Nancy Guthrie has been missing since Sunday, Feb. 1. As the investigation enters its sixth week, billboards have been put up in various states, including Arizona, California, and Texas.

However, former FBI agent Jennifer Coffindaffer is raising questions about the public awareness campaign surrounding Guthrie’s disappearance. While billboards and other promotional efforts are intended to keep the case in the public eye, the agent said that a key element—one that could help focus attention on the investigation—is missing.

The Pima County Sheriff’s Department along with the FBI previously released photos and videos of a potential suspect on Guthrie’s front stoop the night she disappeared. The perp does not appear on the billboards, which Coffindaffer believes could help the case.

“This photo should be next to Nancy’s on the billboards that the FBI put up,” Coffindaffer wrote on X. “The abductor would have hidden Nancy. Likely no one in Texas or California would have ever seen her post abduction, but they could know Porch Guy. I guarantee his friends and family recognize him.”

“Did Porch Guy travel across Statelines to commit this crime like the teens who kidnapped and beat the Scottsdale couple demanding millions in Bitcoin? Millions have no idea Nancy was even abducted including the pizza delivery guy that delivered pizza to Nancy’s house post abduction while sheriff’s officers and dozens of reporters watched,” she continued, adding, “Awareness is key, as is showing Porch Guy’s face. Hoping for a new set of billboards.”
