This could be a breakthrough.
When Patz went missing, the basement floor was “newly poured” and was not touched in the original search for the 6-year-old. But, after Manhattan DA Cyrus Vance Jr. opened up the case again in 2010, the architecture of the cellar became an area of interest. FBI officials have been tearing it up in search for anything that could give them some sort of direction to who or what was behind the fate of the missing boy.
The main suspect was and still is Othniel Miller, a carpenter that met the boy the day before and gave him a dollar. Along with his sometimes strange behavior, these are the only pieces of evidence authorities have against the now-75-year-old man, who denies all involvement, and it’s not much to work with.
