The cameras recorded nothing suspicious, the sources said.
Investigators were able to observe several people in the back and side yards over an unspecified period prior to the abduction. After Nancy Guthrie was taken, law enforcement officers are seen near the pool.
The Pima County Sheriff’s Department said Friday that it “continues to analyze various forms of evidence in the Nancy Guthrie case, including material from laboratories as well as images and videos captured by cameras.”
“At this time, we will not comment on the details or status of this analysis,” the statement continued.
The FBI has previously released photos and videos of an unknown armed suspect in front of Nancy Guthrie’s home on the morning of her disappearance, appearing to tamper with a security camera.
The masked man appears to have been at her front door earlier than Feb. 1, sources familiar with the investigation told ABC News.
