NEW CASTLE – Two children found dead Thursday in their family’s southwestern Henry County home were shot to death.

Henry County Prosecutor Joseph Bergacs on Friday afternoon confirmed the cause of the deaths of Corrine Nicole Horn, 11, and Thomas Cordell Horn, 5, whose bodies were found by Henry County sheriff’s deputies at 5598 W. Old National Road east of Knightstown.

The autopsies conducted Friday in Marion County also showed the children’s father, Joseph L. Horn, 48, had died of a self-inflicted gunshot wound.

Bergacs, who is the spokesman for the Henry County Major Investigation team, has not specifically said investigators believe Horn — in the midst of divorce proceedings — shot his children, and then turned his gun on himself.

However, on Thursday he said there was “no evidence of any suspects at large.” An officer told The Star Press on Thursday the case was being investigated as a likely case of murder-suicide.

Deputies said when they arrived at the home, they could see, through a window, the body of Thomas Horn on the floor. They entered the house by force, then found the other two bodies.

Corrine and Thomas Horn were both students at Tri Elementary School. The call that sent deputies to their home on Thursday morning was reportedly based on concern they had failed to show up for classes.

On Friday, South Henry Schools Superintendent Wes Hammond said efforts were being made to help their classmates cope with the tragedy.

“We do have additional counseling support available for our students and staff, multiple people from the community and area schools that have volunteered or we’ve contacted,” Hammond said.

Hammond said school personnel had “been working with our students throughout the day, and will continue to do so as needed.”

Joseph Horn’s wife — and the mother of the two children — sued her husband for divorce on Aug. 11.

A review of the Henry Circuit Court 1 case file on Friday revealed nothing that reflected an especially contentious case. Joseph Horn’s spouse did not seek a protective order against him.

A Wednesday afternoon hearing — apparently attended by Horn, his wife and their attorneys — apparently focused on child support Horn would pay while the case was pending. The couple had married in 1998.

Bergacs said evidence collected at the scene will be forwarded to an Indiana State Police laboratory for “testing and analysis.”

The probe by the Major Investigation Team — made up of the sheriff’s and New Castle Police departments, state police and Bergacs’ office — is continuing.
