"The woman died in hospital at 10.40am on Thursday. Her next of kin have been informed. Formal identification awaits. A post-mortem examination will take place."
Tragically, Boor is believed to have got engaged less than a fortnight ago to her partner of four years Andy Murgatroyd.
It has also emerged Boor's father Matthew Boor is a bricklayer who has been in the industry for 20 years. A fundraising page has been set up by his employers.
Building firm Maytrix Construction created a JustGiving page in a bid to raise £20,000 ($39,000) to help Matthew Boor and his family.
Before her death, a friend told the Evening Standard: "Her family are devastated, we all are. She has ended up fighting for life in hospital on her 29th birthday.
"We had seen pallets of bricks wobbling up there, it was just not safe. It could have been any of us. The family and all of us want answers."
Michaela (aka Kayla) Boor, who recently got engaged, had apparently just dropped her son off at school before walking past the building site.
A Health and Safety Executive spokesman said: "Inspectors have attended the site and are making ongoing enquiries in conjunction with the Metropolitan Police to investigate the circumstances of the incident.
"As the investigation is ongoing we are unable to comment further at this time."
