Challenge Interrogating Case Study

Another challenge interrogators face is their struggle to avoid contaminating the confessions. By now we can determine that it’s evident that a confession is contaminated when questions are asked that use specific crime scene data and results. For example, crime scene photos that were not made public may be shown to the suspect. In these cases, a confession can no longer be considered valid because the suspect may have become more knowledgeable on the crime through the interrogation and simply repeats information learned. As a result, it could appear that the suspect offered a confession when their interests were motivated by a desire to end the interrogation. Therefore its extremely vital to preserve all evidence on hand.
