ACP Hussein told the court that the police forensics team recovered 417 bone fragments, three teeth, two necklaces, two coins, a key, 15 metal pieces and four melted metal believed to be gold at the bottom of Sungai Panchau during a search operation on Sept 15, 2010.
He was the 51st witness in the trial against former lawyer N. Pathmanabhan, 41, and three farm hands, T. Thilaiyalagan, 20, R. Matan, 21, and R. Kathavarayan, 31. The trial has entered its 37th day.
The four are accused of murdering Sosilawati, 47, her driver Kamaruddin Shamsuddin, 44, bank officer Noorhisham Mohamad, 38, and lawyer Ahmad Kamil Abdul Karim, 32.
Blood was detected in soil samples taken from a farm in Banting, where cosmetics millionaire Datuk Sosilawati Lawiya and three others were alleged to have been murdered, the High Court heard.
Police forensics laboratory deputy chief Asst Comm Hussein Omar Khan, 41, testified that police took 65 samples on Oct 9 and 10 last year, and conducted presumptive tests for blood in several layers of the soil at the farm on both days.
With the help of officers from the Mineral, Science and Geology Department, who dug as deep as 90cm, the samples were collected and tested using Hemoccult Sensa test cards (a type of test kit for blood) at the scene.
