(WLAX/WEUX) – A Minnesota woman is now charged with the death of her newborn who was abandoned at a lake nearly 20 years ago. Authorities say she is the mother of another baby whose body was found in the Mississippi River years earlier.

50-year-old Jennifer Matter, of Red Wing, was charged with second-degree murder in the December 2003 death of a newborn boy whose body was found on the shore of Lake Pepin.

According to court documents, Matter is also the mother of another infant, a girl, found in the Mississippi River in 1999, although charges have not been filed in that case, which is still under review.
