THE horrifying final moments of 32-year-old Smaelmeeral Abdul Aziz before she fell to her death in July last year were reconstructed in the High Court on Wednesday.

From the bloodstains, shoe prints, and broken shards of costume jewellery, senior forensic scientist Michael Tay traced her painful journey from the bus stop in Stirling Road to the 13th floor of Block 181 about 15m away.

She had been assaulted at the bus stop and an analysis of the bloodstain pattern revealed that her bleeding got worse as she moved to the lift landing.

On the way, she either spat out a broken tooth or was hit in the face to dislodge it.

'At the lift lobby, there was a considerable amount of bloodstains on the lift doors,' observed Mr Tay.

She was pulled into the lift and was either punched, slapped or kicked as it went up.

The blood splatter indicated that the victim was practically lying helpless on the floor.

She bled heavily there and the bloody shoe prints of her attacker started trailed from there.

On the 13th floor, the assailant moved her rather quickly to the common corridor as seen by the scattered blood drops on the floor.

Then, she was hurt again, this time more seriously before her fatal plunge at about 4am.

Her husband, Tharema Vejayan Govindasamy, 40, who is being tried for murdering her, is claiming diminished responsibility as he had been a victim of a black magic spell cast by her family.

He is a Hindu while Madam Smaelmeeral, a factory production operator, was a Muslim.

Mr Tay said she was severely beaten before her death, from the hair strewn about at the murder scene.

'These strands were blood-soaked and there were also broken pieces of costume jewellery,' he said.

During the trial in August, housewife Nancy Loh, who lives on the 13th floor, testified that she heard loud groaning and banging coming from the common corridor.

It sounded just like someone's head being hit against the wall and the groans were 'very loud and very scary', she had told the court.

Mr Tay doubted Madam Smaelmeeral had stepped on a flower pot to climb over the 1.22m-high parapet railing to throw herself down. Rather, her attacker could have lifted her over the parapet railing and tipped her over, he said.

She was bleeding heavily and there were drops of her blood all the way down to the 1st storey parapet.

When she fell over, her body dented one of the National Flag hooks on the outside of the parapet wall.

She hit the ground with her hip, sending blood splattering more than a metre high.

Cross-examined by Mr Glenn Knight, who is representing Tharema, Mr Tay agreed that the shoe prints could have been made after Madam Smaelmeeral had fallen to her death.

The trial, which is in its 17th day, continues on Thursday.
