Where is former Dannemora prison employee Joyce Mitchell?

David Sweat was serving a life sentence for the 2002 killing of Broome County Sheriff's Deputy Kevin Tarsia when he and Richard Matt, also serving a sentence at the same prison, launched an escape that sparked a three-week manhunt.

The escape was aided by prison employee Joyce Mitchell, who secretly obtained supplies for the prisoners, including lighted goggles and hacksaw blades.

Patricia Arquette, who plays Joyce Mitchell in the series, won the 2019 Golden Globe and Screen Actors Guild Awards for her performance.
