District Attorney Keith Schroeder has announced that a formal complaint has been filed in the Reno County District Court charging 14-year-old Sam Vonachen with two counts of murder in the first degree relating to the deaths of his mother and younger sister. Each murder count is charged in the alternative under the theory that the killings were premeditated or occurred during the commission of an inherently dangerous felony. He’s also charged with the attempted Murder in the first degree for his his father and aggravated arson.

Schroeder says he anticipates that Vonachen could make an appearance at a detention hearing on Monday in Division IV, which is Juvenile Court. The hearing will probably be closed to the public under state law since he is charged as a juvenile offender. He is being held in the Reno County Youth Services Detention Facility.

Schroeder now says his office will seek authorization to try Sam Vonachen as an adult.

This involves the fire which was reported at 4 East 19th around 12:17 a-m. When crews arrived, the two story home was fully involved including the front porch. Once they got the flames under control, they then began the search of the home and found the two victims. neither was conscious at the time.

Schroeder said a news release Thursday evening that investigators determined an accelerant was poured in several rooms on the first floor of the house and intentionally ignited.

Fire officials say the mother and daughter were found dead together in a bedroom. The girl died shortly after the fire and her mother died later Thursday. The boy and his father were unharmed.

The charges against Sam Vonachen, and other released information, are based on mere accusations and he is presumed innocent until and unless proven guilty.
