Police investigating the murder of Graham Williamson yesterday spoke with over 50 people as part of their enquiries.
The 26-year-old was gunned down from behind on Caithness Street in Blantyre on August 17.
Members of the public and motorists were spoken to by investigators on Monday in an effort to glean more information about the murder.
Graham leaves behind his partner Amanda and their two-year-old son.
Police believe that a dark blue Skoda car seen driving off at speed after the shooting could be linked to the incident.
Detective Superintendent Kevin Jamieson, Major Investigation Teams, previously said that the response from the public has been 'encouraging'.
He added: "People are really shocked about what has happened.
"From our enquires, we believe now that a dark blue Skoda car - a newer model, possibly an estate car - was in the area at the time of the shooting and it was seen to drive off at speed after the attack in the direction of Blantyre Main Street, possibly towards Douglas St and maybe the expressway or other roads nearby.
"Whether linked to the incident or not, we are still interested in speaking to its occupants or indeed anyone who may have seen the car, or who may be has dash-cam footage of it in Caithness Street, either before or afterwards, or in streets nearby.
"We have set up a dedicated website that gives members of the public access to a form to send information direct to the major incident teams based at the Scottish Crime Campus. This can be accessed here. "
A Police Scotland statement released this morning said: "Yesterday afternoon/evening, a week on from the murder of 26-year-old Graham Williamson in Caithness Street, Blantyre, officers were back in the street speaking to pedestrians and motorists in an effort to glean more information about his murder.
"Officers spoke to over 50 people and the information provided has proved helpful to the investigation."
Detective Superintendent Kevin Jamieson commented: "Last night's operation was helpful in terms of information passed to officers. People sometimes don't realise they have information that can help investigations, so it is always good to have officers return to the scene and speak to people who live, work or socialise in the area and to ask them about what happened and how they can help.
"As I have said before, people are shocked and very upset by what has happened and we have been really encouraged by the response from the public so far."
Anyone with information is asked to contact police on 101, quoting reference number 2517 of 17 August 2020 or to remain anonymous, contact the independent charity Crimestoppers on 0800 555 111.
