Brad Smith, the partner of missing Utah woman Addi Smith, has confirmed in a new exclusive interview that disagreements over Addi’s planned travel itinerary resurfaced in the final weeks before her disappearance on November 12, 2025. The admission, made public February 23, 2026, coincides with a major investigative development: the recovery of a handwritten November 2025 calendar page from Tawnia McGeehan’s wallet, featuring November 11—the last day Addi was seen alive—circled repeatedly in red ink.

Addi Smith, 29, a mother of two young children and a freelance photographer, was reported missing after failing to return home or respond to messages. Her SUV was discovered partially submerged near the southern shore of the Great Salt Lake three days later, with blood traces matching her DNA found on the driver’s seat and door handle. The case quickly shifted from a possible voluntary departure to a suspected abduction or homicide after cellphone data showed her device traveling north from Layton before going offline around 10:15 p.m. on November 11.

Tawnia McGeehan, Addi’s former mother-in-law, has been under scrutiny since early December 2025. McGeehan’s son—Addi’s first husband—died in a motorcycle crash in 2022, leaving lingering friction over custody, finances, and family dynamics after Addi remarried Brad Smith in 2023. McGeehan was arrested January 15, 2026 on wire fraud charges unrelated to the disappearance, but investigators obtained a warrant to search her belongings after cell records placed her phone near the Smith residence multiple times in early November.

During that search on February 18, detectives located a folded calendar page inside a zippered compartment of McGeehan’s wallet. The single sheet, torn from a pocket planner, lists mundane entries for the month—dentist appointment November 3, oil change November 7, hair appointment November 15—but November 11 is marked with three heavy red circles and the small handwritten notation “A travel.” Prosecutors view the aggressive marking and concealed storage as potential indicators of significance or foreknowledge. McGeehan’s attorney maintains the note was simply a reminder of a family discussion about Addi’s upcoming trip and that the red ink was her usual way of highlighting important dates.

Brad Smith’s interview provides new context to the circled date. He told reporters that Addi first mentioned wanting a short solo trip to Idaho in mid-October to visit cousins and “get some breathing room.” Smith said he initially supported the idea but grew concerned about winter road conditions and leaving the children. “We argued about it more than once,” he admitted. “She felt I wasn’t trusting her judgment. I felt she was running away from our problems instead of facing them.” He confirmed the last major argument occurred November 9 after Addi booked a hotel in Idaho Falls for November 12–14.

Witness statements support the timeline of rising tension. Addi’s sister received a late-night call November 8 in which Addi cried about feeling “suffocated” and said she needed distance to decide whether to stay in the marriage. A neighbor reported hearing yelling from the Smith home around 10:30 p.m. on November 10. Addi’s final text to her sister at 8:47 p.m. on November 11 read: “Packed and ready. Heading out early tomorrow. Love you.” Her phone never connected to cell towers again after that message.

Smith maintains he last saw Addi around 9:30 p.m. on November 11 when she said she was going to grab snacks for the road and would return soon. When she didn’t come back by morning, he contacted family and eventually law enforcement. He voluntarily submitted to questioning, provided DNA, handed over his phone, and passed a polygraph regarding direct involvement, though investigators caution that polygraphs are not conclusive.

The red-circled date has intensified focus on McGeehan. Cell-tower pings show her phone in the vicinity of the Smith residence at 7:42 p.m. on November 10 and again at 6:18 a.m. on November 12—times she claims were related to dropping off early Christmas gifts for the grandchildren. Prosecutors are seeking warrants for her vehicle, home safe, and a small storage unit she rents in Ogden, citing possible trace evidence transfer or additional planning documents.

Brad Smith addressed the renewed scrutiny in the interview, saying the travel dispute “has come back up because people keep asking why she was leaving that night.” He denied any physical altercation and reiterated his cooperation, but acknowledged the marriage had been strained by earlier trust issues stemming from a brief emotional affair he had in 2023. “We were working through it,” he said. “She wanted the trip to think. I wanted her safe. That’s all it was.”

Addi’s extended family has publicly questioned why McGeehan kept the calendar page hidden rather than turning it over immediately. A reward fund managed by Crime Stoppers now exceeds $165,000, and weekly candlelight gatherings continue in Layton’s Heritage Park. Volunteers have combed nearby trails and lake shores under sheriff guidance, though no new physical evidence has surfaced since the vehicle recovery.

The case remains active with the FBI assisting on digital forensics and possible interstate travel angles. Prosecutors have not yet filed charges directly related to Addi’s disappearance against McGeehan or anyone else, but the combination of the red-circled date, Smith’s confirmation of last-minute tension, and McGeehan’s proximity on key days has shifted the investigation toward premeditation rather than random foul play.

For the Smith children, now living primarily with Brad under close supervision, the uncertainty continues. Addi’s sister maintains a daily social-media post asking for tips: “Every detail matters. Someone knows something.” As investigators analyze the calendar page for latent fingerprints, ink dating, and contextual handwriting comparison, that single red circle—once just a mark on paper—has become the most haunting clue in a mystery that refuses to resolve.
