Details on my role in the presentation

My part of the presentation will mainly focus on three slides. First I will speak about why society blames certain suspects, for example why so many suspects are foreign or have a mental illness and how this was influenced by the state of the society during that period. I will add examples alongside these of suspects who fit the different criteria. The second slide will focus on suspects who were blamed back then and state why they were suspected. For the third slide I will speak about some of the suspects that have came up in recent years and how the advanced technology and findings have helped come to these conclusions while also pointing out the increased difficiulty in finding who the Ripper was as time goes further away from the killings. It will be worth mentioning at this stage that many suspects nowadays are invented or blamed purely to sell books or increase popularity of the accuser rather than provide an honest attempt at solving the mystery. I intend to use the slides as a base from which I can elaborate and describe the points I am making.
