Monica,
From Crown Office Notes of November 1998:
The Procurator Fiscal has a right and a duty to control the disposal of a dead body while he makes enquiries into the death. Depending upon the circumstances he may decide to leave the body where the death occurred, eg at home or in a hospital. He may decide to have the body removed to a police or hospital mortuary or a specially designated mortuary. He will require to decide in every case whether he will accept a medical certificate as to the cause of death and release the body, or whether an autopsy is necessary. When releasing a body the Procurator Fiscal requires to decide whether cremation may be allowed to take place. There may be circumstances, for example a homicide investigation where the Procurator Fiscal cannot allow cremation to take place as it would lead to the destruction of evidence available from the body. If the Procurator Fiscal has no objections in principle to a cremation, the matter then becomes one for the Medical Referee to decide.
In every case in which (a) there is a possibility that the death was caused or contributed to by the commission of a criminal act, or (b) there is a possibility of criminal proceedings in which it will be necessary to prove the fact and cause of death, an autopsy must be carried out by two pathologists.

I suggest that a search of the Sheriff Court records might find details of the investigation or Fatal Accident Enquiry.
