Conor Browne (28) died in hospital two days after being stabbed outside a pub in Castlederg’s Main Street in the early hours of Saturday morning.
The ‘Vigil of Remembrance’ will take place in The Diamond area of the town at 8pm on this evening, Wednesday, September 6.
Organisers Darkness Into Light have said Conor’s killing has left a “dark cloud” hanging over the community.
“Our town of Castlederg was sent into a sense of shock, disbelief, anger and sorrow over the last few days,” they said.
“Conor was a much loved father, son, brother, uncle, cousin and a brilliant friend to so many people. His death has affected everyone who had the pleasure of knowing this great fella and it has affected people whom never had the privilege of meeting him.
“We as a community want to show our support and solidarity to Conor’s immediate family and to the Browne and Collins family circle.
“We want to let the people know that all the good work that has been done in our town is not going to be undone by this vile act.
“We invite everyone near and far to join us to remember this very special young man whom has had his life cut short.
“We ask you to keep Conor’s family and friends in your prayers.”
