As stated by Detective Inspector Scott Beard, Auckland City CIB:
Police investigating the murders of Fuk-Fu Joseph Kwok and Mei Han Chong are today in a position to provide further information.
A post-mortem on Mei was completed yesterday and found she died from blunt force injuries to her head. This news is understandably distressing to her family, in particular Mei and Joseph's son.
Mei was a 5-foot-tall, 67-year-old woman, weighing no more than 45 kilograms. It is beyond comprehension for the family as to how something like this could happen to Mei and Joseph.
The Police investigation has been fast-moving and led us to numerous scenes across a large part of Auckland. In recent days, Police have executed search warrants at a number of addresses and seized two vehicles we believe are linked to the murders.
CCTV has helped us to identify the suspicious activity of a vehicle and two people at and around the scene in Celtic Crescent, Ellerslie between 1.08am and 3.47am on Sunday 5 November, including the victim's car leaving the address at 3.47am.
Police now know the two vehicles, including the stolen family car were together driving around the Ellerslie area for some time, and ask if anyone saw them to please contact Police.
We still want to hear from anyone who saw suspicious activity or the victims' blue Kia Rio car around Kereru Grove in Greenhithe or Hall Road in Glenfield, any time between the early hours of Sunday November 5 and Thursday November 9.
