While Högel was imprisoned, a woman came forward and stated that she believed he had killed her mother. This lead to a new investigation, which determined that Högel had killed patients at the hospital he worked at. Högel himself admitted to having killed 30 patients by administering a lethal injection. He is now believed to have possibly killed up to 300 patients this way. On the 6th of June 2019, Högel was convicted of murder and sentenced to life imprisonment.
