Sergeant Poo Kong San from the Detective Dog Unit of the Negri Sembilan police contingent headquarters said the German Shepherd dog’s health at that time may have affected its sense of smell.
"After taking the dog around a 50m-radius of the house area, which took about an hour, the dog did not give any reaction, ” he said when testifying before Coroner Maimoonah Aid on Thursday . Asked by Nurhafiza what were the factors that influence the level of detection of K9 dogs according to his experience, Poo said there were several factors including weather, types of topography and the number of people present at the scene.
At the proceedings, the court was also told by the witness that the K9 dog used at that time was four years old and suffered back pain due to age. It was only used for one day on Aug 4,2019.
