Monthly Mystery: College Crime - Part Two

Concluding his lecture on "Introduction to Effective Communication" for first-year students at Oddtown Heritage College at precisely 12:30 pm, Mr. Links remained in the now-deserted lecture hall to review assignments. At 1:03 pm, he proceeded to his office. A realization struck him at 1:18 pm – his briefcase, containing the upcoming week's exam paper for second-year students, was inadvertently left behind. Swiftly retracing his steps to the lecture hall, Mr. Links discovered the briefcase, seemingly untouched, and upon inspection, found that nothing was missing, including the crucial exam paper. However, a perplexing discovery awaited him – the exam paper wasn't precisely where he had initially placed it. It had been extracted from the designated folder and discreetly repositioned in a different one. It became evident that a second-year student had clandestinely infiltrated the lecture hall after Mr. Links and the first-year students had departed, taking an illicit peek at the upcoming exam questions. Now tasked with crafting a new exam paper, Mr. Links is unwavering in his determination to unearth the identity of the student who committed this academic transgression.
