Son who found parents' bodies at Cleveland car dealership testifies against accused killer

CLEVELAND (WJW) -- The man on trial for robbing and killing a couple inside their car dealership expressed his condolences to the son of the victims during testimony Wednesday.

Joseph McAlpin, 31, is accused of breaking into Mr. Cars on East 185th Street in April 2017 and shooting Trina Tomola Kuznik and Michael Kuznik in the heads as they prepared to close for the day.

McAlpin, who is representing himself at trial, addressed the victims' son before questioning him during cross examination.

"Even though I understand that scenario of the situation, I want to let you know that I really, for what it's worth, my deepest condolence to your loss, and I don't even know if that will be even enough," McAlpin said. "I just want to let you know that I have my condolence toward you."

Trina's son -- Michael's stepson -- Colin Zaczkowski, who was 19 at the time, went to the car lot and discovered their bodies after the family grew worried because they did not come home as planned. He was the first witness to testify.

Zaczkowski said that when he arrived at the dealership, it was odd that the lights were turned off. He testified that he looked in the showroom and saw that pictures on the wall were crooked, chairs were on their sides and a candy machine was knocked over and broken.

Prosecutors said McAlpin committed the murders, and then he and two other men stole a Mercedes and BMW from the dealership. Jerome Diggs, 24, and Andrew Keener, 25, were arrested and charged with aggravated murder. Keener pleaded guilty to a reduced charge of involuntary manslaughter and grand theft.

Prosecutors said police identified McAlpin as a suspect through DNA evidence found at the dealership and inside the BMW. Investigators said cell phone records place him at the murder scene.

McAlpin was indicted on 25 charges including aggravated murder, aggravated robbery, kidnapping and cruelty to animals.

He was previously served nine years in prison for a 2009 aggravated robbery case. McAlpin faces the death penalty if convicted.
