It’s been four years this month since Colleen Shipman‘s peace of mind was shattered by the unfathomable actions of Lisa Nowak.  Tonight on ABC’s 20/20, Chris Cuomo revisits the case of the astronaut who stalked her love rival halfway across the country.  Colleen, now married to Billy Oefelein and living in Alaska, speaks out for the first time about her traumatic experience in February 2007.

20/20, tonight at 10 eastern, 9 central on ABC.

Out There, my book on the astronaut love triangle case, was released in November 2007 by St. Martin’s Press.
