Overview of Missing & Murdered Introduces: The Jaclyn Ferland‑Smith Case

This episode (Someone Knows Something — Season 10, episode 1) introduces the disappearance of Jacqueline “Jackie” (Smith) Ferland, a 40‑year‑old Canadian who vanished from Playa del Coco, Costa Rica, on August 17, 2021. Host David Ridgen outlines the known facts, family concerns, conflicting accounts from Jackie’s husband Sébastien Ferland, local witnesses and volunteers, and the early course of the police inquiry (OIJ). The episode sets up an investigation into what happened, highlighting gaps, allegations, and why Jackie’s case remains unresolved.

Key facts & timeline

  • Disappearance date: Night of August 17, 2021 (last seen at the home Jackie shared with her husband).
  • Report filed: Sébastien called Jackie’s parents on August 18; a missing‑person report was filed August 19, 2021.
  • Items reportedly left at home: Jackie’s cell phone, credit cards, and wedding ring (to be independently confirmed in the series).
  • Location: Casa/house in the Casique development above Playa del Coco (northwestern Pacific coast of Costa Rica).
  • Medical history: Jackie had a Canadian diagnosis (2019) of schizoaffective disorder per a medical report cited in the episode; medications listed in documents include escitalopram and aripiprazole, though it’s unclear which she was taking at disappearance.
  • Police involvement: Costa Rica’s OIJ investigated. Jackie’s parents say OIJ told them they suspected Sébastien was involved; no charges or arrests were made as of the time of the episode.

Main people introduced

  • Jacqueline “Jackie” (Smith) Ferland — missing person; originally from Abbotsford, B.C.; trained in kinesiology at SFU; vegetarian, physically active.
  • Sébastien (Sébastien) Ferland — Jackie’s husband; ex‑Canadian Armed Forces vehicle technician (retired on disability). He reported Jackie missing and claims she left while he was in the shower.
  • Colleen and Gordon Smith — Jackie’s parents; travelled to Costa Rica to search and became frustrated with the situation and local responses.
  • Candace — Jackie’s sister (contacted by Ridgen).
  • Krista Marshall — local resident and admin on a “Search for Jacqueline” Facebook page; met and spoke with Ridgen; recalls communicating with Sébastien and seeing him reference distressing messages from Jackie.
  • David Ridgen — host/investigator (Someone Knows Something), undertaking interviews and fact‑finding in Costa Rica.
  • OIJ — Costa Rica’s investigative police (equivalent of federal investigators).

What the episode documents (evidence, accounts, contradictions)

  • Sébastien’s account (public video interview on Pepito Live): He says Jackie had been experiencing paranoia and mental‑health crises, became “distressed,” and left suddenly while he was showering. He denies involvement.
  • Family view: Jackie was generally high‑functioning, health‑conscious, and unlikely to disappear voluntarily into the jungle at night. Family members received normal, pleasant texts and photos from Jackie in the months prior.
  • Messages and history: The episode cites text examples showing normal family interaction. Krista and others say Sébastien showed them messages indicating Jackie was distressed on the day she disappeared; Ridgen wants to see those messages firsthand.
  • Relationship issues: Family recounts heated fights between Jackie and Sébastien, some texts allegedly from Jackie claiming he said things like “I will kill myself” and blamed her—these claims are reported by family and require Sebastien’s response/verification.
  • Police behavior: Jackie’s parents say police told them to leave the house and later told them they suspected the husband—a claim the episode flags and Ridgen aims to corroborate through files/interviews.
  • Prior episodes of leaving: Family and others say Jackie had left before overnight on one or two occasions (stayed in nearby hotels) but always contacted Sébastien to say she was OK; on this occasion she did not.

Theories, open questions, and investigative priorities

  • Voluntary disappearance or suicide: Jackie had a schizoaffective diagnosis and previous mood/psychosis history, so suicide is considered a possible explanation, but family and friends emphasize her functional life and patterns that make this uncertain.
  • Foul play, possibly involving Sébastien: OIJ reportedly told the parents they suspected the husband; community suspicion and inconsistencies in accounts fuel this theory. Sébastien denies involvement.
  • Other possibilities: Accidental death (e.g., in local terrain) or third‑party involvement—both raised due to items left behind and the remote, dark location.
  • Priority investigative actions suggested by the episode: obtain OIJ investigative file, review the timeline and physical evidence (phone, cards, ring), examine digital records (messages, location data), interview Sébastien in detail, locate and interview guardhouse/gate witnesses, and verify the messages Krista referenced.

Notable quotes & moments

  • From Sébastien (Pepito Live interview): “She had issues…too much stress…she had paranoia…by the time I basically came back to myself…she was just gone.”
  • From Jackie’s family/friends describing Jackie: “She was really fast…really dedicated…a healthy, active lifestyle.” — contrasts with descriptions of recent mental‑health struggles.
  • Parents’ recounting of police comment: “They think that husband, Sebastian, was involved.”
  • Krista on community reaction: “For the first year after this happened I was kind of a mess…how can a woman just go missing and we put out all that effort to find her and she’s still missing?”

Tone, structure & what this episode does in the series

  • Purpose: Introduces the case, establishes stakes, presents conflicting narratives, and frames the investigation Ridgen will pursue across the season.

  • Style: Investigative podcast storytelling with on‑site atmosphere (nighttime roads, guardhouses, local characters) and an explicit aim to verify and follow leads.

Triggers, resources & next steps for listeners

  • Trigger warnings: The episode contains references to suicide and mental illness.
  • Where to continue: Episode 2 (and subsequent episodes of Season 10) will dig deeper into police files, interview Sébastien directly, pursue witness statements, and attempt to corroborate messages and timelines.
