LAGRANGE PARK, Ill. (CBS) -A fetus was found on Saturday in the hallway of a west suburban church, according to the Cook County Medical Examiner’s office.

The fetus was reportedly found as 5:30 p.m. Mass was taking place at St. Louise de Marillac Catholic Parish in La Grange Park.

Father Denis Condon said the mother, a parishioner who regularly attends Mass at St. Louise, had a miscarriage in the women’s bathroom during Mass Saturday evening.

The mother fled, likely because she was “traumatized” Condon said, but was found later Saturday night and taken to a nearby hospital. She was expected to be released today, he said.

Another worshipper found the fetus in the hallway outside the bathroom and an usher alerted Condon, who dialed 911.

The congregation prayed for the mother’s safety at Mass this morning and last night, he said.

“I told the people about the tragedy and we prayed for the mother, that she’d get medical attention and recover,” he said.

The fetus was transported to the Cook County Medical Examiner’s office, according to a release from the LaGrange Park Police Department. An examination Sunday determined the fetus was non-viable, and there was no death certificate issued.

The investigation remains open. Anyone with information about the incident is asked to call (708) 352-2151.
