Appeals that seek to spare the life of a Missouri man facing execution this week focus on concerns about the lethal injection drug.
William Rousan is scheduled to die at 12:01 a.m. Wednesday. He was sentenced to death for killing 62-year-old Grace Lewis in 1993. He was sentenced to life in prison for killing her 67-year-old husband.
The killings were part of a plot by Rousan, his son and his brother, to steal cattle from the Lewis farm near Bonne Terre.
Rousan's son, Brent, was 16 at the time of the killings. He is serving life without parole. Rousan's brother, Robert, pleaded guilty to second-degree murder and served seven years in prison.
An appeal in federal court questions Missouri's secretive process of purchasing execution drugs from an unnamed compounding pharmacy.
