CLAYTON, Mo. – The St. Louis County prosecutor said he will seek the death penalty again for a man whose sentence in a cold-case murder was overturned last year by the Missouri Supreme Court.

Gregory Bowman was convicted in 2009 of raping, strangling and cutting the throat of 16-year-old Velda Joy Rumfelt in 1977.

In April 2011, the state Supreme Court affirmed Bowman’s conviction in the killing but reversed the death penalty, sending the case back to the trial court for resentencing. The state Supreme Court ruled that during the sentencing phase of Bowman’s trial, jurors improperly heard information about Bowman’s convictions in the deaths of a 14-year-old girl and a 21-year-old woman in Belleville, Ill. Both of those convictions were overturned after a sheriff’s deputy admitted tricking Bowman into confessing.
