Authorities continue to investigate the disappearance of 84-year-old Nancy Guthrie as the case remains active with no arrests and no publicly identified suspects.

Recent reports have mentioned new statements from family members, including Annie Guthrie and her husband. However, officials have not confirmed whether these statements have significantly changed the direction of the investigation. Authorities continue to review all available information as part of an ongoing effort to establish a complete timeline of events.

Nancy Guthrie disappeared from her home in Tucson’s Catalina Foothills during the early hours of February 1. Since the beginning of the case, investigators have treated her residence as a crime scene, and the FBI has offered a $100,000 reward for information that could help locate her or identify those responsible.

Here are the five main areas investigators continue to focus on.

1. The Timeline of Events
According to Pima County Sheriff Chris Nanos, Nancy Guthrie had dinner with relatives on January 31 before being dropped off at her home at 9:48 p.m. Her garage door reportedly closed two minutes later.

Several key events followed:

1:47 a.m.: Her Nest doorbell camera went offline.
2:28 a.m.: Her pacemaker lost its connection with her smartphone.
February 1: She was officially reported missing.
Authorities believe she may have been taken from her home during this timeframe, though investigators continue to gather evidence to determine exactly what happened.

2. The Masked Individual Captured on Camera
Surveillance footage from Guthrie’s Nest camera reportedly shows a masked person near the residence carrying a backpack and an item believed to be a holster.

FBI analysts have estimated the person’s height to be approximately 5 feet 9 inches to 5 feet 10 inches, with a medium build.

Investigators have publicly identified several items visible in the footage, including a black Ozark Trail backpack and a Strategy brand hip holster, both commonly available through retail stores.

Authorities have not identified the individual shown in the video.

3. DNA Evidence Recovered From the Home
Investigators recovered DNA belonging to an unidentified individual inside the home. Officials have stated that the DNA does not match Nancy Guthrie, family members, or household workers.

Authorities also recovered multiple gloves within a two-mile radius of the residence. One glove believed to resemble the one seen in surveillance footage contained an unidentified male DNA profile.

Officials have not publicly announced whether any database searches have produced a match.

4. Blood Found Near the Front Entrance
Investigators confirmed that blood discovered on the front steps belonged to Nancy Guthrie.

Authorities have declined to provide additional details about when the blood was deposited or what other forensic evidence was recovered, citing the ongoing investigation.

5. Digital Forensics and Pacemaker Data
Nancy Guthrie’s pacemaker provided investigators with an important timestamp when it disconnected from her phone.

Authorities later used specialized equipment to search for Bluetooth signals that might have originated from the device, but those efforts did not produce results.

Investigators are also analyzing:

Home surveillance footage
Roadside cameras
Cell phone tower records
Digital location data
Thousands of public tips
Residents living within a two-mile radius have been asked to provide any available video recordings captured between January 1 and February 2.

Officials also confirmed that a recent tip led investigators to search a nearby home and vehicle and temporarily detain three individuals. No charges were filed, and no suspects have been publicly identified.

As the investigation continues, authorities say they remain focused on following evidence rather than speculation. While several significant clues have emerged, many questions remain unanswered, and investigators continue to encourage anyone with relevant information to come forward.
