Detectives investigating the brutal murder of a City banker who was beaten to death in her luxury riverside flat believe the main suspect may have fled the country.
Marianne Kilonzi, 43, was discovered by officers with fatal head injuries at her home in Woolwich, south-east London, on Friday afternoon.
A neighbor had heard 'blood-curdling screams' earlier that day from the flat in Argyll Road, where house prices average £442,000.
Her suspected killer is believed to be known to her and one of the lines of inquiry from Scotland Yard's murder detectives is that he may have fled the country.
A post-mortem examination on Saturday revealed Ms Kilonzi died of blunt force trauma to the head. She has been formally identified.
Neighbors reportedly raised concerns with investigating police officers after hearing a loud disturbance coming from her apartment.
Residents of the exclusive Royal Arsenal Riverside development were questioned early on Monday morning about the 'noisy nuisance' in her first floor apartment.
Ms Kilonzi's lifeless body was found on Friday afternoon after police officers entered her property amid concerns for her safety.

Neighbor Michael Buckingham, 82, told MailOnline: 'The police came round and asked me some questions.
'An officer asked me if I had heard anything from her flat between 3am and 4am on Monday morning. It appears that there was a noisy disturbance at the time.
“Unfortunately I couldn't help them because I didn't hear anything.”
Police forensic officers spent the weekend searching the flat, which overlooked an internal lagoon with fountains.
A cleaner said: 'The police have searched the whole flat. They also searched the garbage bins.”
Mr Buckingham added that he believed detectives had already identified a suspect.
The retired company director said: 'The police know who they are looking for. They don't look for anyone else. It's just a matter of finding him.'
Chief Inspector Suzanne Soren said: “This is a tragic crime and our thoughts at this incredibly difficult time are with Marianne's loved ones and colleagues.

'We are in contact with her family, who are supported by specialist colleagues.
'I know this is a worrying time for the wider community and I would like to reassure the public that whilst we are in the early stages of this investigation, we believe the suspect was known to Marianne and that there is no greater risk to the public consists.
“This is a rapid investigation and I would appeal to anyone with information to come forward.”
A spokesperson for the Metropolitan Police confirmed to MailOnline that one line of inquiry being investigated as part of the investigation is that the suspect has fled the country.
Ms. Kilonzi worked at Citi for more than 18 years, according to her LinkedIn profile, and previously led a corporate fundraiser for cancer research.
A Citi spokesperson told MailOnline: 'We are deeply saddened by the tragic loss of our colleague. Our thoughts are with Marianne's family and friends at this difficult time.'
Ms Kilonzi's death comes just days after a fatal stabbing in the same area where a 14-year-old boy was killed.
Two teenagers aged 15 and 16, who cannot be named for legal reasons, appeared in court last week charged with the murder of Kelyan Bokassa.
Kelyan was attacked with two machetes and stabbed 27 times during the horror incident on bus 472 in Woolwich Church Street on January 7.
The two incidents are not believed to be related.
