Mina Smallman is set to tell the story of her two daughters' murders in a new Stacey Dooley documentary for BBC Two.
Bibaa Henry, 46, and Nicole Smallman, 27, were reported missing on June 6, 2020 - having not returned from Bibaa's birthday celebration the night before in a London park.
The two sisters had been brutally murdered, with their bodies found the next day. The case has subsequently led their mother Mina, 65, "down a path of activism" to fight for a "proactive approach to women's safety".
