The founder of The Second Floor (T2F) was shot four times at close range as she left her café in Karachi’s Defence after hosting an event. Institute of Business Administration (IBA) graduate Saad Aziz masterminded Sabeen's murder. His cohorts were highly-educated individuals too.
Mahmud was born in Karachi where she got her early education from. Later, she moved to Lahore and got admission in Kinnaird College.
T2F is designed to enable discussion on human rights, peace-building, justice, environment, social development and intellectual poverty alleviation.
People on social media are paying their tributes to the human rights champion.
Journalist Ammara Ahmed said: "Rest in Peace, Sabeen. We remember everything you stood for with gratitude and will always try to follow your example".

Twitter user Abeera Ashfaq said: "It’s been 4 years since Sabeen’s murder but it feels like 6 or 7. Because a life-time of global grief cascades to drown the past. But we remember."

Sociologist Nida Kirmani said: "Four years after her death, she continues to inspire those who knew her and those who did not. Students who were children at the time of her death draw strength from her example. Folks in places far from Karachi pay tribute to her commitment and her bravery."
