The exact number of his victims is unknown. He was convicted of two murders and was scheduled for a trial for his third murder trial when he committed suicide in his cell. He can be linked to seven other identified murder cases, but most of those happened during his exile in Siberia and are poorly documented, so his involvement is not certain. It is claimed that he confessed to 18 murders, but there are no details about this supposed confession, and the figure should be regarded as unreliable. Some sources estimate his total number of murders as 22–25. He also non-fatally wounded at least six men in knife fights.

However, it is not known whether he was referring to rapes or cannibalization, nor is it known if the statement was truthful. He was a suspect in at least five murders during his lifetime. Fish confessed to three murders that police were able to trace to a known homicide, and he confessed to stabbing at least two other people.
