Savannah Guthrie releases a new video acknowledging the possibility that her mother may have passed on, but the family is hanging on to hope.

They are now offering a million-dollar reward, bringing the total to over $1.2 million dollars.

As the investigation continues, investigators say that the video of a man with a backpack on Guthrie's front porch and a still of a man in the same location, but without a backpack, could be from a different day. Meaning, the suspect may have visited the home multiple times.
