Also any work crews, or even people driving by. I've known cases where they tracked down every car whose tag they could read on the dash cam as they went by an incident.
Then you need to do a proper interview. Not a stand there with a notebook, but sit down and recorded. That takes time to arrange and make happen with people's work schedules and what else investigators must do.
It can easily go into several days.
This can be made worse if there are reluctant witnesses. In a case like this you see the community narrative and late protests, some violent, insisting he was unarmed. A witness who may have seen him armed, or even knew he and a gun earlier in the day, might be very reluctant to come forward with an account counter to the prevailing narrative in their community and it can often take several days to get such a witness to forward.
Yes, it can easily take many days to do right. For a good example go read the DOJ report on Ferguson and see how long it took and how much trouble it was to locate all the witnesses and get statements. And also note how many of them admitted to or were found to have changed stories based on what they heard in the media.
