Despite the grisly circumstances, the situation is not being treated as a homicide.
Police remain tight-lipped on shoe details
The Herald has asked for any identifying details of the shoe, including a photograph, that could be shared publicly in the hopes of bringing forward people who could help the investigation.
However, no images have been provided. A request for the size of the shoe has also been declined.
It is also not known whether pathology tests on the foot have been completed.
