Risila Binte, 22, hanged herself at home in Dhaka, Bangladesh, at around 2pm on Monday while on a video call with her husband.
Investigators believe marital problems could be behind her death. Binte had been on the catwalk since 2012 and was studying for a degree in English literature at the time of her death.
The couple have a three-year-old daughter who was staying with her grandparents when Binte died.
