Octavia Spencer's Lost Women franchise returns to Investigation Discovery with Lost Women of Alaska, shining a spotlight on the cases of two murdered Alaska native women. The Oscar-winning actress exclusively tells Us Weekly why it's so important for her to amplify the stories of missing women. Spencer, 55, tells Us Weekly that "being a citizen of the world and being cognizant of the fact that those most vulnerable in our society are preyed upon" is the reason why she worked to bring these shows to life.
