The leader of the Comancheros outlaw bikie gang is refusing to co-operate with police after surviving another attempt on his life, a shooting that also killed his son.

Vincenzo Focarelli is in hospital with gunshot wounds and is refusing to tell police who shot him and killed his 22-year-old son, Giovanni, on Sunday night at Dry Creek, in Adelaide's northwest.

It was the fourth attempt on Vincenzo Focarelli's life.

He was shot in the leg in December and was also the target of a failed bomb attack by two men linked to the Hells Angels who both died when the device exploded early.

He reportedly taunted his rivals on Facebook a day after surviving the third attempt on his life - including boasting that he had nine lives.

He can be seen dancing in a YouTube clip that appears to be promoting life in the Comancheros in Adelaide.

Detective Superintendent Grant Moyle says police will do everything they can to prevent retaliation. "I would suggest it was a very planned, targeted attempt on his life.

"It is a concern to us that retribution might take place, but we will do what we can to talk sense into these people.

"He has declined to provide us any information that might assist us in identifying the offender.

"That is a difficulty we face in these particular cases."

South Australian Police Minister Jennifer Rankine says police are doing their best to deal with the scourge of outlaw gangs and SA has very tough anti-bikie laws.

"Hundreds of them have been arrested and charged. Hundreds of their associates have been arrested and charged," she told ABC Radio.

"The frustration is these people have absolutely no regard for the law or, it would appear, for their safety or the safety of the community."

Police are doorknocking an area near Flame Ave in Dry Creek where they believe the Focarellis were shot.

Vince Focarelli, who is believed to have been wounded up to four times, apparently bundled his son into a car and drove it towards the city, waving a police car down in suburban Prospect.

Giovanni was dead by the time an ambulance crew arrived.

The 22-year-old had also been attacked before and had refused to co-operate with police investigating his attempted murder.
