Winnebago County Coroner Sue Fiduccia says Katie Stockton is in fact their mother. During a news conference this afternoon, Fiduccia identified them as both full-term female infants who are not twins. Their remains were discovered in the trunk of Stockton's car last August, while it was parked in an impound lot in South Beloit. Stockton hasn't officially been charged with their deaths. But is facing murder charges related to her first child "Baby Crystal," who was discovered by the side of the road in Rockton in December 2004. Authorities say they know who fathered one of the babies and need our help in finding the other dad.

"It's important for us to seek information from anybody that would have had an encounter with or an opportunity to be with or relationship with Katie Stockton between December 2004 through mid-2007," says Winnebago County Sheriff Dick Meyers.

Meyers wouldn't elaborate more on why that specific time frame. The infants' cause of deaths are unknown at this time. Fiduccia says further forensic testing is being done to determine whether the babies were stillborn or if they were murdered. Stockton will be back in court February tenth for a status hearing.
