HUTCHINSON— The judge in the case of a Kansas teen accused of killing his mother and sister will only allow the state to show one picture of the victims at trial, which begins next week.

Samuel Vonachen who is now 17, is accused of setting a fire to his family’s home that killed his mother and sister. He was 14 at the time.

District Judge Trish Rose in stating that only one photo can be shown is allowing that to help with the medical testimony at trial, but deems the rest as too prejudicial against the defendant.

The defense had asked for more information on the evaluations from two psychologist, which they claim is too vague on how they came to their opinions and conclusions.

The judge denied the request.

On Monday, the defense asked for reconsideration, but Judge Rose stuck with her earlier ruling.

The state was also granted permission to endorse additional witnesses for the trial with no objection from the defense.

Jury selection will begin at 9 a.m. on Monday Aug. 22.

Opening statements could begin Tuesday morning. The trial is expected to last at least a week and a half.
