- Police found evidence including a semen smeared sheet of linen and other incriminating items buried in the field.
- This sheet with DNA evidence on it was from an earlier burglary in which he cut out the sheet so that the police could not find him.
- In all of his burglaries, Malcolm Fairley, would commit violent sexual crimes against females in the Leighton Buzzard area. There is a possibility that he was able to hide his DNA from other houses.
- A popular form of DNA analysis is gel electrophoresis. The DNA evidence is separated by certain enzymes. The separated sequences are then put in a gel which is then electrically charged. DNA has a negative electrical charge so they are attracted to a positive charge when given an electrical current. The DNA sequences then show up to me matched.
- PCR or polymerase chain reaction is when a target sequence of DNA is duplicated until the target sequence can be analyzed and compared.
- Both of these methods could have been used to convict Malcolm Fairley
