Detectives from the Metropolitan Police Homicide and Major Crime Command are appealing for the public's help after a father and daughter were murdered at a flat in Deptford.
The bodies of Noel Brown, 69, and his daughter Marie Brown, 41, were found at Mr Brown's flat in New Butt Lane, SE8 in the early hours of Monday, 4 December.
Police had been contacted by a member of Marie's family at 00:30hrs on Monday, 4 December after Marie had failed to return to her home in Southwark having been to check on the welfare of her father. Officers attended Mr Brown's home address at 02:45hrs that morning and forced entry to the property.
The bodies of Noel and Marie were found inside the flat.
Detective Superintendent Paul Monk, who is overseeing the investigation into their murders, said:
"Today, I am asking for the public's help as part of our investigation into the murder of Noel and his daughter Marie.
"We know that Noel was last seen alive and well at his home by a neighbour at about 20:00hrs on Thursday, 30 November. Marie, having grown increasingly anxious about her Dad's wellbeing, went to visit him at about midday on Saturday, 2 December. That is the last sighting of Marie alive.
"Our investigation is fast moving and making progress every day. I want to reassure people that we are doing all we can to find those responsible for the murders of Noel and Marie.
"I am asking the public to help us with any information they may have that could assist our investigation - specifically about two men who visited Noel's flat in the days prior to his death. If that was you, or you know who it was, please get in contact with us.
"At this early stage we are keeping an open mind regarding the motive, however it was clear to the responding officers that there were no signs of forced entry to the property. One of our key lines of enquiry is to establish if the suspects or suspects were known to Noel and if Marie disturbed them."
Officers are carrying out extensive local enquiries around Noel's Deptford home, collecting hours of CCTV and carrying out full forensic searches of the areas in and around his flat.
Detective Superintendent Monk continued: "One of the key strands of our investigation is understanding all we can about Noel's life. He was well known and liked locally. We know that Noel used to go to his local betting shop, Paddy Power, in Deptford High Street and had in fact been there during the day he was last seen alive on 30 November. There has been speculation that his murder was as a result of a large gambling win, however at this time there is no evidence to suggest this was the case.
"I am keen to hear from anyone who saw Noel in the days leading up to his death or saw anyone or anything unusual in or around New Butt Lane, SE8 during that time.
"This is a deeply distressing time for Noel and Marie's family as they come to terms with their loss."
Post mortem examinations at Greenwich Mortuary held on Tuesday 5 and Wednesday 6 December have confirmed that both Noel and Marie died as a result of strangulation.
Specially trained family liaison officers are supporting Noel and Marie's family at this tragic time.
