A Kansas City area prosecutor says he will seek the death penalty for the couple charged with the brutal sexual assault and murder of a Kansas City woman. The saga that led to charges being filed against Richard Davis and Dena Riley in the death of Michelle Ricci began with a horrifying video tape of the sexual assault and murder of Marsha Spicer of Independence. In investigating the death of Spicer, detectives began following leads that led to the discovery of Ricci’s body. Her charred remains were found in a wooded area of Clay County. Dental records had to be used to identify her. Authorities believe Davis and Riley sexually abused and killed Ricci several weeks before the Spicer murder. Clay County Prosecutor Daniel White says he will seek the death penalty, because the most vile criminal act should be subject to the ultimate punishment.
