HUTCHINSON -The trial for a Kansas teen accused of the murder of his mother and sister continued with expert testimony on Thursday afternoon.

Samuel Vonachen is charged with two counts of first-degree murder and aggravated arson after allegedly setting a fire to his family’s home leaving his mother and sister trapped inside. He was 14 at the time of the fire back on Sept. 26, 2013.

Dr. Trever Patton, a Psychologist and an independent practitioner at The Therapy Center in Wichita told the court he did an evaluation on Sam. He testified that the defendant may suffer “Anti-Social Personality Disorder.” When asked by Senior Assistant District Attorney Steve Maxwell if he suffered any type of mental disease or defect? Dr. Patton answered, “absolutely not.”

He also agreed with the state’s arguments that Vonachen was capable of forming intent to commit murder.

The doctor described the teen as being vaguely immature, but extremely intelligent.

Hutchinson Police Detective Paul Sach testified that the defendant basically admitted to starting the fire. Sach was one of the officers who did the video interview with Vonachen.

During the video, Sam was asked why he committed the crimes? “I wanted people to die, people are awful.” said Vonachen. Later, he was told the his mother and sister were gone and that he will never see them again. He was asked during the video interview if that bothered him and he said. “no.”

Bill Hermes, Director of Youth Services in Reno County testified. He oversees the juvenile detention facility where the defendant has been held.

He told the court Sam was very intelligent and rarely interacted with others. He spent most of his day reading or watching movies.

On Friday, the final witness for the state Dr. Shelby Evans, a psychologist who also did an evaluation of the defendant will finish her testimony.
