He worked in some type of health care. I wonder if there have been any deaths at that location. His comments indicated he had killed before.
He was a counselor with a provider of counseling services, sometimes at the homes of clients. The killing happened on East 93rd in Cleveland. There have been a lot of murders on East 93rd over the past few years, but further south than where this happened.
FWIW, this creeps me out. He's a trained counselor. He'd have the skills and ability to lure women into trusting him. Besides that, if he was counseling in people's homes, he'd be a familiar presence in their neighborhoods. I didn't see anything about where he lives, but where he worked isn't that far from where the cluster of murders has been.
