The chemist testifying in the Aminulrasyid Amzah culpable homicide case has admitted to the court that he did not do a reconstruction of the incident and neither did he inspect the crime scene.

NONEShaari Desa (right) admitted that reconstruction and a visit to the crime scene could be vital to the case to determine other factors in the movement of the bullets fired.

Under cross-examination by lawyers M Athimulan and Salim Bashir, the witness, who is also the head of the firearms and detection unit in the Chemistry Department. admitted that he is not a ballistics expert.

Lawyer: Can a ballistics expert reconstruct the crime scene?

Shaari: Yes.

Lawyer: Do you know where and when the incident happened?

Shaari: Yes.

Aminulrasyid was shot dead about 1.30am on April 26, 2010 at Jalan Tarian 11/2, Shah Alam, about 50 metres from the junction to the lane where he lived.

Corporal Jenain Subi, 48, is charged with culpable homicide, and is liable to a maximum of 30 years in jail upon conviction.

Shaari, who had testified yesterday that he does not know which weapon was used in firing the fatal shot, was questioned further about this today.

Lawyer: Do you know who fired the fatal shot?

Shaari: I do not know.

Lawyer: You also do not know how many firearms were used at the scene?

Witness: I agree.

Lawyer: Do you know which weapon discharged the 9mm bullet at the crime scene?

Witness: I do not know, as the 9mm calibre bullet can be used in semi-automatic pistol and also as sub-machine guns.

Lawyer: You also do not know how the shots were fired, where it ended or how it moved, whether the shooter was riding a motorcycle or a car?

Witness: I agree.

Lawyer: You do not know the actual angle of the shot?

Witness: I agree

Lawyer: You do not know the physical location of the suspect or his positioning?

Witness: I agree.

‘Chemist did not analyse fatal bullet’

Lawyer: Did you analyse the pathway of the fatal bullet?

Witness: No I did not.

Lawyer: Did the investigating officer ASP Abdul Halim Ismail inform you that three police patrol cars were involved in the chase?

Witness: I was not informed.

Shaari also admitted that he did not inspect the fatal bullet under an electronic microscope.

He said he obtained the bullet, which was marked "a slug retrieved from a post mortem",  from investigating officer ASP Abdul Halim.

Yesterday, Shaari had testified the slug was missing its jacket which may affect the individual characteristics of the discharge weapon.

Shaari said he agreed he did not re-enact the scene by using the sub machine-gun on a glass pane to simulate a car windscreen.

"I only conducted tests at my office in Petaling Jaya," he said.

He agreed with the lawyers that positioning, and the nature of firing the weapon whether moving or stationary, was vital to his finding.

Shaari said he also did not re-enact the muzzle shots of the sub-machine gun to the target distance and he did not do any fingerprinting on the weapon or bullets used.

He also agreed with the lawyers on the possibility that the slugs from the sub-machine gun could have hit the road first, and ricochet to the bottom of the ill-fated car.

"This may explain the many bullet holes at the bottom of the car," he said.

The witness also said the shots fired below the car could have been directed to stop the car.

Shaari was also asked on the possibility of the uneven road affecting the shooting to the rear of windscreen, to which he agreed on such a possibility.

Shaari: I do not know shot angle

The witness also said he does not know the shot angle, location of the fatal slug, location of the fatal wound, or the physical location of the victim or the shooter.

He agreed with the lawyers that such information could have helped him to refine his conclusion.

Shaari said he got to know about the Aminulrasyid case from the media.

When asked by the lawyers, he agreed that he cannot say 100 percent that the fatal slug originates from a 9mm calibre weapon.

However, on re-examination by DPP Mohd Dusuki Mokhtar, the witness said he could guess this as the "base cup" of the slug measured 8.5 mm.

Shaari also told the court that despite not re-enacting the scene nor visiting the crime scene, he was able to base his findings on theory.

He also told the court he did not analyse the gunpowder residue on the suspect's clothing as it was not provided to him by the police.

"Furthermore, I did not ask for it to be done," he said.

Hearing continues tomorrow.
