COPS are probing five clues in the mystery of missing Gaynor Lord whose belongings were discovered in "various locations" - as the search for her enters its fifth day.
Police divers, fire crews and the coastguard are scouring the River Wensum in Norwich with sonar equipment after Gaynor, 55, went missing.
Norwich Constabulary has also used drones and foot searches in the hunt for the missing mum.
Here are five clues which the force said it is now investigating in connection with Gaynor's disappearance.
1. Coat in water
Cops found Gaynor's olive-coloured coat floating in the River Wensum late on Friday evening.

"While we have a number of inquiries ongoing, given where her clothing was found and other items, there is a real possibility she has entered the water."
2. Clothes found
Gaynor's clothes, rings and mobile phone were found on Friday evening in Norwich’s Wensum Park.
Her white work shirt, yellow tank top, and jewellery were found spread out at different sites across the city centre park.
Cops now believe she went missing at least partially unclothed.

3. Left work early
Gaynor left her job at the Jarrold's department store early on Friday afternoon - and didn't take her normal route home.
Supt Hornigold said: "We haven’t been able to establish why she left early.
"Her disappearance is out of character so we are naturally concerned for her welfare."
4. Last sighting
The mum was last seen walking along London Street in Norwich at 2.45pm.
Gaynor, who has blonde shoulder-length hair in a bob, is described as white and 5ft 6 inches tall.
The sighting has helped cops piece together a timeline of Gaynor's last movements.
5. ID in handbag
Norwich Constabulary declared Gaynor missing after they found her ID inside a handbag - and learned she'd failed to return home from work that evening.
Supt Hornigold said: "We’ve been liaising with the National Crime Agency who have given advice around specialist underwater dive teams.
"We’re seeking assistance from forces with this capability.

"This is clearly a distressing time for her family. We have specialist officers supporting them and continue to keep them updated of our ongoing work."
