THE STAIRCASE
Sundance, 10:00 p.m. ET
Part 1 of 8. This 2004 documentary series has been updated, with two new installments to finish it off and update the story of Michael Peterson, who in 2001 called authorities to report that his wife had fallen down the stairs, to her death, in their lavish North Carolina home. It’s a call, and a case, that quickly uncovered, and unraveled, an entire different set of mysteries, accusations and surprises – all of which led to Peterson being charged with murder. Even without the update, this Staircase would be worth climbing all over again.
