daily Chronicle reports a search of public records found Jack Kane Parrent Jr. was convicted of drunken driving in Columbia Falls in 1991 and Lewis and Clark County in 2001.

The Chronicle also found Parrent was charged with drunken driving in Vancouver, Wash., in 1998. A Clark County, Wash., clerk says Parrent has a warrant out for his arrest on that charge.

Karst Stage owner Jerry Perkins says the previous DUIs did not show up in the background checks run by the bus company's insurance provider.
