The body of Elisabeth-Jane Ross, a 38-year-old Briton, was discovered inside a suitcase in the Kypseli neighbourhood of central Athens last month. A homeless man found her on 18 July in an abandoned lot on Evelpidon Street.
Greek police have deployed their entire homicide division to investigate the case. Police spokesperson Konstantina Dimoglidou stated that they are in contact with other police forces and are determined to solve it.
Ms Ross had arrived in Athens on 26 June from Edinburgh for a holiday. She had connections to Greece, having worked with homeless people and been involved in charitable work. She was publicly identified on Wednesday, four days after authorities announced the body was that of a Briton based on fingerprint matching.
Initial examinations of her remains were inconclusive, with pathologists suggesting she had likely been dead for several days before discovery. There were no evident injuries or signs of struggle on her body. DNA analysis of the suitcase has not provided evidence linked to a suspect.
Investigators are intensifying their search of CCTV footage. Police are focusing on Ms Ross's movements between 15 July, her last known contact with friends, and 18 July. Her mobile phone was reportedly used days after her death, with messages sent to her father, who believed she was alive. Authorities believe these messages were sent to delay her being declared missing.
