Murder has shocked entire city
Mr Durkan appealed for anyone with information to contact the PSNI.
“This morning a family is coming to terms with the death of a son in the most horrific of circumstances. The loss of a young man in any circumstances is absolutely tragic but to have had someone with their whole life in front of them murdered like this will be particularly devastating for his family and his community.
“My thoughts and prayers, and those of my party, are with the young man’s family and friends at this difficult time. I have no doubt that the community here will rally around them and provide every support that they need.
“I would urge anyone with any information about this crime or who may have heard a disturbance in the Milldale Crescent area last night to come forward to the police as soon as possible.”
