There is increasing police presence near the residence of Annie Guthrie amid ongoing investigations into the disappearance of her mother, 84-year Nancy Guthrie.
Two armoured SWAT vehicles from the Pima County Sheriff's Department were seen on Annie Guthrie's street on Tuesday evening, around 6 pm local time, New York Post reported, amid increasing police presence in the area.
Additional FBI agents also swarmed the area, with at least 10 seen fanning throughout the neighborhood.
The SWAT armored vehicles departed the Pima County Sheriff’s parking lot Tuesday evening, Fox News also said.
The sheriff's department also appeared to deploy Bomb Squad and Command Center vehicles, the news outlet said.
One man detained in south Tucson
Separately, a man was detained for questioning by the FBI and the Pima County Sheriff's Department.
The person was detained at a traffic stop south of Tucson, the Sheriff's Department said.
The department, along with FBI agents, also raided a property in Rio Rico, Arizona in connection with the investigation, but it was not clear whether the property has any connection with the detained individual.
CCTV footage released by FBI
The police deployment, detention, and searches on Tuesday come hours after the FBI publicly released surveillance footage from the night of Nancy Guthrie's disappearance.
“Over the last eight days, the FBI and Pima County Sheriff’s Department have been working closely with our private sector partners to continue to recover any images or video footage from Nancy Guthrie’s home that may have been lost, corrupted, or inaccessible due to a variety of factors - including the removal of recording devices. The video was recovered from residual data located in backend systems,” FBI Director Kash Patel said, releasing the images.
“Working with our partners - 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,” he added.
