It is not clear why "Alpine Fields" is written on the wall with blood. The Fields family consisted of David, Anne and Lauren. Their neighbor Roger was not even a Fields. The term "Alpine" does not show to help in locating the family. If there was more than one family by the name of Fields, Alpine might have been added to help in locating them, but it seems far-fetched. A first name for any of the family members, such as "David Fields in Alpine area", would have been more directly helpful.
