Police were originally on site for another reason but became suspicious of the father and later found a long series of 3D-printed weapon parts. The parts could be assembled into a submachine gun, and in addition to those, two single-shot pistols and ammunition, as well as manuals for weapon manufacturing, were discovered. Both the father and son have denied the crimes, but the father was sentenced to four years in prison for, among other things, serious weapons offenses, while the son received a prison term of two years and four months.
The original reason police were on site has not been disclosed, and the specific charges included in the father's conviction for serious weapons offenses remain unclear, as do the details of the son's specific charge or conviction. It is also unknown when and where the trial took place, and what evidence led to the convictions despite the denials.
