Investigators used new advances in genetic genealogy to charge a Michigan woman with murder in the 2003 deaths of her twin newborn sons, said Sheriff Thomas Dart of Cook County, Illinois, on Saturday.
Antoinette Briley, 41, of Holland, Michigan, is charged with two counts of first-degree murder.
Briley was arrested Thursday in Oak Lawn, Illinois, Dart said.
The case began on June 6, 2003, when a Waste Management employee emptying trash bins in an alley in Stickney Township, Illinois, saw the bodies of the boys in the front lift bucket of her garbage truck.
An autopsy determined the children were born alive and died of asphyxiation, Dart said in a press release. The deaths were ruled homicides.
Despite an extensive investigation at the time, the case remained unsolved.
Investigators reopened the case in 2018, utilizing DNA recovered at the scene and the latest developments in genetic genealogy. The effort led to a breakthrough that allowed investigators to identify Briley as the victims’ potential birth mother, the sheriff’s office said.
Detectives traveled to Holland, Michigan, and obtained a discarded item with Briley’s DNA on it, which was matched to DNA from the boys, Dart said.
Investigators learned Thursday that Briley was in Cook County and conducted a traffic stop to take her into custody.
A bond hearing for Briley was scheduled for Saturday afternoon.
