Seventeen years ago, a Waste Management worker was emptying trash cans in Stickney Township, Cook County, when she found a pair of newborn twins. The infants were dead and their umbilical cords were still tied, according to Chicago Tribune compared to the time.
During their investigation at the time, police spoke to neighbors and pregnant women in the area, but were never able to resolve the case.
On Saturday, however, the Cook County Sheriff’s Office announced a breakthrough: They had charged the mother of the infants, Antoinette Briley, with two counts of first degree murder.
In 2003, authorities ruled that the deaths of the newborns were homicide after an autopsy found they were born alive and died of asphyxiation. The case remained cold for over a decade, until police reopened it in 2018.
As they resumed their investigation, detectives used what a press release provided to The Daily Beast described as “the latest developments in genetic genealogy” to try to identify the birth mother of the twins.
Detectives from the Cook County Sheriff’s Office then traveled to Briley’s home state, where they obtained a discarded item containing his DNA. It matched the DNA of the victims.
Finally, on Thursday, police received a clue that Briley was in Cook County. They arrested her after a traffic stop at Oak Lawn on Friday, with a bail hearing scheduled for Saturday afternoon.
