CHEYENNE, Wyo. — A 25-year-old Wyoming mother accused of killing her 16-month-old baby has pleaded not guilty to the charges against her.

KGAB-AM reports (http://bit.ly/2wPDenm ) Sabrina A. Sawicki appeared in court on Monday, denying charges of first-degree murder and aggravated child abuse.

An autopsy determined the boy died from “abusive head trauma” consistent with “shaken baby syndrome.”

Sawicki remains free on a $50,000 bond. Her trial is scheduled for November 7.

Court records say the baby was taken to Cheyenne Regional Medical Center on April 24 and then flown to Children’s Hospital Colorado where he was taken off life support on April 27.
