WILLIAMSON AND FRANKLIN COUNTIES, Ill. — A bizarre chain of events has investigators looking for answers.

It all started Monday morning around 10 a.m. Williamson County Sheriff's Deputies were called to a home on Gosnell Road, just outside of Hurst, Illinois, where 55-year-old Dennis Hahn allegedly ran over his daughter 33-year-old Mary Halleran with his truck.

"Turns out the driver of the vehicle is the father of the person he hit," said Captain Brian Thomas with the Williamson County Sheriff's Office.

Hahn also pistol-whipped his son-in-law, 27-year-old James Halleran and fired shots into their home. Authorities said Hahn fled the Williamson County scene before they arrived.

Then Franklin County deputies got reports of shots fired along Chamness Road, just off Highway 149. Investigators believe 55-year-old Dennis Hahn went to the home of his son, 37-year-old Dennis Hahn Jr., where a fight broke out.

A family member who didn't want to go on camera said Dennis Hahn Sr. threatened to kill his son's family and for a time, the family hid in the basement of a home.

Franklin County investigators said Hahn shot his father.

Then 57-year-old Betty Hahn got back in her husband's truck and drove to her daughter's home near Hurst.

Mary Halleran was airlifted to a St. Louis hospital with life-threatening injuries. Family members told Local 6 they had no comment and were leaving town to go be with her.

Dennis Hahn Sr. suffered multiple gunshot wounds and underwent surgery at a local hospital Monday.

Franklin County Sheriff Donald Jones said Dennis Hahn Jr. is in custody at the Franklin County Jail and will be charged with aggravated battery with a firearm.

Both agencies said they are continuing to investigate what happened.
