Louisiana parolee set to be executed tonight in Huntsville

Man killed his girlfriend in East Texas

Headline Goes Here

HUNTSVILLE, Texas -  A man on death row for the murder of a Polk County dental assistant will be put to death tonight in Huntsville.

When Louisiana parole violator Donnie Lee Roberts was arrested for fatally shooting his girlfriend at her East Texas home nine years ago, the first thing he told police who questioned him was that he wanted the death penalty.

The 41-year-old Roberts faces lethal injection in Huntsville for the slaying of 44-year-old Vicki Bowen.

A co-worker who became concerned after the dental assistant failed to show up for work discovered her body at Bowen's home near Lake Livingston in Polk County. Roberts also confessed to another unsolved homicide in Louisiana committed 12 years earlier.

Evidence showed Roberts fled a Louisiana drug treatment program. He'd already been convicted of a robbery in Baton Rouge.

The U.S. Supreme Court on Monday refused to review his case.
