The short definition of robbery is theft from a person by use of force or fear. The level of force does not have to be great to meet the statutory requirement. On the bases of tracking and scaling down robbery crime, the study mock up a situational phenomenon of rubbery operation and envisage a stratagem in crime track and scale down. The study employed voice recognition as a first line of identifying suspect (s) by method of ear witness account. In the phase 1, of the study, close associates and unfamiliar versus total strangers were employed to recognize each other by voice without seeing the persons and followed by matching of blood group, In the phase 2 of the electronic method, phone calls were made to close associates and unfamiliar versus total strangers, with strange phone lines. The results show that close associate tends to recognize each other’s voice more frequently than unfamiliar persons. From the results the percentage reliabilities in voice recognition and blood typing were most reliable among the close associates and least in the unfamiliar versus total strangers. Blood group analysis in conjunction with voice recognized may offer profound reliability on crime solving.
