Not long after the killings began in Mogilev, Einsatzgruppen B was faced with the task of liquidating the patients of the lunatic asylums in the cities of Minsk and Mogilev in September of 1941. Artur Nebe commander of Einsatzgruppen B sought help from Kripo headquarters in Berlin.
Assistance came in the form of Albert Widmann a chemist at the Forensics Institute in Berlin, who arrived in Mogilev on the 18 September 1941. There he began carrying out gassing experiments at the psychiatric institution, killing at least twenty patients.
