A slain southern Indiana woman's father wants a death sentence for the man who admitted killing her and burying her body. Four days of testimony ended Thursday on whether a judge should give William Clyde Gibson III the death penalty for the strangulation death of 35-year-old Stephanie Kirk of Charlestown. Her remains were found buried behind his New Albany home in 2012. Gibson's already been given the death penalty for killing a 75-year-old family friend and a 65-year sentence for the stabbing death of a 44-year-old woman. Tony Kirk told reporters he believed Gibson should die for killing his daughter. Defense attorney Patrick Biggs argued a second death sentence for Gibson is unnecessary and cited his history of alcoholism and bipolar disorder. The judge set Gibson's sentencing for Aug. 15th.
