This Michigan mother was charged yesterday with two counts of first degree murder for the deaths of her newborn twin sons in Stickney Township, Illinois, 17 years ago. A Waste Management employee who was emptying trash bins in an alley discovered the newborns who were determined to have been born alive and then asphyxiated. An investigation ensued but there was no arrest.

Cook County, Illinois sheriff’s police reopened the case in 2018 and used DNA from evidence recovered at the scene in 2003 in an effort to identify the birth mother using the latest developments in genetic genealogy. The DNA research and subsequent investigations allowed detectives to identify the Michigan woman as the victims’ potential birth mother. Police then traveled to Holland, Michigan to obtain a discarded item containing the woman’s DNA. It matched the DNA from the babies. Police obtained information that the woman was in Cook County and took her into custody after a traffic stop in Oak Lawn, Illinois.

The lead detective Ginny Georgantas said “I’m happy that there’s closure for the twins, there was no one fighting for them.”
