As many as ten firearms have been removed from the house where a couple was found dead in Melbourne's south-east.

The guns, mostly in cases and long-armed, were taken away by police about 2.15pm on Thursday.

Police also removed two computer hard drives from the house on Omama Road in Murrumbeena, not far from Chadstone shopping centre, and towed a four-wheel drive vehicle believed to be owned by the couple's son from the property.

On Thursday afternoon, a police spokeswoman said the firearms were registered to Mr Adamson and were not part of the homicide investigation.

Colleagues found Cheryl Adamson, 60, and her husband Robert, 65, dead at their home on Wednesday afternoon after Ms Adamson failed to turn up to work.

The killer remains at large, as police comb the area for clues and search for a motive.

The mid-1990s white Nissan Patrol was taken away by forensic police just after midday on Thursday.

The car was parked at the Adamson property in a driveway.

A Victoria Police spokeswoman said the vehicle would be forensically examined and the investigation was ongoing.

It is understood that Ms Adamson was a senior teacher librarian at the Grimwade House junior campus of Melbourne Grammar School, and her husband was an accountant.

Detectives were called to the house just after 12.30pm and began searching the area for a weapon they suspect may have been used to kill the couple on Tuesday night.

"It is quite a brutal scene," Detective Senior Sergeant Stephen McIntyre, of the homicide squad, said.

He said police were awaiting the outcome of an autopsy, and were not ruling anything out.

"They've both been assaulted and it would appear that a weapon was used, but until we've done a post-mortem we won't know what that weapon was been," he said.

There were no obvious signs of forced entry to the home.

Tearful neighbours watched in disbelief as police combed Boyd Park, near the couple's home, in an effort to try and find the weapon.

Ted Fentiman, who has lived next door to the Adamsons for about 40 years, said he was "at a loss to imagine who would do this thing".

"I know them extremely well and I couldn't imagine who could have perpetrated this but I guess that we'll find out eventually," he said.

"It all comes as a bit of a shock."

He said the couple's two children had a close relationship with their parents and their son was due to marry later in the year.

A distressed friend, who did not want to be named, said those who knew them were in shock.

"They were a lovely couple," she said.

"We feel desperately for the children.

"This is a close community around here."

The couple's adult son, who lived with them, is helping police with their inquiries. He is not being treated as a suspect, Detective McIntyre said.

Melbourne Grammar School headmaster Roy Kelley said Ms Adamson was a highly regarded and dearly loved staff member.

‘‘We extend our deepest sympathy to Cheryl’s family at this very difficult time. Cheryl was a highly regarded member of the Grimwade House team, loved and respected by her students, their parents and her colleagues.

‘‘Her loss will be deeply felt.’’
