Police officers found Andrew lying on Hanover Street, at its junction with Gradwell Street, just before 3.30am.
He had suffered serious head injuries and was taken to the Royal Liverpool University Hospital where he died the following day (Monday, 10 March).
Detective Superintendent Sue Coombs said: "Since Andrew's death his devoted parents, Christine and Andy, have campaigned tirelessly so that they can get justice for their son.
"They have been through a traumatic experience with many questions that remain unanswered. They have lost their son in a tragic and horrendous way, and they are still struggling to come to terms with their loss.
"They will not be able to rest until those responsible are brought to justice.
"Inevitably there are people who know what happened that night and are aware of those responsible for Andrew’s death.
"If you have information that can help with the investigation then we urge you to search your conscience and realise the pain and distress that Andrew's family still feel to this day.
"By coming forward now, you can help bring this investigation to its proper conclusion and help Andrew's family find justice and help bring some peace."
