The scene examination at the Birkenhead-Glenfield cemetery is expected to be completed by tomorrow.
Senior Sergeant Stan Brown said there is a still a lot of work to be done by the enquiry team in the next few weeks, including statements taken from the vast number of people who have provided Police with information over the past few days.
Investigators have now confirmed that Mrs Gotingco did take the 973 bus from Lower Albert Street to Birkdale, just after 7pm on Saturday night.
The enquiry team is still looking to speak to anyone who travelled on that bus.
The 0508 number is still open and more than 50 calls have come into the enquiry team today.
Anyone who believes they may have information is still encouraged to make contact with Police via the 0508 number.
As the investigation continues Detective Senior Sergeant Stan Brown says the welfare of the Gotingco family is a priority.
"Our thoughts are with Blessie's family at this very difficult time and their ongoing care and welfare is paramount.
We'd like to reiterate their request, please allow them the time and space to grieve as they deal with this."
A post-mortem examination will be carried out today.
