The Turpin Family
Season 44, episode 7 of 20/20 (ABC broadcast 11/26/21), features an interview with two of the Turbin sisters. The Turbin parents kept their children inside 24/7, often chaining them to their beds. One finally broke out and reached the police. I'd be interested to learn about the micro-expressions on the parents' faces during the camera footage where the sheriffs enter their home. But I'm also very touched by the overt emotions on the sisters' face during the interview. At about minute 29, there's a wordless exchange between the sisters, where one clearly reads the other's emotions. You can almost hear the unspoken conversation.
Such brave young women!
