A secretary has been found murdered at her home in east London.
Ms Thrussell was last seen leaving work on 14 June
Police found June Thrussell's body at her home in Pedley Road, Dagenham, on 17 June after a colleague called to say she had been missing for three days.
Ms Thrussell, 56, lived alone and was last seen leaving work in Ilford on 14 June. A post-mortem examination revealed she had been strangled.
Police have begun a murder inquiry but say, at this stage, they are keeping an open mind about why she was killed.
Detective Inspector Keith Garnish said he wanted to speak to anyone who saw her after 1700 BST on 14 June when she left work.
"Her usual route home was by rail from Ilford to Chadwell Heath station, and from there on foot," he added.
