Police say mother microwaved her baby

A mother was arrested on suspicion of murdering her newborn daughter by microwaving the baby in an oven.

China Arnold, 26, was jailed Monday on a charge of aggravated murder, more than a year after she brought her dead month-old baby to a hospital. Bail was set Tuesday at $1 million.

"We have reason to believe, and we have some forensic evidence that is consistent with our belief, that a microwave oven was used in this death," said Ken Betz, director of the Montgomery County coroner's office.

He said the evidence included high-heat internal injuries and the absence of external burn marks on the baby, Paris Talley.
