The disappearance of 84-year-old Nancy Guthrie, mother ofTodayhost Savannah Guthrie, has taken another unsettling turn. Investigators in Tucson remain tight-lipped about potential vehicle evidence, yet reports emerged of asilver truckseen in her neighbourhood around the time she vanished.

With a trail of blood droplets leading from her front door to the circular driveway and no confirmed vehicle publicly identified by police, online sleuths are now asking one pressing question. Was there a second person waiting behind the wheel?

One of the most haunting details in the case is the reportedblood droplet trailthat begins at Nancy Guthrie's front door. According to some accounts, the trail stops near the circular driveway. For many observers, that detail alone suggests she was placed into a vehicle.

The layout of the property has only added to the intrigue. The front door opens onto a half-circle drive that allows a car to pull in and out without turning around. If someone was waiting in a vehicle, it would have been a quick and direct exit.

Yet no vehicle has been formally described by law enforcement. No make, no model, no colour. For a case that has generated thousands of tips and weeks of investigation, the silence around a potential getaway car has struck many as unusual.

Some residents have since claimed that a silver truck was seen in the neighbourhood, reportedly drawing the attention of FBI agents during door to door enquiries. Whether that vehicle is significant remains unconfirmed.

Thetwo-man theoryhas since gathered pace online. Some believe themasked figure captured on doorbell footagewas not the first person on scene, but rather someone tasked with disabling the camera after an accomplice had already entered the home.

The man seen in the footage appeared calm and unhurried. That detail has led some to suggest he felt secure because someone else was already inside.

Another theory suggests a division of roles. One person subdues Guthrie inside the house. A second person, possibly acting as a driver, pulls the vehicle up to the front door once the scene is secure. The camera is then removed before Guthrie is carried outside, explaining the absence of footage showing her being taken.

There are also questions about how an elderly woman weighing around 150 pounds could have been moved without assistance. While it is not impossible for one individual to carry her, many argue it would have been far easier with help.
