INDIANAPOLIS (AP) — Authorities in a northeastern Illinois county say they won’t be discussing the discovery of more than 2,200 medically preserved fetal remains at the home of a former Indiana abortion doctor until their investigation is completed.

The Will County Sheriff’s Office’s spokeswoman, Kathy Hoffmeyer, said Monday the probe of the late Dr. Ulrich Klopfer’s home is “a very sensitive situation” involving the sheriff’s office, coroner’s office and prosecutors.

Hoffmeyer says no further information will be released until those agencies complete their investigation.

Police said Friday 2,246 preserved fetal remains were found in Klopfer’s Will County home.

Klopfer, who died Sept. 3, was a longtime doctor who performed abortions at northern Indiana clinics.

Four Indiana lawmakers are seeking a state investigation to determine if the remains found at Klopfer’s home were illegally transported across state lines.
