Have you seen these Americans?

My mother in law is 60 and her husband is 70. They landed in Rome on the 15th at 720 am. Last heard from at the Prima Vista Lounge at 131pm the 15th.

They were supposed to meet family visiting too in Florence. They were to take a train but were told it wasn't running. Her phone was tracked all day until it died 12 hours later in the area but did not move all day long.

Missing persons was filed in Florence and the Rome and Florence consulates are aware and looking. Please, if you have seen them at ANY point call the police or let me know ASAP.

They have no phone and are 60 and 70. He's tall, 6 foot 4 inches and she's loud when she's speaks. They're not hard to miss. Please help!
