EAST ST. LOUIS, Ill. (AP) — A man accused of robbing a southwestern Illinois bank is a suspect in at least six other holdups around the country, including one in Lusk, Wyoming.

Carl Frederick Kieffer made an initial court appearance Wednesday in East St. Louis, one day after he was arrested near a Swansea corn field. The 49-year-old from Spokane, Wash. is charged with robbery after authorities say he stole about $3,300 from the Bank of O'Fallon.

Court documents show he's also a suspect in at least six other robberies. They include heists in Lusk, Wyoming, Novi and Charlotte, Michigan; Tipp City and Bolivar, Ohio; and Farmersville, Ill.

Prosecutors say Kieffer's case will first proceed in Illinois. Federal bank robbery charges carry a 10-year prison sentence and a $250,000 fine.

Kieffer's lawyer waived a detention and preliminary hearing.
