A woman and her three-year-old son were killed after they fell from the 32nd floor of Kiara Residence 2, Bukit Jalil here at about 2pm today.

The bodies of the 23-year-old woman and the boy were found at the first floor landing.

Cheras police ACP Chong Kok Sin said her husband told police that she was suffering from depression.

"Her husband, aged 28, a real estate agent, had once brought his wife to get psychiatric treatment at Universiti Malaya Medical Centre (UM) sometime in May or June. According to her husband, she had always said she wanted to commit suicide," he told reporters here Tuesday.

He said just before the incident, his wife had informed her husband that she wanted to throw some rubbish and that the family was preparing to make a trip to Karak, Pahang.

"She had brought her son along. After about five minutes, the husband asked his daughter to join them at the parking lot while he packed the bags.

"He then heard loud thuds and when he looked down from the corridor of his unit, saw their bodies sprawled on the first floor landing," he said, adding the woman and her son were believed to have fallen from a lounge for residents at the floor which had four-metre high sliding glass windows.

The bodies were sent to the UKM Medical Centre for post-mortem.
