Scanning the crime scene, Officer Stone sees a disorderly room, visible red-brown stains and a partial shoe track— all hinting at a bloody struggle. After calling in a team to inspect, photograph, sketch, measure, and collect all the evidence, the investigators apply Luminol. So, what is Luminol and why is it used at crime scenes? Theodore E. Yeshion shines a light on the investigative tool. [Directed by Raghav Arumugam, Jagriti Khirwar, narrated by Jack Cutmore-Scott, music by Salil Bhayani, cAMP Studio]. 警官斯通在勘查犯罪现场时，看到的是一个杂乱无章的房间、明显的红褐色污渍和一枚残缺的鞋印——所有这些都暗示着这里曾发生过一场血腥的搏斗。在召集团队进行检查、拍照、素描、测量并收集所有证据后，调查人员开始使用鲁米诺。那么，鲁米诺是什么，为什么要在犯罪现场使用它呢？西奥多·E·耶希恩（Theodore E. Yeshion）为我们揭示了这一调查工具的原理。
