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 one-sheet PowerTime report listing Moscow Police shifts, time off, on-call duty, football-game overtime, and special overtime spanning November 12–13, 2022. It identifies 28 schedule entries and separately lists three Campus Division / U of I–Greek System liaisons. Of particular timeline interest, the evening patrol roster shows Casey Green, Nate Rosendahl, Bransen Stirk, and Jay Waters on 6 p.m.–6 a.m. shifts, with Jacob Tesdahl on 9 p.m.–5 a.m. special overtime for a plain-clothes alcohol emphasis. A schedule records planned staffing, not continuous location, activity, dispatch assignment, or proof that every listed person worked every minute shown.

A six-page Latah County Sheriff's Office report for incident 23L-1392 documenting a KA-BAR knife and black sheath found on the ground near trees at the top of Ash Street near Spruce Street in Genesee, Idaho on March 19, 2023.

Whiting described a black knife with a handle wrapped in black tape-like material, a black sheath, and some rust and dust suggesting it had been in dirt for some time. Property record 1440 lists serial marking “1482 TAIWAN,” a nominal value of $1, and found-property status. The report does not connect this knife to case 22-M09903, the King Road scene, or evidence 22M-1810.

A three-sheet workbook identifying an Amazon account as Bryan C Kohberger and presenting subscription information, 289 click-activity rows, and 57 sign-in-history rows. Click activity clusters on March 20–26, November 15 and 22, and December 6, 2022, including KA-BAR knife, sheath and sharpener product pages plus account/order and deletion-flow pages.

Othram shipping instructions plus duplicate shipment-receipt and chain-of-custody forms for submission/request 21128. The forms record one hand-delivered item from Dustin Blaker, received November 22, 2022 at 3:15 p.m., with no package damage checked. Visible case-ID and item-notes fields are blank, so the packet does not itself identify the evidence item or establish a connection to the knife sheath or another named exhibit.
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.
