Detectives investigating a fatal shooting in Merseyside want to speak to three potential witnesses.
Miguel Reynolds, of Manchester, was gunned down in Assissian Crescent, Netherton, on June 7, and later died in hospital.
Police believe an earlier shooting, also with a handgun, in Marie Curie Avenue is linked to the killing of Mr Reynolds, a rapper known as "Migz".
Five people have been been arrested in connection with the murder and officers continue to execute warrants and conduct searches in the area.
Detective Chief Inspector Ian Warlow, of Merseyside Police, said: "While we are keeping an open mind as to the motive for this murder, we are pursuing a number of positive lines of inquiry.
"We do however need information from the community and are continuing to appeal for their assistance.
"We are particularly keen to trace three people who we believe may have information that could assist our investigation.
"Two people were in the area of Henry Hickman Close and Peterborough Drive, when the first non-injury shooting happened on Marie Curie Avenue. We believe they may have seen some or all of the people involved and would be keen to trace them.
"We are also keen to speak with a third person, who was in the area of Magdalen Square towards Peterborough Drive near to the health centre. Again, they may have seen some or all of those involved in this incident.
"I would urge them to come forward and give any information they may have, no matter how small, as it could be vital in progressing our investigation."
He added: "This remains a shocking crime that has taken place in a residential community on a light evening and I know that local residents would agree that the person(s) responsible need to be brought to justice. I would continue to urge anyone with any information to come forward so we can take action."
