Unlocking Secrets: DNA Clues from Explosive Devices

The Problem

Explosive devices made from everyday items are often used by criminals. Even after these devices go off, tiny bits of DNA can sometimes be found. This DNA can come from:

• Skin
• Blood
• Other body fluids

But, it's often in bad shape and hard to study.

The Study

Scientists conducted a study to see how well they could find and study this DNA. They:

1. Put DNA from different sources on different parts of the devices.
2. Blew them up using different amounts of dynamite.
3. After the explosion, they tried to collect and study the DNA.

The Findings

Many factors affect how well they can study the DNA:

• Type of DNA
• Amount of dynamite used
• Part of the device
• Material it's made of

They also found that:

• DNA from blood was the easiest to study, even after big explosions.
• DNA from skin contact was also found, especially on batteries.

The Conclusion

This study shows that it's possible to find useful DNA clues from explosive devices. But, it's not easy. The results can vary a lot based on many different factors. This information can help forensic investigators in their work.
