Forensics teams are today scouring a property in Fulham as police seek to piece together the mystery of the murder of Brook Green man William John Saunderson-Smith.
Detectives believe the home, in Sedlescombe Road, Fulham, may have been one of several owned by 'reclusive' property developer Mr Saunderson-Smith, 58, who died after being hit on the head at his Dewhurst Road residence last week.
The search comes after a large quantity of cash was seized from another home in north-west London.
Police continue to be baffled by the case and are trying to paint a picture of the 'complex' victim's life. They are struggling to track down next of kin and look set to extend their appeal to Northampton and Bedfordshire, as they believe Mr Saunderson-Smith has connections there.
DCI Tim Duffield, leading the investigation, said: "Our enquiries have established that Mr Saunderson-Smith may have had a large number of business associates, spanning London and beyond. We understand that he and his family originated from the Northampton / Bedfordshire area and that on occasions he would travel there to spend time with a distant relative.
"It has become apparent from our enquiries that Mr Saunderson-Smith had been living a complex and reclusive life for some time, and as such I am keen to speak to anyone who knew him and may assist us in building a picture about his life."
Mr Saunderson-Smith is believed to have died some time between 7pm last Thursday (20) and at some point the following morning. He was discovered on Friday afternoon by someone believed to be one of his employees.
He was identified after a post-mortem examination in Fulham on Sunday. No arrests have been made, no weapon has been found and investigations continue to be 'open-ended' as police struggle to piece together the circumstances of killing.
Mr Saunderson-Smith lived alone in the three-storey home in what is an upmarket area of W14. Neighbours approached by the Chronicle said they didn't know anything about the man and were even unsure whether or not the house had been empty as building materials had filled the front patio for several months.
One said she thought the home had previously been a student house because of loud parties but that it had been unoccupied for several weeks.
Planning records on the house from last year showed the council were preparing to take enforcement action against the owner for turning the house into flats without permission, but police say the man lived alone and that the property remained a house.
Mr Saunderson-Smith was also the subject of leasehold valuation tribunal in 2008 with regard to a property in Wimbledon.
DCI Duffield said witnesses were needed to help piece together the crime. "I'm eager to speak to anyone who was in or near Dewhurst Road during that period. It's quite possible a person or a vehicle was seen hanging around the area or leaving in a hurry, which at the time may have seemed insignificant. If you're in any doubt, please contact the incident room. All calls will be treated in the strictest confidence."
The killing is the second murder in area this year. In May, Randy Osei-Boateng, 23 , was shot in the chest in broad daylight in Lakeside Road.
