"One of the coroners to perform the autopsies, Walter McCarron, surmised the sisters' bodies had lain undiscovered behind the guard rail on German Church Road for many days before their eventual discovery, stating that the bodies' markedly preserved condition given the time interval between their disappearance and discovery had been due the frigid temperatures in the weeks prior to January 22, adding that this had been due to recent snowfalls and the frigid climate.McCarron also concluded the girls' bodies had lain undiscovered for more than three weeks because a layer of snow had blanketed the area on January 9, and that this snowfall had rapidly melted in the days immediately prior to their discovery.
