DAYTON, OH — An Ohio woman convicted of killing her month-old baby daughter in a microwave oven was spared the death penalty and sentenced last Friday to life in prison without parole.

Montgomery County Common Pleas Judge Mary Wiseman sentenced China Arnold, 31, of Dayton, who psychologists testified showed no signs of serious mental illness. Arnold declined to make a statement during her sentencing.

Arnold was convicted last week of aggravated murder by the same jury that recommended her punishment. Jurors deliberated about six hours Thursday and Friday.

Prosecutors say Arnold intentionally put 28-day-old Paris Talley in a microwave and turned it on after a fight with her boyfriend. The couple had argued over whether the boyfriend was the infant’s biological father.
