THE silver BMW involved in the execution-style murder of a man at a Brisbane shopping centre was in the carpark for up to 30 minutes, police have revealed.

The victim, a 22-year-old Eight Mile Plains man, arrived at the Warrigal Rd shopping centre just before 6.40pm yesterday to meet friends for dinner.

Police believe the BMW a 1991 model two-door coupe - arrived about 10 minutes later.

At some point, the victim walked out to the car, where he was shot in the head.

"Timing in relation to this crime is very important," Detective Superintendent Mick Niland said.

"It was at approximately 6.50pm a silver BMW coupe was seen to enter that shopping centre.

"We believe that it may be linked to this crime and it was seen to arrive at that time and then it departed at approximately 7.20pm."

Police received a Triple-0 call at 7.27pm from a person reporting a shooting in the carpark.

'I saw the ambulance come'



Earlier, the Courier-Mail reported that the owner of the sushi restaurant where the victim was shot had told how he went outside to take a phone call just minutes before being gunned down.

The man was shot in the head about 7.15pm last night and died around 1.50am this morning in Princess Alexandra Hospital.

Sushi Train owner Naoki Yamamoto told The Courier-Mail the shooting victim had not been eating, but his two male friends were.

"He took a phone call and went outside and that seems to be when it happened," Mr Yamamoto said.

"I didn't see it happen. I only saw the ambulance come."

Second shooting in 24 hours

The shooting came less than 24 hours after 56-year-old father of two John Lazzaro was gunned down in his loungeroom at nearby Rochedale South on Wednesday night.

Detective Superintendent Michael Niland says there are no apparent links at this stage.

"We'll look at all angles but at this stage there are no connections," he told ABC Radio.

'The kind of thing that would happen in America'

Stunned shoppers and business owners came to look at the crime scene this morning, expressing shock and dismay.

Nearby neighbour Kerrin Miller, whose home backs in to the carpark where the young man was shot, said it was terrifying.

"I was out the back having a cigarette when I saw all the police cars and thought it had to do with the shooting at Rochedale," he said.

"It's awful. The kind of thing that would happen in America, not Australia."

Bakery owner Jessica told ABC Radio such crimes weren't common in the area.

"We are all pretty shocked and amazed this morning," she said.

Police were interviewing a number of witnesses and are not allowing people to take their vehicles from the carpark until crime scene investigations are completed.

Detectives from the homicide squad and state crime operation command, as well as Mount Gravatt criminal investigation branch, are investigating, with a major incident room established at the Mount Gravatt Police Complex.

Police would like to hear from anyone who may have witnessed any suspicious behaviour in the area around the time.
