Even thought I lived in Woodcliff Lake and not Montvale, I will never forget two horrible things growing up....the murder of Joan D'Alessandro of Hillsdale and the murder of the De La Roche family over Thanksgiving weekend in 1976. I remember the headlines like it was yesterday...'family murdered, stuffed in to trunks, son reports finding family dead on military leave'. Driving past the house with it's yellow police tape gave me the chills for years. Even thought the new homeowners renovated the house over the years...it was still the 'De la roche murder'house. I wish you good luck on the movie...I live at the Jersey shore now and just found out that there was a book written about this horrible, terrific murder.
