An elderly couple were found dead in their home, apparently after the woman collapsed and her husband fell while trying to help her. The bodies of the pair, who are believed to have been dead for two or three days, were found after Housing Department staff reported a bad smell coming from their flat in Sham Shui Po. Ma Han-sen, 75, and his wife, Chan Fook-ling, 68, were lying side by side on the living room floor of the flat in Man Tai House, Tai Hang Sai Estate. 'The woman probably tripped over a chair and slumped to the floor, hitting her head, then fell unconscious,' a police officer said after initial investigations found nothing suspicious. 'Her husband, who suffered heatstroke about 10 years ago and had difficulty walking, probably came to help but collapsed on the floor beside her.' The discovery prompted the Social Welfare Department to appeal to the public to show more concern for, and make more contact with, elderly relatives and neighbours. Sham Shui Po district councillor Wong Kwai-wan called for the government to allocate more resources to providing care and services to senior citizens. Housing Department staff carrying out cleaning work in the building called police shortly before noon yesterday after noticing the smell. The security gate and wooden door to the flat were closed but unlocked. Police said there was no sign of a struggle or ransacking of the flat. Autopsies will be carried out today. The couple, who lived on welfare, are survived by two daughters, who moved out of the flat years ago. The Social Welfare Department said social workers were trying to contact them. A spokesman said the public should show more concern and make regular visits to elderly relatives and neighbours to check how they were. He said the department's 41 district community centres for the elderly and 117 neighbourhood centres for old people offered outreach services to elderly people across the city. People could also call a 24-hour hotline on 2343 2255 for help if necessary. Wong said the deaths showed there were insufficient resources to provide services to old people in need of help. She said about 80 per cent of the tenants on the estate were elderly.
