A man who fatally stabbed a real estate agent inside a model home in suburban Dallas faces execution Wednesday evening, more than 16 years after the slaying.
Kosoul Chanthakoummane was on parole when he was condemned for killing 40-year-old Sarah Walker in July 2006. She was found stabbed more than 30 times in the model home in McKinney, about 30 miles (48 km) north of Dallas.
