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 two-page Moscow Police Department chain-of-custody report for case 22-M09903 and evidence 22M-1810, described as Item 11, a tan K-BAR sheath with a USMC logo found on a bed in a third-story bedroom.

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. The reporting party said children found it while playing. Deputy L. 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 Moscow Police Department custody report for incident 22-M09903 and evidence number 22M-1839, described as “Item 40 Blood Swab” from the “F3 South closet wall.” It records booking at 9:34:47 a.m. on November 14, 2022 and receipt/booking at 4:59:25 p.m. on November 15, both associated with Brett Payne and the reason “Send to Lab.” It records legal-defense viewing by Jeff Talbott on April 7, 2023 for photography. The report does not state the swab’s biological profile, test result, source individual, collection method, packaging condition, lab accession number, or whether “blood” was analytically confirmed.
A Moscow Police Department custody report for incident 22-M09903 and evidence number 22M-2094, described as “Item 258 Swab,” brand “DNA Swab,” owner number 428834. The comment says the swab came from a redacted person or source, was collected by ISP Detective Hoxie, and was submitted directly to the ISP laboratory. The log records booking by Dustin Blaker at 1:19:04 p.m. on November 23, 2022 and receipt/booking on November 25 with the reason “Driven back from Lab by 108.” It does not identify the swab subject, explain radio/identifier 108, report a DNA result, or include the laboratory chain before MPD booking.
A later three-page export for the same MPD evidence number 22M-1810 / Item 11 K-BAR knife sheath documented in Record 017. It lists custody events from November 2022 through July 2025, including laboratory-related transfers and later review/location changes. This is a separate report export, not a second sheath or newly collected evidence item.
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.

One of six preserved mailbox exports of a May 9, 2023 exchange identifying the knife-sheath swabs and extracts. The exchange states that Lab Item 22 was a portion of the extract from swab 1.1, that Item 22 went to Othram, and that no material had been received back at the time of the email.

A four-page Moscow Police evidence/property receipt documenting items collected at the 1122 King Road scene. Legible entries include fingerprint lifts, swabs, electronic devices, a knife sheath, clothing, and other items tied to specific rooms or exhibit numbers. Handwriting and redactions make some entries uncertain, so the original page images control over OCR.
