Paulius Petrasiunas died after being attacked with a machete outside a block of flats in Chevril Rise, Heath Town.
The attack happened just before 5.20pm on Monday.
Mr Petrasiunas, originally from Lithuania, lived in Heath Town and had a one-year-old son called Kingsley-Clifford.
Now a fundraising page has been set up to help raise funds to pay for his funeral – and towards his son's upbringing – with a target of £5,000.
A statement on the Crowdfunding website reads: "We are raising money for our dear kind, loving and humble friend Paulius also known as Polo who has been a loving son, great boyfriend, caring friend and mainly a new father who has been tragically murdered in broad daylight.
"Money raised will support and help to fund costs of funeral and for Paulius' son's upbringing in anyway possible
"Our hearts is with his family which is also our family too. Everyone who knew Paul is devastated and can't believe that his has happened to our humble and quiet friend any help will be very helpful and welcome.
"You will always be with us and in our hearts."
