Police investigating the disappearance of teenager Alice Gross are searching a former west London home of suspect Arnis Zalkalns.
Scotland Yard said forensic officers were searching the house in Boston Manor Road, in Hanwell.
The owner of the house, Radoslav Andric, said he last saw Zalkalns at the rental property two days before Alice went missing on August 28.
Alice was last seen on August 28 walking across a bridge over the canal Mr Andric said the Latvian builder moved out more than a year ago, but had returned to see friends.
Police have recovered the suspect's red Trek bicycle from the property.
Zalkalns was seen on CCTV footage cycling along a path by the Grand Union Canal 15 minutes after the last sighting of Alice.
Alice went missing while walking near the Grand Union Canal Detectives believe he is likely to have seen the 14-year-old as they were both going north along the canal towpath.
The 41-year-old went missing a week after Alice disappeared.
Zalkalns was jailed in his native country in the late 1990s for murdering his wife and burying her in a forest following a dispute about her sexuality.
Officers remove a bicycle from the house in Boston Manor Road Sky's Senior News Correspondent David Bowden said Zalkalns claimed at his trial in 1998 that he feared for the safety of their small child.
"He served seven or eight years - there is some discrepancy about that - and he came here in 2007," Bowden said.
It has also emerged Zalkalns was arrested in London on suspicion of indecent assault on a 14-year-old girl in 2009, but was never charged.
Police have formally named Arnis Zalkalns as a suspect Forensic police have also searched Zalkalns' semi-detached house in Ealing where armed officers have been seen standing guard.
Zalkalns has not accessed his bank account or used his mobile phone since September 3, nor has he returned home to his partner and young child.
He is described as white, 5'10", of stocky build and with dark brown hair that he normally wears tied in a pony tail.
Police search the garden of Zalkalns' semi-detached house in Ealing Zalkalns left his passport at home when he went missing two weeks ago.
Police said it was possible that someone is helping him by providing him with money or somewhere to stay, and warned he "clearly poses a risk to the public".
A reward of £20,000 is being offered to anyone who has information that helps detectives find Alice.
