A motorist was killed in a drive-by shooting as he waited at traffic lights, police said.
The 23-year-old man was blasted with bullets as he sat at the wheel of his red Ford Transit Van in Crosby, Merseyside, at around 11.20pm on Saturday.
The victim, who has not been named, died at the scene but his girlfriend, who was sat in the passenger seat, escaped with minor injuries.
Merseyside Police said the motive remains unclear but added that the victim was already known to officers and the murder is being treated as a targeted shooting.
Detective Chief Inspector Tony Doherty, who is leading the inquiry, said: "This is somebody's son who was shot dead in the street.
"He didn't deserve to die like that. The bullets could have struck anybody and we will not tolerate the criminal use of guns.
"The victim was known to us and is from the Netherley area of Liverpool. He was passing through Crosby with his girlfriend and, as well as the forensic examinations and patrols in that area, we will also be increasing patrols and conducting investigations in Netherley."
Mr Doherty said the van was about two or three cars back in the queue at traffic lights on Crosby Road North when a silver Audi car pulled up alongside and the gunman opened fire.
Police are still trying to identify how many shots were fired but early witness statements suggest a number of rounds were directed from the Audi to the van before a brief pause as the Audi was reversed followed by several more gunshots.
Afterwards, the Audi was driven off and abandoned on Fairfield Close, Crosby, and set alight.
