An in-person Idaho State Police interview of Jack DuCoeur, Kaylee Goncalves’s former boyfriend, recorded at 10:03 a.m. on November 17, 2022. Detective Sergeant Mike Van Leuven and Detective Rich Alderson question DuCoeur about his relationship with Kaylee; his work, bar, ride, and sleep timeline on November 12–13; repeated calls and texts from Kaylee and Madison Mogen; his knowledge of Ethan Chapin and Xana Kernodle; access to 1122 King Road; knives; the house’s door code and locks; the victims’ social circle; and an unidentified rideshare driver. DuCoeur says he left the Corner Club at about 1:00 a.m., reached home shortly afterward, and was asleep around 1:20 a.m. Phone records shown during the interview reportedly include a 2:26 a.m. call from Kaylee that lasted 16.88 minutes; DuCoeur says he does not remember answering or speaking with her and suggests the connection may have been accidental. He also describes the next morning, when he saw police activity near 1122 King Road, approached the scene, and was later placed in a patrol car after identifying himself as Kaylee’s former boyfriend. The interview includes discussion of Grub Truck footage, a neighbor’s doorbell video, a black Baton vape, phone-log and text printouts, a sketch of the house, and the property’s keypad code. This record summarizes what the participants said and what the transcript reports they viewed; it does not independently establish the truth of every statement or the authenticity and completeness of each referenced exhibit.
