GCSEase Incriminating Evidence

Summary

The script details a crime scene investigation following a man's critical injury. Scene of crime officer Simon Pole and his team meticulously gather evidence, including shoe prints, weapon traces, and fibers. A crucial breakthrough comes from matching fingerprints and DNA found at the scene with suspects, leading to their identification. The use of forensic tools like electrostatic lifting, UV light, and chromatography aids in linking the suspects to the crime, ultimately resulting in their arrest for aggravated burglary.

Takeaways

• 🚨 A man was rushed to the hospital in critical condition on June 26th, triggering a crime scene investigation.
• 👮‍♂️ Scene of crime officer Simon Pole was called to investigate and preserve the crime scene.

• 📸 Crime scene photographer Paul Canning was enlisted to record the shoe marks and other evidence.
• 🏡 The crime scene revealed a baseball bat and a pair of glasses with fibers, suggesting a struggle occurred.
• 👓 Fibers trapped in the glasses hinge were inspected, potentially linking to a suspect.
• 🔍 The use of oblique light and electrostatic lifting machine helped in lifting shoe marks from the carpet.
• 🧬 Fingerprints were dusted for and lifted using cell tape, to be compared against the police database.
• 🔬 A handprint was revealed on a wall using a crime scope with ultraviolet light.
• 🔩 A crowbar and a pair of shoes were forensically compared to evidence from the scene.
• 🌿 Pollen found on a suspect's jumper matched that of the victim's living room, placing the suspect at the scene.
• 🧪 Dye chromatography was used to match fibers from the crime scene to a suspect's clothing.

Q & A

What event triggered the investigation in the script?

A man was rushed to the hospital in critical condition following an assault, which led to the crime scene investigation.

What evidence did the investigators find in the soil near the crime scene?

The investigators found a visible shoe print indented in the soil, which was later carried onto the carpet inside.

How was the shoe print on the carpet lifted for analysis?

The shoe print on the carpet was lifted using an electrostatic lifting machine that drew the dust out of the carpet to reveal the print.

What technology did investigators use to detect a hidden hand mark on the wall?

Investigators used ultraviolet (UV) light from a crime scope to reveal a hidden hand mark on the wall.

How were fingerprints collected from the scene?

Fingerprints were collected by applying aluminum powder to surfaces and using adhesive tape to lift the marks, which were then preserved on a clear plastic sheet.

What was the significance of the crowbar in the investigation?

The crowbar, recovered from a second suspect, was forensically analyzed and matched to marks found at the crime scene, confirming its use in the burglary.

How did the investigators link the suspect's shoe to the crime scene?

The investigators compared the wear and damage patterns on the suspect's shoes with the lifted shoe print from the crime scene, confirming a match.

What role did pollen play in the investigation?

Pollen found on a suspect's jumper was identified as lily pollen, which matched the lilies in the victim's living room, placing the suspect at the crime scene.

How did the investigators use DNA to identify the attacker?

DNA was extracted from the toothpick of a Swiss army knife found at the scene. The DNA matched the second suspect, confirming his involvement in the stabbing.

What were the final charges the second suspect faced after forensic evidence was gathered?

The second suspect faced charges of aggravated burglary and a longer sentence due to the evidence linking him to the stabbing and use of the Swiss army knife.
