(CNN) First, authorities discovered a spine-chilling 2,246 fetal remains in the Illinois garage of an abortion doctor after his death. Then, investigators found "thousands" of abandoned medical records across his abortion clinics in Indiana, the Indiana attorney general announced on Friday.

Indiana Attorney General Curtis Hill called Dr. Ulrich Klopfer one "of the more notorious abortionists in the history of Indiana."

The doctor had "a record of deplorable conditions and violations of regulatory controls that are placed on these clinics," Hill said. "He certainly was problematic in life and as it turns out continues to present problems in his death."

The remains found in his home date back to abortions he performed between 2000 and 2002, when he operated clinics in Indiana, authorities said. They were inside small, sealed plastic bags that contained a chemical used to preserve biological material, Will County Sheriff Mike Kelley had said.

Klopfer operated three abortion clinics in South Bend, Indiana, before his license was suspended in 2015.
