MH370 families trapped in 'black hole' one year on

Kuala Lumpur - Chinese businessperson Li Hua suffered a stroke, has considered suicide, and his wife has been hospitalised with heart trouble, all since their daughter went missing on flight MH370.

A Amirtham, a retired Malaysian clinic worker, suffers fainting spells and a lack of sleep and appetite over the disappearance of her only son Puspanathan.

Li Jiuying is tormented by the loss of her big brother Li Guohai and the burden of lying to their elderly mother that he was not on the flight. The mother believes he is tied up with a business dispute.
