India, Feb. 27 -- On Thursday, reporters outside Nancy Guthrie's home near Tucson noted fresh activity as the search for the 84-year-old entered the 26th day. Vehicles with surveillance equipment from the company Comcast were seen at the house, escorted by deputies from the Pima County Sheriff's Department (PCSD).

Thursday's activity at the home in Catalina comes after FBI and PCSD officials prepared the home for handover to the family on Wednesday, according to Fox 10 Phoenix.
