Study Notes
DNA Transfer
- The average human sheds enough skin cells to cover a football field in two minutes.
- DNA can transfer multiple yards through saliva in 30 seconds.
- A sneeze can deposit DNA onto nearby walls.
- DNA was found on 91% of 105 public items tested, including escalator rails, public toilet door handles, shopping basket handles, and coins.
- The presence of DNA on personal items like the armpits of shirts can be from other people.
DNA Transfer in Forensic Investigations
- DNA transfer can make innocent people potential suspects in investigations.
- DNA mixtures can be misinterpreted and lead to false conclusions.
- DNA analysis robots have limits and their sensitivity can lead to false identification.
- Advances in technology have made DNA analysis more sensitive but also increased the risk of DNA transfer.
Lukis Anderson Case
- Lukis Anderson was charged with murder despite having a hospital alibi.
- DNA evidence placed him at the crime scene, even though he was in hospital at the time of the murder.
- The prosecution theory was that paramedics transferred Anderson's DNA to the victim's fingernails.
- DNA transfer can occur during interactions like shaking hands or dragging someone by the ankles.
- Anderson's case highlights the potential for DNA transfer to wrongly implicate people.
- Most crime labs do not regularly and robustly study secondary DNA transfer.
- The case of the Phantom of Heilbronn demonstrates how contamination can occur prior to evidence arriving in a lab.
Contamination
- DNA was found on three quarters of crime scene tools, including cameras, measuring tapes, and gloves.
- DNA contamination can occur in the lab, even in clean areas.
- Case files can also be sources of contamination.
Other Cases
- The Kumra murder case involved multiple suspects, including Austin, Garcia, and Drummer.
- Garcia's attorney argued for DNA transfer, suggesting his client's DNA was at the scene due to a borrowed box of gloves used by his cousin.
- Prosecutors believed Garcia's DNA was transferred to the crime scene by Austin picking up Garcia's cousin.
- Garcia, Drummer, and Austin were convicted of murder, robbery, and false imprisonment.
Lukis Anderson Case Conclusion
- Anderson is considered the clearest known case of DNA transference implicating an innocent man.
- DNA transfer is not considered a common occurrence in forensic science.
- Experts caution against overreliance on touch DNA for solving crimes.
