When 23-year-old Aishat Baimuradova fled her home last year, she believed she finally had a chance to live the way she wanted.

Coming from Chechnya, a conservative Muslim republic in Russia, she cut her hair short, stopped covering her head, shaved off part of her eyebrow and posted quirky selfies on Instagram.

She told her new friends she could finally breathe.

In October, Aishat was found dead in a rented flat in neighbouring Armenia. Police say she was murdered.

Two people were seen leaving the building where she was found, including a woman Aishat had befriended not long before her death. Both reportedly left for Russia soon afterwards.

Russians do not need a passport to enter Armenia; their internal ID is enough. That also makes it an easy route for anyone trying to flee.

Chechnya, in Russia's North Caucasus, is often described by rights groups as a state within a state - a place where power is highly personalised and loyalty to long-standing leader Ramzan Kadyrov often over-rides laws and formal institutions.

For years, human rights organisations have documented enforced disappearances, torture and extrajudicial killings in the republic, as well as systematic persecution of those who dissent.

Chechen officials have consistently denied these allegations, complaining of fabrications aimed at discrediting the region.

Several high-profile critics of Chechen authorities have been killed abroad.

Aishat Baimuradova is the first known Chechen woman to have died in suspicious circumstances, not long after fleeing Russia.

Her family tried to persuade her to come back, but when nothing came of it they disowned her, according to SK SOS.

On the night of her death, Aishat was with a woman she had recently met online, who claimed to come from Dagestan, another Russian republic in the North Caucasus.

Armenian authorities say they are investigating two unnamed people in connection with Aishat Baimuradova's murder, but they have released no further details about them.

The fear experienced by other fleeing women has intensified since her death, as they grapple with the reawakening of deep-seated anxieties about their safety.
