Tommaso Cioni is seen for the first time along with his wife and sister-in-law, Savannah Guthrie, alongside the makeshift memorial for Nancy Guthrie.

Cioni, in the many public social postings, has been suspected of being involved with his mother-in-law's disappearance, despite assurances from police that the family has been clear of suspicion.

As the investigation continues, questions of whether or not the suspect returned to the scene of the crime have been raised. Are there clues among the flowers and gifts left in the memorial?
