HINCKLEY TOWNSHIP, Ohio -- The Hinckley Township man charged in the deaths of his brother and sister offered harrowing details of the shooting during a candid phone conversation with a police dispatcher.

Dean Simms, 42, is charged with two counts of aggravated murder in the shooting early Friday on Babcock Road near West 130th Street.

Cynthia Gesaman, 52, and Randy Szychowicz, 45, suffered gunshot wounds to the head and were pronounced dead at the scene, officials said.

The Hinckley Police Department released a recording of the 911 call Simms made shortly after the shooting.

An edited version of the call has been included in this post. Some of the details are graphic.

Hinckley shooting 911

Simms tells a dispatcher he shot his siblings due to a "lifelong of headache."

"I just couldn't deal with it anymore. Now I'm out two siblings," Simms told the dispatcher. "It's not a pretty sight."

Simms says he used a shotgun to shoot his brother and sister and left the gun on the kitchen table.

"I guess I'm going to be going away for life," he said.

Simms agreed to leave the house to meet officers but asked for time to put on pants and shoes.

He said that he wasn't holding any weapons and dismissed the dispatcher's concern that he or officers might be harmed.

"No, I'm done," he said.

A Medina Municipal Court judge set Simms' bond at $10 million during his initial appearance Monday. Simms is scheduled to appear at a preliminary hearing on Feb. 17.

Defense attorney Bob Campbell was not immediately available for comment Monday.

Simms, Gesaman and Szychowicz were living together at the house. No one else was there when the shooting occurred, Hinckley Police Chief Tim Kalavsky said Monday.

Simms' criminal history includes previous convictions for drunken driving and traffic violations.
