A Des Moines developer has started a 30-day stint in Marion County Jail after turning himself in for contempt of court. 52-year-old John Kline was ordered to sign a confession of judgment of almost 43,000 dollars to his ex-wife Phyllis earlier this year, as well as pay back thousands of dollars on property debt. Marion County Sheriff Ron Goemaat said that instead, Kline turned himself in early Monday to begin a 30-day sentence to purge the charge. Kline is also facing federal charges where he allegedly used construction loans for personal purposes. He and his wife are also facing a civil arson trial after their home burned down in 2009.
