Thanks @Oliver Schick. If there are any witnesses, there is an appeal to come forward.
Marta will be greatly missed. She was on her way to work as a consultant pediatrician. She started cycling to get to work during the pandemic. We often waved at each other in the morning as our routes crossed as well.
There will be a Requiem Mass on Saturday morning at Old St Pancras. https://stpancrasoldchurch.posp.co.uk/marta-krawiec-rip/
