Police officers hunting the killer of a senior banking executive who was found dead in her south-east London home are investigating whether the suspect may have fled abroad.
Marianne Kilonzi was found fatally beaten in her flat in Woolwich on Friday evening, the Met Police said.
A post-mortem examination gave the cause of death as blunt-force trauma and a head injury.
The 43-year-old, who was a vice president at the major financial institution Citibank, is believed to have known her attacker, the force said, adding that whether the suspect had fled abroad was one line of inquiry.
