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 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 police incident record titled “Molly McMichael DUI Report.” It is indexed as a discrete background source with its original redactions.

A 2,356-page Idaho State Police Forensic Services production centered on laboratory case M2022-4843 for Moscow Police case 22-M09903, with related ISP Investigations laboratory case M2022-4870 / D22000030 material. The release contains case jackets, submission and item inventories, chain-of-custody and location records, biology and DNA worksheets, STRmix output, CODIS-related documentation, latent-print processing and comparison reports, analyst notes, technical and administrative reviews, correspondence, discovery-packet histories, audit entries, and supporting forms. It records numerous submissions from November 2022 through June 2025 and references suspected biological stains, reference samples, DNA extracts, latent lifts, clothing and other evidence. Individual report language and statistical conclusions must be read in context; this archive record indexes the production and its searchable extraction rather than collapsing thousands of pages into a single forensic conclusion.
A large collection of Idaho State Police investigative supplements for case D22000030. The searchable extraction includes the November 13, 2022 initial call-out, witness and roommate interviews, crime-scene work on multiple dates, photographic and SUAS documentation, evidence transport, phone and video inquiries, search-warrant activity, receipts, hospital checks, WSU and Moscow reports, vehicle and Hyundai Elantra processing, defense evidence processing, and later witness-list follow-up.

The collection records officer narratives, witness recollections, investigative leads and later follow-up; those categories are not interchangeable with independently proven fact.
