He reportedly told police he killed her to end her pain and suffering. Gelleny allegedly said he contemplated taking his own life before deciding he would turn himself in.

Detectives serving a search warrant at the home found a note he allegedly wrote detailing what he did. The note also included instructions for taking care of their cat.

Gelleny is charged with first-degree murder and evidence tampering.

His bond was set at $1 million.
