BOLIVAR, Mo. (AP) – A Bolivar woman accused of causing the death of her 15 year-old son is no longer facing a murder charge.

A Polk County authorities dropped a second-degree murder charge against 41-year-old Danielle Baker, a registered nurse who was accused of supplying liquid morphine and other controlled substances to her 15 year-old son. He died of an overdose March 20 at the family’s home.

The morphine was traced to a patient who died at Citizens Memorial Healthcare Facility where Baker worked.

The charge was dropped under a law that allows someone to call for medical help for a person who is overdosing without fear of facing charges. Baker called 911 to report her son’s emergency.

Baker is still charged with stealing a controlled substance, tampering with physical evidence and endangerment of a child.
