How did detectives solve the case of the bloody motel? - Theodore E. Yeshion
Join Officer Stone as he investigates a mysterious motel case filled with twists and turns! When he arrives at the motel, he discovers a chaotic scene in the room rented by Frank Carter, who hasn't been seen for three days. The room shows signs of a struggle, with stains and a shoe print hinting at something serious. To uncover the truth, Officer Stone calls in a detective and a crime scene team to gather evidence. They employ an exciting tool called luminol, which glows blue when it detects blood, even in tiny amounts. As they spray the luminol in the dark motel room, they see glowing patterns that tell a story of what might have happened during the struggle.
The investigators follow the clues illuminated by the luminol, including footprints and a glowing handprint that lead them outside. They even find traces of blood in the parking lot, suggesting that the victim was moved. But luminol can also react to other substances, so they must confirm their findings with additional tests. When a DNA test reveals that the blood belongs to Frank Carter, the mystery deepens. It turns out Frank might be the victim, not the suspect! A breakthrough comes when a local trooper pulls over a driver with blood on their car, leading to even more evidence. With all the pieces coming together, the driver confesses, and Officer Stone's investigation wraps up successfully. This exciting case shows how detectives use science to solve mysteries and uncover the truth!

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.
