Karuhimbi risked her life by sheltering refugees from those wanting to see them dead. Her little house became a safe haven for Tutsis, Burundians and even three Europeans trying to escape violence during the genocide. She reportedly hid people under her bed, in a secret space in the roof, and there are reports that she dug a hole in her fields for people to hide in. She would even shelter babies who had been rescued from the arms of their dead mothers after being left to die. The exact number of people she sheltered is unknown, but it is believed to be around 100-150.
