“Sadly, the body has been identified as missing woman Janet,” police said in a statement.

The location is about an hour’s walk from where Knight was last seen on CCTV, walking along Hoffmans Rd towards Keilor Rd in Niddrie about 7.38am on Sunday.

Police are not treating her death as suspicious.

Knight had left home without her phone, wallet or Fitbit, which her family said was out of character.

Her disappearance sparked a large-scale search, with police and family concerned for her welfare due to her dementia diagnosis and the cold, wet weather.

Victoria Police Inspector Bonnie Heazlewood previously said Knight was fit, regularly went for walks and knew the local area well.

Her daughter, Nicole, said Knight had been diagnosed with a rare and aggressive form of dementia that affected her ability to communicate, although her memory was not as severely impacted.

“We would like to extend our appreciation to the media for their assistance during the search and our thoughts are with the family during this difficult time,” police said.
