A court has been told that Gardaí are still awaiting post mortem results and a toxicology report on a woman who died in a house fire in Doochary before any further decisions can be made in the case.
The remains of a woman in her 80s was found at the house following a fire on April 12th last.
Her son, German national Guenter Lohse, was arrested a short time later and has been in custody since.
The 61-year-old is currently in custody in Castlerea Prison having been charged in connection with the fire, which resulted in the death of his mother.
Lohse is charged with arson with intent to endanger life.
Those results will help to determine the course of a criminal case involving Guenter Lohse.
He appeared via video link from Castlerea at Letterkenny District Court.
No German interpreter was present for the brief hearing.
Sergeant Jim Collins told the court that a post mortem report and a toxicology report remain outstanding. Directions from the Director of Public Prosecutions will follow the submission of those reports.
At a previous sitting of the court, a judge granted a request to have a clinical psychologist carry out assessments on Lohse.
Judge Alan Mitchell remanded Lohse in custody to appear, via video link, before the August 18 sitting of Letterkenny District Court.
