Terry Ogle, a former middle school teacher from Indianapolis, calmly confessed to killing his wife with a hammer in a chilling 911 call, telling dispatchers he believed she was having an affair and had 'lost it.' Now the 79-year-old is headed to prison — but not for murder.
Background
Mary Ogle, 76, was found dead inside the couple's Indianapolis home on Jan. 17, 2025, after Terry Ogle called 911 to report 'there's been some violence,' according to court records reviewed by Law&Crime and reporting from local Fox affiliate WXIN. When dispatchers asked if he wanted them to send help, Ogle responded with a disturbing calm: 'I did it. Yeah, she's been down for a while.'
When Indianapolis Metropolitan Police arrived at the residence, Mary Ogle was discovered lying on her back, covered with a blanket and bleeding from a severe head wound. She was pronounced dead at the scene by Indianapolis Emergency Medical Services personnel.
Terry Ogle was also bleeding upon police arrival — authorities later determined he had inflicted a wound to his left wrist. He was transported to a hospital for treatment while in police custody before being transferred to the Marion County Jail.
Both Terry and Mary Ogle worked in education, according to The Indianapolis Star. Terry Ogle had been a middle school teacher prior to his arrest.
The Investigation
During subsequent interviews with detectives, Ogle provided a motive rooted in jealousy and alleged infidelity. 'I've been under depression for a while,' he told investigators, according to WXIN. 'I think she's having an affair. So, I lost it.'
Ogle also reportedly texted his daughter after the attack: 'I'm going to jail. I killed Mary.' The message provided additional documentary evidence of his admission.
Originally charged with murder, Ogle faced a multiday bench trial in Marion County Criminal Court. In May 2026, he was convicted of voluntary manslaughter — a lesser charge that prosecutors argued fit the circumstances of a killing committed in the 'heat of the moment,' according to WXIN's coverage.
On July 18, 2026, Judge Timothy Oakes sentenced Ogle to 15 years in the Indiana Department of Correction. The sentence reflects the voluntary manslaughter conviction rather than the original murder charge.
Key Takeaways
- Terry Ogle confessed to killing his wife Mary Ogle with a hammer on Jan. 17, 2025, and admitted the slaying during his 911 call
- He told police he killed her because he believed she was having an affair, saying 'I think she's having an affair. So, I lost it.'
- Originally charged with murder, Ogle was convicted of voluntary manslaughter after a bench trial in Marion County
- The conviction reflects the prosecution's argument that the killing occurred in the 'heat of the moment' rather than premeditation
- Both Terry and Mary Ogle had careers in education; Terry was a middle school teacher
- Police found Mary Ogle covered with a blanket at the scene, suggesting post-attempt concealment
What's Next
Ogle is now serving his 15-year sentence in the Indiana Department of Correction. The case represents a notable outcome where jurors — or in this instance, the judge acting as trier of fact — determined that although a killing occurred, the circumstances did not rise to the level of murder conviction. No further court proceedings are anticipated unless Ogle pursues an appeal of his conviction or sentence.
