On the 19th of January, 1994, Heather Thomson (27) was last seen walking out of Craig Dunain psychiatric hospital. The previous day Heather had checked herself into the facility, after 'feeling down for some while.'
Heather was a mother of a young son only a few months old, and she had previously worked as a hairdressed. She lived in Inverness, Scotland, but she had connections to Edinburgh, Elgin and London. Her parents claimed that while Heather had gone through several bouts of post-natal depression, but had spent a happy christmas with the family in December.
There have been no confirmed sightings of Heather since.
The investigation appears to be at a hault and no progress has been released publically.
Heather Thompson's son, now grown, would go on to attack his father (Gerard Salvadori), believing that he had something to do with his mother's disappearance.
