SINGAPORE - The 23-year-old man who stabbed four women, killing one, as part of a morbid sexual fantasy he harboured since he was in primary school, was put behind bars for life on Thursday.
Soh Wee Kian had to be jailed for a lengthy period "for the sake of the public and for your own good", Justice Choo Han Teck told the full-time national serviceman, who stood expressionless.
Prosecutors had argued that the violent nature and number of his offences showed that Soh was mentally unstable, and likely to commit the same crimes. But because of his mental condition, he was also spared caning.
Mr Ng Kak Joo, the widower of the 32-year-old mother of two who was killed, said that the case had been one disappointment after another - first Soh was spared the noose, and now, the cane.
"The one who did not deserve to die, died; and the one who did, lived," said the 42-year-old in Mandarin, adding that he had a son in Primary 6 and a daughter in Primary 2.
Soh had been originally charged with the 2010 murder of Madam Hoe Hong Lin in Woodlands. But it was reduced to culpable homicide on the basis that he will plead guilty and that the prosecution will seek a life term.
On Tuesday, he also admitted to causing grievous hurt with a weapon for stabbing Madam How Poh Ling, 28, in Sembawang. Two charges for slashing two other women were taken into account.
He carried out his reign of terror over a span of nine months in 2010, culminating with Madam Hoe's death. His DNA was found on the knife sheath he dropped at the scene.
