Family members have joined police in their appeal for witnesses after three people were killed in a crash at Menangle, in Sydney's south-west, yesterday.
About 11.25am (Tuesday 24 January 2012), emergency services were called to the northbound lanes of the Hume Highway following a collision between a B-double truck and Ford Mondeo.
The three occupants of the Ford died at the scene.
Police can confirm the identity of the driver as 59-year-old Calvyn Logan from Forster and the two passengers as his parents, 81-year-old Donald Logan and 81-year-old Patricia Logan, also from Forster.
The 33-year-old male truck driver sustained minor injuries and was taken to Campbelltown Hospital for treatment.
He has also undergone mandatory blood and urine testing.
He was later taken to Campbelltown Police Station where he assisted police with inquiries.
Officers attached to Camden Local Area Command, along with the Metropolitan Crash Investigation Unit, are investigating the circumstances surrounding the crash.
Robert and Gary Logan, Calvyn Logan's sons, have today (Wednesday 25 January 2012) joined police to appeal for anyone who may have been driving on the Hume Highway at the time of the collision to come forward.
Traffic and Highway Patrol Operations Commander, Acting Assistant Commissioner Stuart Smith, said investigators have already spoken with a number of witnesses.
"A number of motorists stopped at the time of the collision to render assistance and many of them provided detailed statements to police," said Acting Assistant Commissioner Smith.
"We are aware there a number of motorists that didn't stop, for whatever reasons, but we would still like to speak with them.
The 18-year-old female learner driver of a vehicle sought by police has now been interviewed and inquiries are continuing.
Her father, who was supervising her at the time, has also spoken with police.
"Any witnesses who haven't spoken to police are urged to contact Metropolitan Crash Investigation or Crime Stoppers on 1800 333 000," Acting Assistant Commissioner Smith said.
