'David Cohen' / Nathan Kaminsky

Verified background

Biographical facts with sources.

• Retrieved Violent Colney Hatch patient who, per Casebook, was committed at about the time the murders stopped. ○ Weakly supported claim: Martin Fido proposed that the violent asylum patient 'David Cohen' (committed to Colney Hatch around the time the murders stopped) was the Polish Jew suspect, possibly identical with Nathan Kaminsky; the identity is conjectural.[1][2]

Opportunity and timeline

Where the person is documented to have been, and where the record is silent.

• Inference Undocumented. ○ Weakly supported claim: Martin Fido proposed that the violent asylum patient 'David Cohen' (committed to Colney Hatch around the time the murders stopped) was the Polish Jew suspect, possibly identical with Nathan Kaminsky; the identity is conjectural.[1][2]

Strongest supporting evidence

The best case proponents can make from the record.

• Inference Fits the timing of the murders' end and Anderson's description (Fido). ○ Weakly supported claim: Martin Fido proposed that the violent asylum patient 'David Cohen' (committed to Colney Hatch around the time the murders stopped) was the Polish Jew suspect, possibly identical with Nathan Kaminsky; the identity is conjectural.[1][2]

Strongest contradictory evidence

Evidence that tells against the theory.

• Retrieved The Cohen=Kaminsky name-change is conjecture; no police source names him. ○ Weakly supported claim: Martin Fido proposed that the violent asylum patient 'David Cohen' (committed to Colney Hatch around the time the murders stopped) was the Polish Jew suspect, possibly identical with Nathan Kaminsky; the identity is conjectural.[1][2]

Disputed and missing

Points in dispute, and records that do not exist or were not found.

• Retrieved Committal date 7 vs 12 December 1888. ○ Weakly supported claim: Martin Fido proposed that the violent asylum patient 'David Cohen' (committed to Colney Hatch around the time the murders stopped) was the Polish Jew suspect, possibly identical with Nathan Kaminsky; the identity is conjectural.[1][2]

Assumptions required

What a reader has to accept for the theory to work.

• Inference Would require evidence beyond proximity, illness, later violence or a relationship with a victim — none of which is itself evidence of guilt. ○ Weakly supported claim: Martin Fido proposed that the violent asylum patient 'David Cohen' (committed to Colney Hatch around the time the murders stopped) was the Polish Jew suspect, possibly identical with Nathan Kaminsky; the identity is conjectural.[1][2]

What would change the assessment

Evidence that, if found, would move the picture.

• Inference Documented presence at a scene, or a forensic or reliable witness link, would strengthen; documented absence would eliminate. ○ Weakly supported claim: Martin Fido proposed that the violent asylum patient 'David Cohen' (committed to Colney Hatch around the time the murders stopped) was the Polish Jew suspect, possibly identical with Nathan Kaminsky; the identity is conjectural.[1][2]
