This is CNN Breaking News.
Good morning everyone.
I'm Audie Cornish and we begin with this breaking news in the search for Nancy Guthrie.
A person who was detained for questioning in connection to the case has now been released.
This according to her affiliate KNXV and it's just one of the major developments.
Authorities released this video earlier Tuesday showing a masked armed person at Guthrie's door the night she vanished.
It was obtained from her doorbell camera.
We do not know if the person they were questioning has any connection to this footage,
and as of yet, no one has been charged.
Then, last night, CNN learned that a house and car had been searched.
It all happened in Rio Rico, Arizona.
That's about 60 miles from Tucson, where Guthrie was last seen.
Investigators were at the house until a few hours ago,
and CNN spoke with a woman who said it was her home that they'd been searching.
I don't know who she is.
I don't know anything about her.
They only said that they gave a tip that she was in my house.
And I told them, you can go in and search my house.
There's nobody there.
I have nothing to hide.
