CHICAGO (WBBM NEWSRADIO) -- Cook County sheriff’s police announced Saturday that they have charged a Michigan woman with murdering her newborn twin sons 17 years ago.

Antoinette Briley, 41, of Holland, Mich., was charged Friday night with two counts of first-degree murder for the deaths of her sons, according to a Cook County sheriff’s office press release.

On June 3, 2003, a Waste Management employee discovered the bodies of the infants while emptying trash bins in an alley just outside of Chicago in unincorporated Stickney Township.

A subsequent autopsy determined the babies were born alive and died of asphyxiation, and the deaths were ruled homicides, the press release continued.

Despite conducting an investigation at the time, the case remained unsolved.

Sheriff’s police reopened the case in 2018 and used DNA from evidence recovered from the scene in an effort to identify the birth mother with the latest in genetic genealogy development. A breakthrough from that research and subsequent investigations allowed detectives to eventually identify Briley as the twins’ potential birth mother.

Sheriff’s police detectives had travelled to Holland, Mich. and obtained a discarded item containing Briley’s DNA, which was matched to the DNA from the victims. On Thursday, Sheriff’s police learned Briley was in Cook County and took her into custody after a traffic stop in Oak Lawn.

Briley is scheduled to appear at 12:30 p.m. Saturday  for a bond hearing on the charges.
