The CBI had claimed that Aarushi and domestic help Hemraj had suffered grievous injuries after being hit on the head with a golf stick.
"In Aarushi's post-mortem report, line fracture was mentioned as injury number 1 (forehead). If a person is hit with a rod or hockey stick, it would cause such a fracture, while a depressed fracture is inflicted if a golf stick is used," Sharma, a witness for the dentist couple Rajesh and Nupur Talwar, said while deposing before Additional Sessions Judge Shyam Lal.
"The cuts on Hemraj and Aarushi's throats were similar. The cut on Aarushi's throat was 8cm x 6cm. It is wrong to say that a khukari (a Nepalese knife) used with full force cannot inflict a deep slit on a throat. It depends on the force. Small sharp-edged weapon can make long cuts, but injury's depth will depend on blade's length, and it will be equal or less than the blade's length," he added.
"It is wrong to say that horizontal injuries cannot be made with khukari," Sharma told the court.
