A federal appeals court has upheld the death sentence of a man convicted in the slayings of three family members in Pope County. Danny Lee was convicted of the deaths in what federal prosecutors said was part of a white supremacist plot to overthrow the government. Also convicted was Chevie Kehoe, who drew a sentence of life in prison. The Eighth U-S Circuit Court of Appeals in St. Louis ruled today that the death penalty was not arbitrarily imposed in Lee`s case. The appeals court also ruled that the federal death penalty is constitutional. Lee was convicted in May 1999 in the deaths of Tilly gun dealer William Mueller, his wife Nancy and her eight-year-old daughter Sarah Powell in January 1996. Their bodies were found in a backwater of Illinois Bayou north of Russellville. A jury recommended the sentences for Lee and Kehoe.
