Existing catalog summary
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.
Existing record notes
- The supplied text labels itself an editorial best-guess transcript rather than a certified verbatim transcript. It resolves likely speech-recognition errors but retains [unclear] markers where confidence is low.
- Digital redactions are preserved exactly as unavailable intervals and must never be reconstructed or treated as evidence of a specific subject.
- The transcript’s spoken opening dates the interview to November 17, 2022. The uploader or earlier listing described November 21; the spoken date is used for this record, while the discrepancy remains unresolved.
- Statements by DuCoeur are witness recollections, not independently verified facts. He reports drinking that night and says he does not remember the 2:26 a.m. connected call.
- Investigators’ questions, assertions, and theories document the interview process; they do not by themselves establish a case fact or final investigative conclusion.
- Phone and text printouts, Grub Truck imagery, the sketch, doorbell footage, and other referenced materials are described in the transcript but are not all attached here as native exhibits.
- The released transcript ends at a recording break at 01:22:41 and may not represent the entire interview or every related recording.
- Names of redacted or unidentified people are not inferred. Relationship labels are used only where the transcript supplies them.
- Acquisition credit corrected following Julez of all Trades’s September 10, 2026 correction, approved by the archive owner. This credit identifies the records requester, not the issuing agency or the author of statements in the records.
- The previously linked YouTube release was removed after a date-mismatch report. This page now links to the corresponding November 17 audio part. The existing editorial transcript explicitly identifies November 17; its timing has not been newly aligned against the replacement audio.
