British aid worker Elisabeth Jane Ross, 38, from Edinburgh, was found dead in a suitcase in Athens on 18 July, and Afghan boxer Sharif Ahmadzai is in custody in connection with her death. New forensic details suggest she may have been given, or forced to take, an antidepressant to sedate her before she was killed, adding a disturbing new dimension to a case that has drawn attention because of Ross's long-standing charity work with refugees in Greece.

Toxicology tests found traces of fluoxetine in Ross's system, in a quantity small enough to suggest she was not a long-term user, leading police to suspect it was administered shortly before her death to calm her. Further lab analysis has been ordered after initial tests proved inconclusive on cause of death, partly due to decomposition of the body. Ahmadzai, who has been charged with intentional homicide, robbery and illegal firearm possession, denies killing Ross but has admitted moving her body to the derelict building where it was discovered and stealing over £8,500 using her credit cards; he is being held at Athens' Korydallos Prison, where he was reportedly badly beaten by fellow inmates shortly after arriving.
