Mr Chadwick was described as a brilliant father to Ruby
Police hunting the killers of a young father shot dead in an apparent case of mistaken identity have released fresh images of a car used in the murder.
Adam Chadwick, 20, had been visiting his sister Gemma's house on Clifton Mount, Harehills, on 24 June when three masked men and a woman burst in.
He was shot in the head and died in hospital two days later.
New images show a blue Ford Focus, which was used by the gang, at a petrol station in the city.
Police recovered the car, registration number YH54 SBV, from the Chapeltown area on 25 June. It had been stolen from the Little London area on 11 June.
Four days before the shooting it was caught on CCTV on the forecourt of the BP garage on Roundhay Road, Chapeltown, where its rear offside tyre was filled with air.
When the car was recovered, it was found that tyre had been replaced with the vehicle's spare spacesaver wheel.

Det Supt Steve Payne said: "There was a number of vehicles on the garage forecourt when the Focus pulled in and the tyre was filled with air, so it is very likely that someone may have seen the driver or passenger filling the tyre.
"This tyre was probably punctured before it was filled up on 20 June which would explain why the spacesaver wheel was on the car when it was recovered.
"It is possible that someone may have witnessed the driver or passenger changing the wheel by the roadside between 20 June and 24 June, when Adam was shot."
Mr Payne had earlier said Mr Chadwick, who had a three-year-old daughter named Ruby, may have been the victim of mistaken identity.
Officers also want to trace the woman who was with the men on the night of the shooting. Police said she had been knocking at doors earlier in the evening asking for "Michelle".
Mr Payne added: "We are convinced the answer to who killed Adam lies within the local community, and we would encourage anyone with information to come forward."
