A former safety officer, who side-swiped a lorry and hit the back of a stationary bus trapping his wife in the front passenger seat, was jailed for six weeks on Tuesday for causing his wife's death by negligence.

Bobby Elfian Mokhtar, 29, was also banned from driving for six years for causing the death of his wife, Ms Siti Norliza Mohamed Hamid, 25, by negligence and drink driving along Raffles Boulevard at 8am on April 1 last year.

The court heard that the father of two did not have proper control of his Toyota Vios car, causing it to veer to the left and side swipe against a stationary lorry on the extreme lane. The car then lurched forward and hit the back of a stationary SMRT bus.

The impact caused the front of the car completely caved inwards. Ms Siti Norliza was trapped at the front passenger seat with an open wound across her abdomen. The bus had to be moved forward and left car door pried open to extricate her. She was pronounced dead at the scene by paramedics at 8.22am.

Further investigation showed that Elfian had about four glasses of whisky with his friends at Yumico KTV at Sultan Plaza around 12.30am. He left to meet his wife at Orchard Towers between 5am and 5.30am.

In sentencing Elfian, District Judge Lim Keng Yeow said the accident was unfortunate but it was also one that arose from choices and actions of the offender that were inexcusable, even reprehensible.
