The majority of Myer's Park was reopened to the public today and one of the three Asian people police were hoping to speak to made contact with investigators. The man will be interviewed in the company of an interpreter tomorrow.
Mr Harris was known to attend the Urban Vineyard church, and outreach officer Cameron Webster said he had arrived early on Wednesday to help dish out lunch for the homeless.
"He came in early, I had talked to him on Sunday and I invited him to come along early and give us a hand, so he came along and was helpful.''
He described Mr Harris as "a very talkative sort of fella''.
Mr Webster said the violent death of a second homeless person in just over a month would "rock the [homeless] community''.
"That sort of stuff it's not much fun for all these guys,'' he said. "It's amazing how they rally around when stuff like that happens.
"To live on the streets there's always the worry of stuff like this but I think that heightens that worry. I can't imagine how they would be feeling when this happens, within two months two guys have been killed.''
Homeless man Edwin Linder, 42, was also killed in a CBD attack, in Mills Lane on August 3.
