CARTERVILLE, Ill. (KFVS) - A Harrisburg man and woman are dead in an apparent murder-suicide in Carterville.

Police were called to the scene of a shooting shortly before 9 a.m. on Friday, January 6 to a shooting on Plaza Drive, which is parallel with Route 13 and an access road to John A. Logan College.

According to Williamson County Sheriff Jeff Diederich, 32-year-old Michelle Aumiller was shot multiple times outside of Integrated Health Carterville, approximately 10-feet from the door.

Sheriff Diederich said it wasn’t clear if she was an employee or if she was going into or heading out of the building.

Michelle Aumiller was rushed to a Carbondale hospital where she passed away.

Diederich believes the shooting was the result of a domestic-type situation with her estranged husband, 36-year-old Robert Aumiller.

Someone familiar with the family confirmed that Michelle Aumiller was an employee at Integrated Health.

A search quickly began for Robert Aumiller.

As officers searched for him, JALC and and Carterville schools were placed on a precautionary lockdown.

The lockdown was later lifted after the suspect was located.

Sheriff Diederich said Robert Aumiller was found dead with a self-inflicted gunshot wound in a wooded area near the intersection of Cardinal and Cypress Roads in rural Cambria.

Sheriff Diederich said schools throughout Williamson County and Johnson County were on lockdown as an abundance of caution.

“We became aware that there are children involved that were not at the scene, but that were actually attending school” explained Diederich. “And so we wanted to make sure that the safety of those children as well as all of our children, and all of our communities were safe.”

South of the situation in Johnson County, Vienna High School Superintendent Joshua Stafford released a statement saying the Johnson County Sheriff’s Office requested the high school and all schools in the county to go on a precautionary lockdown because of the shooting. This lockdown has also been lifted.

The couple had family connections at the school, according to District officials.

Integrated Health also addressed what happened on their Facebook page, announcing they would be closed for the rest of the day and Saturday. They also thanked the public for their texts, calls and prayers.

In addition to the Williamson County Sheriff’s Office and Carterville Police, members of the Herrin, Cambria, Crainville, John A. Logan and SIU Police Departments, U.S. Fish and Wildlife, Illinois State Police and special agents from the FBI and U.S. Marshal’s Service assisted with the matter.
