A retired FBI profiler has suggested that blood found outside the home of Nancy Guthrie may point to a chilling detail about her disappearance.

Speaking on a podcast hosted by Brian Entin, former FBI profiler Jim Clemente said the blood spatter pattern could indicate that only one person was involved in the alleged abduction of the 84-year-old.

According to Clemente, if multiple attackers had been present, they would likely have had full control of the victim and prevented any struggle. Instead, he noted signs suggesting she may have been injured and coughing up blood while on the ground.

He also pointed out that there is no clear evidence so far—such as multiple shoe prints—to confirm the involvement of more than one suspect.

Footage released shortly after Guthrie’s disappearance showed what appeared to be a trail of blood outside her Tucson home, with visible stains leading up to the door. Reports also confirmed that blood was found inside the house.

Another former FBI agent, Maureen O’Connell, previously explained that the blood pattern suggests Guthrie may not have walked out on her own. Instead, the absence of gaps or “voids” in the blood stains could mean she was already unconscious and possibly carried out.

“In my view, she was likely wrapped up and removed from the home,” O’Connell said.
