The 36-year-old admitted to injecting more patients since April 2017, but denied he intended to kill them. The prosecution requires him to put the unhealthy patients under the gun and then rob them. If he found that he had no valuables, he left his job and happily tried with other elderly diabetes he visits and treats at home.

Since 2015, he has worked in Germany through various Polish and Slovak employment agencies. Police arrested him earlier this year in Munich.
