RED WING, Minn. (AP) — A Minnesota woman has been charged in the death of her newborn who was abandoned at a lake nearly 20 years ago.

Authorities charged Jennifer Matter, 50, of Red Wing, with two counts of second-degree murder in the December 2003 death of a newborn boy whose body was found in Frontenac on the shore of Lake Pepin, a body of water on the Mississippi River.

According to court documents, Matter is also the mother of another infant, a girl, found in the Mississippi River in 1999.

Charges haven’t been filed in that case, which is still under review.
