SYRACUSE, N.Y. (WSYR-TV) — The Onondaga County Sheriff’s Office believes a deputy knew he was about to get caught with stealing more than $500,000 when he murdered his son, shot his wife and killed himself in February.

At the time of the shooting, Deputy Isaac Eames had been questioned about a single failed bank transfer from the Sheriff’s Office account he managed to a personal account he shared with his wife, Karen Eames.

Investigators have since discovered made 13 successful transfers totaling more than $500,000.

Onondaga County Sheriff Gene Conway said that, in short, Isaac Eames “was internally committing thefts over a period of time.”

Karen Eames, a beneficiary of the community’s prayers after she was shot, survived but is accused of being part of the scheme.

On behalf of her deceased husband, the surviving Eames is accused of spending $300,000 of the stolen money on new home construction, cars, gambling and travel.

She’s charged with grand larceny and possession of stolen property.

Karen Eames was arraigned on the charges Thursday night at the Onondaga County Criminal Courthouse. Her defense attorney, Michael Vavonese, said, “I sincerely hope that as we go through this, we find that there is some misinterpretation or confusion of events.”

Eames plead not guilty and is allowed to be released from jail until her next court appearance.

The Sheriff’s Office now has two people manage the account, a sergeant and a non-sworn staff member.

Sheriff Conway also said that he was “very comfortable” saying that the murder-suicide was due to the investigation, but that the entire course of events was “a slap in the face to me.”
