(CNN) A month after 2,246 fetal remains were found in the Illinois garage of a doctor who performed abortions, more remains linked to him have been found.

Dr. Ulrich Klopfer died on September 3. His family found medically preserved remains while going through his belongings at his home in Will County, about 45 miles from Chicago, authorities said last month.

The discovery of additional fetal remains was announced Wednesday during a news conference held by the Indiana Attorney General. Klopfer operated in three abortion clinics in Indiana.

"Today we were notified by authorities in Illinois that family members this morning found additional fetal remains as they continued to sort through the late doctor's belongings," Attorney General Curtis Hill said.

"Dr. Klopfer apparently had a series of vehicles, my understanding is approximately eight vehicles on the property. When looking at the vehicles there did not appear to be anything unusual inside the vehicles, but they did discover, in one vehicle's truck, items that contained the remains of aborted fetuses, were in that trunk," Hill said.
