A Charlotte County woman has pleaded guilty to criminal negligence causing the death of her newborn son.

Sarah Marie Russell entered the plea on Monday morning in provincial court in St. Stephen, N.B.

Russell was facing charges of manslaughter, being an accessory after the fact to murder and concealing the body of an infant. Those charges against her have now been withdrawn.

The matter will be back before the courts on Friday when the judge will hear a recitation of the facts and a pre-sentence report will be requested by the defence.

The maximum penalty for criminal negligence causing death is life imprisonment.

Russell was released from custody on strict conditions on March 27.

Rodney Stuart Miller, her common-law husband, was sentenced in October to life in prison after pleading guilty to first-degree murder.

Police found an infant's body in the woods near the home the couple shared in Moores Mills on Jan. 29.
