CLEVELAND, Ohio -- Cuyahoga County sheriff's deputies are investigating the mysterious poisoning of a county probation officer's pet goldfish.

The 28-year-old probation officer filed a complaint Feb. 15 that says she went to feed her fish at her office in the Marion Building on West 6th Street and she noticed something odd.

Someone dumped all of the fish food and pellets into the fish bowl she kept at her desk, a report from the sheriff's department says. The fish did not survive.

The officer also told investigators that someone tampered with an apple she had on her desk and that the fish was alive when she left work a day earlier, according to a sheriff's incident report.

A week later, a co-worker called the probation officer and broke the bad news that her new fish also died, the report says. Someone dumped Wite-Out

and hand sanitizer into the fish bowl, killing the fish, the report says.

The probation officer took photos and reported the incident to supervisors and investigators with the sheriff's department. The fish deaths are being investigated as an instance of "workplace violence," according to the incident report.

Sheriff spokesman John O'Brien said the investigation has not yet been completed.

O'Brien said disciplinary action could be taken if the investigation shows a co-worker poisoned the fish. Criminal charges are also possible.
