Tommaso Cioni is seen for the first time along with his wife and sister-in-law Savannah Guthrie along side 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?

Despite a reward of up to $1,000,000 and thousands of leads coming in, the best investigators can say is that the investigation is "definitely closer."

The search includes combing for a key piece of missing evidence: the suspect's cell phone. Sheriff Chris Nanos says cell towers in the area have been pinging, among other leads, in an effort to connect a digital trail.

He acknowledges that there is a lot more data, leads, and tips to be looked at.
