A murder inquiry has been launched after a man died almost a week after he was shot while sitting in his car outside his Liverpool home.
Jason Osu, 31, suffered multiple gunshot injuries in the attack on his driveway in Beauclair Drive on the evening of November 19.
The amateur pilot was taken to hospital but died in the early hours of November 26, Merseyside Police said.
A post-mortem examination will be carried out to establish the cause of death.
Merseyside Police's Major Investigation Team is leading the investigation, working alongside the force's dedicated gang crime unit, Matrix.
Detective Superintendent Mike Shaw said: "This was a brutal murder where a man has been targeted outside his home. It happened very close to Queens Drive, one of the city's major roads, at a very busy time and we are hoping that there are people out there who may have seen something."
Detectives are looking for two men who may have been waiting in Beauclair Drive, in Wavertree, for up to 40 minutes before they opened fire on Mr Osu.
It is thought the men, dressed in dark anorak-type jackets and balaclavas, then escaped in a dark-coloured hatchback car, possibly a stolen black Citroen C4, which was found burning nearby in Waldgrave Street shortly after the attack.
Mr Shaw added: "There will be an increased police presence in the area in the days to come, and I would ask anyone with information about the murder to talk to officers or call the incident room."
Anyone with information is asked to contact Merseyside Police on 101 or call Crimestoppers on 0800 555 111.
