PHOENIX (AP) -- Prosecutors are seeking the death penalty against a man accused of killing his cellmate in a Maricopa County jail while he was incarcerated on another murder charge.
The Maricopa County Attorney's Office says Andrew Ward, 27, should face the death penalty in the April 2 death of cellmate Douglas Walker, 33, because Ward carried out the killing with gratuitous violence and in an especially cruel manner.
Investigators say Ward stabbed Walker, beat him and forced a plastic bag down Walker's throat.
Prosecutors are also seeking the death penalty against Ward in the March 12 fatal stabbing of his 12-year-old half-brother.
Investigators say Ward explained his motive in his half-brother's death by saying, "Honestly, I just felt like killing."
Ward has pleaded not guilty to charges in both cases.
