A CHIEF suspect has been identified in a horrific city murder where the killer escaped on a push bike.
Gardai have made a fresh appeal for information about the murder of 21-year-old north inner city man Gavin McCarthy, who was shot dead four years ago yesterday.
Sources say officers believe that people in his locality have key information about the shocking feud murder on Lower Sheriff Street.
The Herald can reveal that a chief suspect has been identified in the case.
The 21-year-old suspect is serving a long jail term after he was caught with a loaded firearm in a stolen car in relation to a separate incident.
A garda spokesperson said: "Gavin was in the company of his brother and others standing outside a fast food outlet on Lower Sheriff Street.
"After leaving the Chinese takeaway, he was approached by a male on a pedal cycle and shot dead.
"Now, four years on from Gavin's death, gardai are hopeful that people's circumstances may have changed and anyone with information is urged to contact the Incident Room at Store Street Garda Station on 01-6668089 or contact the Garda Confidential Line 1800 666 111.
Mr McCarthy's heartbroken brother Daniel witnessed the murder from a car nearby and even chased the gunman on foot. The gunman managed to escape but Daniel saw him drop his firearm and later helped gardai recover the Glock.
Tragic Daniel was so traumatised by watching his older brother being murdered in front of him that he later took his own life.
Mr McCarthy was shot several times in the face in the attack that was connected to the bitter north inner city feud which centres around jailed paedophile gang boss Christy Griffin.
The chief suspect was one of three people arrested in relation to the McCarthy murder but there have been no charges in the case.
