The bodies of two small children and their father have been found in a submerged car at Port Lincoln after a search by South Australian police divers.The white station wagon was spotted driving off the end of Brennan's Wharf about 6:00am Monday, and sank in up to 30 metres of water.
Police said the car was travelling up to 80 kilometres per hour, and witnesses told police it seemed the vehicle had been deliberately driven off the wharf.
Divers from SA Police's Water Operations Section flew to Port Lincoln from Adelaide for an underwater search, and police said the bodies of the man and children were found just before 12:30pm.
Their bodies were removed from the car before it was pulled to the surface.
Superintendent Paul Yeomans said they had now been identified, and described the situation as a "heartbreaking incident".
"It's a tragic case where you've got, we believe, the father and two young children in the vehicle," he said.
"No doubt, this will affect a lot of people living in Port Lincoln.
"We're not treating it as an accidental driving-off-the-wharf.
"Even though at this stage I'm not prepared to release the details of the deceased, they have been identified."
Police said the local family involved had been informed.
"There was a rifle that was retrieved as part of the retrieval process," Superintendent Yeomans said.
"Whether that's involved in the incident I don't know. That'll be subject to the investigation."
Superintendent Yeomans would not say if there were signs of injury on the bodies.
