HUTCHINSON— The case of a teen charged with two counts of first-degree murder, attempted murder and aggravated arson was before a judge Monday morning where a trial date was set.

Samuel Vonachen is accused of setting a fire to his family’s home that killed his mother and sister.

He was 14 at the time and the state has charged him as an adult for those crimes.

The trial date was set for Aug 22, after a defense request to suppress the video interview officers did with the defendant where he allegedly confessed to the crimes was denied.

The case centers on Vonachen allegedly spreading gas through the downstairs of his family’s home, then setting it on fire on Sept. 26, 2013.
