A former NSW detective has been charged with the murder of a missing Sydney university student and police also want to speak to disgraced detective Roger Rogerson over the disappearance.
Glen McNamara, 55, who was stationed at Kings Cross during the late '80s, was charged with the murder of Jamie Gao early on Monday.
Police are now searching for Mr Rogerson, an associate of Mr McNarama, to question him in relation to Mr Gao, 20.

NSW detectives are flying to Queensland on Monday to talk to Mr Rogerson.
Mr Gao, from Hurstville, has been missing for six days after getting into a white car with two men in Padstow about 1.40pm on Tuesday.
Police suspect he has got ''in over his head'' and was kidnapped and killed after arranging a ''secretive'' meeting with an unknown party.

Mr Gao was last seen getting into the car on Arab Road in Padstow shortly after speaking to two men, both described as being of Asian appearance. He was carrying a bag.
Mr Gao's own car, a white Nissan Silvia sedan, was found abandoned near where he was last seen. His phone, keys and wallet were nearby.
On Sunday, the head of the Robbery and Serious Crime Squad, Detective Superintendent Luke Moore, said the circumstances of Mr Gao's disappearance suggested foul play.
Hours later, Mr McNamara was pulled over during a traffic stop at Kyeemagh in Sydney's south and he was questioned overnight before being charged with murder and drug offences.
Mr McNamara is a former investigator with the National Crime Authority and the NSW Police; he was a detective stationed in Kings Cross and Sydney's south. He gave evidence to the NSW Police royal commission about alleged police protection of paedophiles.
Mr Rogerson, 73, was a decorated senior police officer until he shot and killed drug dealer Warren Lanfranchi in 1981.
He was later accused of supplying drugs, assault, bribery and conspiring to murder, but was never convicted.
He was twice convicted for lying in court and served two separate jail terms.
Mr McNamara's Cronulla home has been searched by police and a blue Ford Falcon XR6 was seized from his premises.
Mr Rogerson's Padstow Heights home was also searched and a car, a silver Ford Falcon, was taken away.
Police also searched a storage unit at Caringbah where a boat was taken away for forensic testing.
A third car, a silver Ford Falcon, was found at another location in Cronulla. It is this car detectives believe Mr Gao got into at Arab Road last Tuesday.
Superintendent Moore said the investigations would continue.
“Our inquiries to date have led us to conclude that Mr Gao has been murdered,” Superintendent Moore said.
“While we have charged a man with murder, this investigation will continue and we may make further arrests.
“We still don’t know where Mr Gao’s body is and are strongly encouraging anyone who can help us locate his remains to contact police.”
Mr McNamara appeared in court on Monday afternoon charged with and with a major drugs charge.
Supported by his family, the 55-year-old did not apply for bail before Kogarah Local court and it was formally refused.
Mr McNamara returns to court in July.
