Bloodstains: Fire's Unyielding Clues

You might think a fierce fire would destroy all traces of a crime. But bloodstains are surprisingly resilient. Researchers set blood droplets on various surfaces and heated them up. While the droplets changed shape, crucial details like where the blood landed and the angle it hit the surface remained the same. This means even after a fire, bloodstains can still reveal valuable information to detectives. It's like having tiny, heat-resistant witnesses. Isn't that cool?Imagine a fire sweeping through a building. You'd think all clues would be gone. But no, bloodstains stay put and keep their secrets. These tough little clues can help investigators figure out what happened, even when everything else is charred or destroyed. Scientists found out that heating doesn't change the key details about bloodstains. So, even after a fire, detectives can piece together the puzzle of a crime. There's a reason bloodstains are so important. They can show where a person stood, how they fell, or where they might have been injured. Even though fire changes blood droplets' shape, these details stay the same. This gives investigators a key piece of the puzzle they need to solve a case. It's like the bloodstains tell a story that fire can't erase.
