Testifying in the Aarushi-Hemraj double-murder case on Thursday, Rajinder Koul — a friend of Rajesh Talwar — told the special CBI court in Ghaziabad that the Talwars' were in a state of shock when their daughter's murder was discovered on May 16, 2008.
Rajinder Koul, a businessman, was one of the two defence witnesses who appeared before the court on Tuesday. The CBI court had on Tuesday allowed the Talwars — both accused in the case to produce seven of the 13 names they wanted to be summoned in their defence.
Koul was at the Talwars' residence on May 16, 2008. Aarushi was found murdered in the Talwars' Noida residence on May 16, 2008. The body of their domestic help Hemraj was found the next day from the terrace.
Koul said that he saw Rajesh and Nupur speaking to policemen and "they were in a state of shock." Some prosecution witnesses examined by the CBI had earlier claimed otherwise.
Koul, who was also present at Aarushi's cremation, said: "I was present in the house for one hour (after the cremation) and everyone seemed sad and the accused were weeping."
Koul said he heard Talwar's relatives and friends telling the police that the murder weapon could be present at the terrace.
"The policemen looked at the terrace door with a torch light. They said that the door seemed to have been locked for a long time and they will have a look next morning," Koul said.
Another defence witness, Amulya Chaddha, told the CBI court that final-year students of Bachelor of Dental Surgery are taught to use the scalpel.
Blades are of different numbers.
"A dentist uses blade number 15 for oral surgery and its use is taught during course study," Chaddha said.
During his cross-examination by CBI special public prosecutor RK Saini, Chaddha said. "Gums are cut with the tip of the blade. This tip is very sharp... If the blade is put to other parts of the body, it cuts that part," he said.
The CBI claims that a sharp instrument could be one of the possible murder-weapons.
