Investigators have not identified any persons of interest or suspects in the Nancy Guthrie abduction, Pima County Sheriff Chris Nanos' office repeated Wednesday afternoon.
The Sheriff's Department also said in its updated statement at 4 p.m. Wednesday that it received a report on Jan. 4 of a possible trespassing in the 6700 block of North Longfellow Drive, which maps show is about 2.7 miles from Guthrie's home near North Campbell Avenue and East Skyline Drive.
Savannah Guthrie and her siblings release a statement on Instagram pleaing for their mother's return. Nancy Guthrie was reported missing on Sunday, Feb. 1.
"This case, in addition to all other cases within a close radius to the Guthrie home are being reviewed," the statement said. It was issued after the tabloid news site TMZ reported Wednesday on the possible trespassing in early January about 10 minutes from Guthrie's home.
The Sheriff's Department noted it is working in conjunction with the FBI on the investigation of what it calls an abduction of Guthrie from her home Saturday night or early Sunday.
"While our detectives have turned the home over to the Guthrie family, this is still an active investigation — so you may see activity in the area during the process," the sheriff's statement added.
No other updates were given.
Nanos told the New York Times Tuesday night that Guthrie, 84, had dinner with her daughter Annie and her son-in-law on Saturday, and that the son-in-law dropped Guthrie off at home about 9:45 p.m. and made sure she was inside safely before leaving.
Nancy Guthrie, who is also the mother of NBC "Today" show host Savannah Guthrie, was reported missing about noon Sunday after failing to show up at church.
Nanos also told the Times that investigators have talked to family members and all have been cooperative.
The Sheriff's Office said Nanos is not doing interviews Wednesday and that his next press conference in the case will be held Thursday at 11 a.m.
He had told CBS News Tuesday that investigators analyzed and were taking seriously a possible ransom note received Monday by a Tucson news station, and that the FBI made the decision to share it with Savannah Guthrie. Nanos "would not confirm" the accuracy of information included in the note nor whether the note was considered to be legitimate, the network reported.
Nanos said at a press conference Tuesday that investigators don't know whether Nancy Guthrie might have been targeted because of Savannah's high public profile. "We don't know. We're going to assume both sides of that" for investigative purposes, he said.
Nanos told the New York Times that night that he has spoken with Savannah Guthrie and her security team and they were not aware of any previous threats to her or her family.
Savannah, who was raised in Tucson and is a University of Arizona.
