“I hope they get the suspect, because I’m not it,” Carlos said, according to a video posted on X by CBS reporter Andres Gutierrez.

The Pima County Sherrif’s Department had confirmed police were conducting a court-authorised search at a location in Rio Rico, south of Tucson, Arizona.
The news of the detention came hours after the FBI released images and videos of a masked person at Nancy Guthrie’s doorstep on the night of her disappearance. Authorities said the individual was armed.
“As of this morning, law enforcement has uncovered these previously inaccessible new images showing an armed individual appearing to have tampered with the camera at Nancy Guthrie’s front door the morning of her disappearance,” FBI Director Kash Patel said in a statement on X.
He said authorities had been working to recover images from the home surveillance system that “may have been lost, corrupted, or inaccessible due to a variety of factors – including the removal of recording devices”.
The two short videos show the person approach the front door of Nancy Guthrie’s home, then check the camera before moving away, picking up some vegetation from the ground and using it to cover the camera lens.
Savannah Guthrie shared the new video on Instagram. “Someone out there recognises this person,” she said on Tuesday. “We believe she is still out there. Bring her home.”
On Wednesday, the FBI said it was conducting an “extensive search” in the Catalina Foothills are related to the investigation.
