A man from the northwest Iowa town of Remsen will remain behind bars for the death of his ten-year-old adopted son. The Iowa Appeals Court today affirmed the first-degree murder conviction of Donald Boss. A Plymouth County jury found Boss guilty in December of 2002 in the murder of Timothy Boss. Testimony indicted the child died after he was tied to a chair and beaten in February of 2000. The appeals court considered claims Donald Boss’ court-appointed attorneys were ineffective and that a jury was prejudiced because a request to move the trial was denied. The appeals court also reviewed a claim the jury verdict wasn’t supported by the weight of the evidence.
