A southwest Missouri man is going to prison for slightly more than eight years for robbing a half-dozen banks in three states, including Iowa and Oregon.

The U.S. Attorney’s office says 49-year-old Kenneth Dewain Parker, of Rockaway Beach, must also pay about $22,000 in restitution under the sentence he received Monday.

Parker pleaded guilty to the holdups last year. The out-of-state cases had been transferred to Missouri.

Parker’s robberies began July 30, 2010, in Eugene, Ore., and ended about six weeks later with a holdup at a bank in Sedalia, Mo.

In between, he robbed banks in Salem and Portland, Ore.; Cedar Rapids, Iowa; and Columbia, Mo.

The amount stolen in Iowa was not disclosed. Prosecutors said the other holdups netted amounts ranging from about $2,200 to $9,100.
