(CBS/AP) - Jurors found a Dayton, Ohio woman guilty Friday of burning her 28-day old daughter to death in a microwave.
China Arnold, 31, was convicted of aggravated murder in the August 2005 death of Paris Talley, a verdict that could carry the death penalty.
Prosecutors say Arnold put the child in the microwave after a fight with her boyfriend. According to medical experts testifying at the trial, the infant was likely in the device for more than two minutes before she died.
Assistant Prosecutor Dan Brandt told jurors in court that Arnold's actions were "even more purposeful" than a slaying with a gun or knife, the Dayton Daily News reported.
This is Arnold's third time on trial for the murder. The Ohio woman's first trial ended in a mistrial and her conviction in the second trial was overturned by an appeals court, which found misconduct by prosecutors, and said the trial court made an error by not allowing a material witness to testify in Arnold's defense.
The sentencing phase of Arnold's latest trial was scheduled to begin Monday, but will be delayed three days for a mental exam of the defendant, reports the Dayton Daily News.
