ROCHESTER - A Red Wing woman accused of killing two of her own infants more than two decades ago pleaded guilty Wednesday in the murder case of one of the babies, who was found on the banks of the Mississippi River in 2003.
Jennifer Lynn Matter, 50, entered a guilty plea in Goodhue County District Court for second-degree intentional murder as part of a plea agreement with prosecutors that could result in a prison sentence of up to 27 years. Another second-degree murder charge in the case has been dropped.
District Judge Douglas Bayley will announce the sentence at a hearing on April 28.
Goodhue County investigators announced last May they had arrested Matter at her home outside Red Wing as part of a cold case investigation into the deaths of two infants found in or near the Mississippi River in 1999 and 2003. The cases helped inspire Minnesota's "safe haven" law granting immunity to mothers who safely give up their newborns up to 7 days old.
According to court records, DNA testing determined Matter was the mother of both infants, though she was only charged in the December 2003 death. Four teenage girls stumbled across the unclothed infant's body lying on Methodist Beach in Florence Township, his umbilical cord still attached and wrapped around the middle of his body.
The Minnesota Regional Coroner's Office conducted an autopsy of the infant and determined the boy was likely born alive. Coroners found the infant died as a result of homicide, but the specific cause of death is unknown. The baby had blunt force head injuries, possibly from the birth process.
DNA tests done in 2004 and 2007 concluded the two infants were related. Investigators in 2021 used genetic testing to identify the biological father of the infant, which led police to consider Matter a person of interest.
Court records show Matter at first denied being the mother of either infant and refused to submit a DNA sample. But investigators obtained a search warrant and got Matter's DNA, which showed she was likely the mother of both.
