Finding the Suspect

Gordon Hays teeth impression model

Impression number 11

One of the first places investigators checked was a local school for problem teenagers.

Gordon Hay was a student at the school because he was arrested for breaking into a factory

Hay lived with two other boys who, along with other witnesses, lead investigators to suspect Hay as the murderer

First Impressions

Many boys attending the school were asked for teeth impressions, as well as Gordon Hay who agreed to have them taken and denied any involvement in the murder.

Impression number 14

Around 29 impressions were taken and given to Dr. Warren Harvey to match to the bite mark

Shortly after receiving witness statements of seeing a boy and a girl in the cemetery and hearing screams Harvey was able to narrow the impressions down to 5 possible matches

This is the upper half of Gordon hays teeth

Conclusion

and the bottom teeth which show some of the individual characteristics

17 year old Gordon Hay was convicted of the murder of Linda peacock February 26, 1968

What Happened?

Matching Evidence

To narrow down the 5 remaining impressions Keith Simpson joined the case.

  • August 7th, 1967 fifteen year old Linda Peacock was discovered dead in a grave yard.

Harvey and Simpson discovered individual characteristics in an impression which had pits in the right-side canines.

investigators were able to prove the bite mark belonged to him and was not caused by any other object.

The impression belonged to Hay and the pits were the result of a condition determined to be hypoplasia.

  • She had gone missing just one day earlier from her home in Biggar, Scotland.

These matched the bite found on the victim.

The mark left after Hay strangled the victim.

  • she was strangled and had a bruise on her right breast

The Evidence

- A bite mark found on the victims right breast

-lacerations and burn marks

other evidence such as the lacerations and chord found at the crime scene also helped to convict Gordon Hay.

- The string Hay used to strangle the victim was hanging from a tree
