Murder squad detectives are continuing to question a 31-year-old man over a fatal hit-and-run rampage as nine victims remain in hospital.
A church service will be held later in Ely, Cardiff, in support of the victims and their families, while candles and flowers continue to be left at the crash site outside the fire station on Cowbridge Road West, where 32-year-old mother-of-three Karina Menzies was killed.
Two of the injured adults were in a critical condition and five children were also receiving treatment after the driver of a white van brought bloodshed to the streets of the Welsh capital on Friday afternoon.
South Wales Police have been granted a further 36 hours to detain and question the arrested man.
Detective Superintendent Paul Hurley said the suspect carried a weapon and left his Iveco van to physically assault people. He said police were looking to identify and recover the weapon, which was believed to be a crook lock.
There were also unconfirmed reports police were investigating if the driver was involved in a domestic incident before the rampage. Police said a key part of the inquiry is focused on establishing who owns the white van.
More than 70 officers are working on the investigation, studying CCTV footage and taking witness statements to help build a picture of what happened.
Mr Hurley urged witnesses to get in touch and asked for information about a black Renault Clio seen driving on the wrong side of the road of Western Avenue, not far from Cowbridge Road West.
The first incident to be reported was in Crossways Road in Ely at 3.30pm. It was soon followed by other reports of hit-and-run collisions in several locations in the west of the city, including Grand Avenue, Cowbridge Road West and the Leckwith Retail Park.
