More than two and a half years after Zdenek Karasek was shot and killed in his home, his son Mark Karasek was sentenced to 17 years in prison for second-degree murder and first-degree unlawful firearm possession on Friday afternoon at the King County Courthouse in Seattle.

Mark, who pleaded guilty last month to shooting his father on Jan. 9, 2015 in their home in unincorporated King County near Redmond, received a sentence of 204 months for murder and 34 months for the weapon charge, which occur concurrently. Mark, who was 22 at the time of the crime, receives credit for time already served.

Sentencing ranged from 154 to 254 months in prison, with the defense team asking for the low range and the state asking for the middle range.

“I just wanted to say I wish I had handled the situation in a different way, and I’m really sincerely sorry that my little brother has to grow up without his dad and without me. I just wanted to apologize to everyone who was affected by this,” Mark told the court on Friday.

Judge John Erlick added before handing down the sentence:

“We’ve heard from everyone, and I know that there are varying different perspectives on exactly what happened and why it happened. I think we can all agree on what’s already been said, which is how tragic this has been for everybody in this room affected by this.

“Record is documented that it was some type of abuse that Mark did experience.”

During the sentencing, Mark’s uncle and cousin spoke highly of Zdenek making a good life for his family through his business accomplishments, and asked for the high-end sentence. Mark’s mother, grandmother and aunt also spoke and asked for the low-end sentence, stating that Zdenek physically and mentally abused his son.

As was previously reported, the father and son had been arguing all day prior to the incident. According to the court report, several individuals in the Karaseks’ home witnessed the two arguing and heard gunshots, though no one actually saw what happened.

Court documents state that at about 5:15 p.m., the father, 51, and son were arguing while the latter’s girlfriend, grandmother and 11-year-old brother were present in the family’s home in the 22000 block of Northeast 75th Street. In addition, two of the suspect’s friends were present.

The documents state that Zdenek “was shot several times and died at the scene.”

According to the documents, Zdenek had told his son to move out of the home, which led to a daylong argument between the two.
