Police are reoffering a £10,000 reward for information that brings the killers of a man from Fazakerley to justice.
Today marks four years since 25-year-old Daniel Keatinge was shot dead.
Officers were called to the scene on Higher Lane in Fazakerley on the evening of 30 January 2009, after they received reports of a shooting.
Daniel was found with gunshot wounds and taken to hospital by paramedics. He was pronounced dead that evening.
Detective Superintendent Dave Brunskill, from the Merseyside Police Major Incident Team, said: "It has now been four years since Mr Keatinge was murdered and I am taking this opportunity appeal once again to the community for their help with the investigation.
"We understand that people are sometimes reluctant to come forward in the aftermath of such a serious crime as this.
"The passing of time may enable people to search their consciences and find the courage to come forward to tell us what they know.
"Four years on, people may have moved from the area or may be in a different situation from then and now feel in a position to talk to the police.
"Anyone with information can speak to us anonymously and in the strictest confidence if need be."
