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.
A two-page email chain concerning the Moscow Police Department’s SFY2023 Partnerships for Success grant extension. On August 8, 2023, Idaho Office of Drug Policy administrator Sharlene Johnson notified Officer Eric Warner that the extension letter was available. On August 9, Warner told City of Moscow staff that the grant had been extended for a fifth quarter and said he hoped to use the additional period for extra plain-clothing party patrols, which he characterized as reducing campus intoxication calls and deterring underage drinking. Later that day, grants manager Alisa Anderson sent Johnson an executed extension agreement. The chain documents administrative communications and Warner’s stated program rationale; it does not contain patrol reports, outcome data, reimbursement records, or a direct connection to the homicide investigation.

One of three preserved exports of a December 2, 2022 email exchange about sending a digital copy of the signed receipt documenting release of the knife sheath to an officer. The export records the request, approval, and acknowledgment; it should be read with the other two exports because each captures a different mailbox view of the same exchange.

A police incident record titled “16C31883_ ACCIDENT-Redacted.” It is indexed as a discrete background source with its original redactions.
