Update: A new person was detained for questioning in the Nancy Guthrie kidnapping case, according to Nancy Grace. The individual was detained south of Tucson, late at night, but the Pima County Sheriff's Department has yet to issue a statement on the detention.
The detention comes as the FBI has obtained DNA evidence from the Pima County sheriff's office, which is being tested in a private Florida lab. The FBI is expected to use advanced techniques to analyze the DNA evidence.
While authorities have detained three people in the case, none have been named as suspects. Guthrie was reported missing on February 1, and authorities believe she was taken from her home in the Catalina Foothills near Tucson, Arizona.
