*When Leanne Tiernan's body was found, the police searched the woods where the body was discovered. During the search police found over 400 items that could relate and help solve Leanne's murder.
*DNA samples were taken from Leanne, her family, friends, the sexual offenders in the area and all the neighbors of Leanne. None of the DNA samples matched any of the items found near Leanne's body in the woods.
*The scarf placed around Leanne's neck had a few strands of hair caught between the knot tied. The hair found in the scarf didn't match Leanne's hair. The DNA found in the hair roots wasn't sufficient enough for standard DNA testing. A small amount of DNA was found in the shaft to conduct Mitochondrial DNA testing. The DNA found matched the DNA of the suspect, John Taylor.
*Investigators found partial dog hairs of the body of Leanne Tiernan. Scientists in Texas produced a partial DNA profile of the dog's DNA. This was the first time the British Investigators tried to used dog DNA profiling in a case. However, the dog DNA could not be used because the suspect's dog had died before Taylor was the suspect.
*The blood found under the floor boards at John Taylor's house was collected and analyzed. DNA tests confirmed that the blood found in Taylor's floor was a match to Leanne Tiernan's blood.
