“The officers needed to force entry into that bathroom where they located the mother submerged in a tub of water, suffering from what appeared to be self-inflicted stab wounds to her neck and chest area. The officers then disarmed her, as she was still in possession of the knife,” Plymouth Police Chief Mike Botieri told reporters.

Rezac was taken to a hospital in Boston.  She is charged with armed assault with intent to murder, aggravated assault and battery with a dangerous weapon, and reckless endangerment of a child.
