HUTCHINSON -The trial for a Kansas teen accused of the murder of his mother and sister will continue on Monday

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 on Sept. 26, 2013.

The defense for Vanochen will continue to call witnesses on Monday. They are attempting to show the teen has a mental defect that caused him set the fatal fire.

Last week a psychologist for the prosecution told the court that his evaluation of the teen indicated Vanochen was capable of forming the intent to commit murder and intentionally poured gasoline in the family’s home and set it on fire.

On Friday, after the state rested their case, the defense asked for a judgment of acquittal, which was denied.
