Detective Chief Superintendent Frederick Cherrill was able to match the fingerprint of Cummins's left little finger and thumb with prints found upon the tin opener and broken mirror found near the body of Evelyn Oatley. Cherrill later confirmed fingerprints recovered from two other crime scenes belonged to Cummins. Two of the ten £1 banknotes Catherine Mulcahy's attacker had given her before and after he had assaulted her were brand new. Via tracing the serial number of these banknotes, Detective Chief Inspector Edward Greeno was further able to determine these two notes had been issued to Cummins on 12 February.
