KEY clues to help solve the MH370 mystery could be inside a suitcase in an Ellenbrook home.

Perth woman Sheryl Keen, the chairwoman of Air Crash Support Group Australia, has had about 20 items stored in a suitcase at her home since September, which she’s confident are personal effects belonging to passengers aboard the doomed Malaysia Airlines jet.

The items, mainly shoes and handbags, were handed to Ms Keen by amateur MH370 investigator Blaine Gibson, a US lawyer who has been scouring the islands off east Africa for debris belonging to the mystery plane. Unfortunately, none of the battered items contain anything that identifies their owners.

The Malaysian Government refused to take the debris, claiming they were not linked to MH370, Ms Keen said.

To date, seven pieces of debris recovered from islands and the east African coast have been confirmed as part of the missing plane which vanished on March 8, 2014, with JU239 passengers and crew on board, including Perth man Paul Weeks.

Ms Keen said she contacted the Australian Federal Police, which has agreed to catalogue and forensically examine the items in her possession, all of which were found along a 13km stretch on Riake Beach in Madagascar.

She said the items in her suitcase were only a small sample of the personal effects found washed ashore in the area, much of which still remains in Madagascar.

“How many beaches have you been to where 100 handbags wash up and not just 100 handbags, but 100 handbags all in the same condition? It’s not like some were there 10 years and some were there 10 months, they’d all deteriorated to the same level,” she said.

“The fact the items we’ve recovered are all cabin-type debris, we’re not seeing suitcases or things that would be in the (cargo) hold ... it tells me that part of the aircraft (cabin) broke apart.”

Among the items is a single brown slipper, which Ms Keen believes may belong to an Asian woman seen wearing similar footwear with white socks on CCTV footage before she boarded MH370.

The unknown woman has been dubbed “Cinderella”.

“Without hope, what have you got?” she said. “We want to find out what happened to the aircraft and bring answers to the families. This is a travesty, we can’t allow this to go on with no answers because what will stop it from happening again and again and again.

“The families want people to know it’s bigger than just them. It affects everyone that flies. Although it’s really sad for them, they want answers for us as much as for their own circumstances.”

The AFP confirmed it had been contacted by ASGA regarding items in the group’s possession and it was seeking advice from the Joint Agency Co-ordination Centre. The JACC, which is co-ordinating the search and recovery mission, said the AFP’s request was under consideration.

Ms Keen, who lost her agriculture pilot husband in a 2009 plane crash, said the Malaysian Government, which had responsibility for returning any personal effects to next of kin, was dragging its feet and had only just sent officials to travel to Madagascar to collect pieces of debris.

Seven relatives of MH370 victims are in Madagascar to search for debris and urge locals to keep a lookout for further items from the missing Boeing 777.

Aviation expert Geoffrey Thomas said every avenue should be examined in a bid to solve this extraordinary mystery. He said Malaysia’s lack of interest in potential MH370 debris was “deeply troubling” when the country should be supporting and funding such efforts.

“Some of the stuff they have been finding has been incredibly important in confirming we are looking in the right general area,” he said.

Unlike physical hardware of the plane, personal effects were more difficult to identify unless relatives came forward, Mr Thomas said.

“It’s the most tragic jigsaw puzzle and every single piece is important ... history has shown that the smallest, most inconsequential piece of debris can lead to the discovery of what went wrong.”

Search vessel MV Fugro Equator left Fremantle this week to conduct a final sweep of deep-sea ravines. When the 120,000sqkm search zone is fully combed early next year, the search will be suspended without any new credible evidence.
