After more than seven years of search, police finally got a clue on the whereabouts of Li Hau Cao who was killed by his property tycoon husband Robert Ekaireb back in 2006. According to British reports, Li's body was hidden by her husband under one of London Olympics' site with the help of a crime syndicate.

The Sunday Morning Post reported that "Detectives who worked on the case are convinced Li's remains were disposed of on the Olympic Park site as the ground was being prepared for the huge project ahead of the 2012 London Olympics."

The news portal also revealed that the suspect, estimated to have a fortune of £65m, has a complex web of connections with a London crime gang called A-Team or Adams family. This gang is heavily linked to hitmen and multiple murders. The authorities said Ekaireb used his connections to be able to dispose the corpse of her wife in the site where the London's Olympic Park was yet to be built back then.

"It is believed he used his links to an organized criminal network to dispose of Li Hau's body," police said, quoting Scotland Yard detectives.

Li Hau Cao, who was four weeks pregnant when allegedly killed by her husband vanished in 2006 without a trace. Authorities her death was rooted from a simple argument with her husband. According to reports, Li's old work as a dancer and waitress has gotten Ekaireb so jealous to the point that he bought a lie detector for her to assure that she's not receiving any money anymore from patrons.

 "Ekaireb was controlling, restricted her access to money - despite his immense wealth - and often lost his temper," said Deputy Inspector Andy Manning.

"Ekaireb lost control and killed her as they argued on 23 October 2006. He then disposed of her body, cleared up the flat and carried on with his life."
