a yellow teck tie aparently used for strangulation
Family friend David Ma claims police told him the tie had been used to kill Mrs Xue, who married her fugitive husband Naiyin Xue, 54, in a simple ceremony at a registry office.

Mr Ma said detectives had informed him of the tie's significance as they asked him if he recognised it. Police would not comment.

This week, New Zealand detectives seized the tie, a martial arts staff and a dressing gown as the search for Xue intensified in the US.
