The drive to Huron
On the morning of November 13, 2013, Rachel Cyriacks left her temporary job at Performance Pet in Mitchell, South Dakota, climbed into her silver 1995 Chevy pickup — South Dakota plates 4CH-634 — and drove toward Huron. Cell phone records traced her to a gas station in the Huron area, where, her husband Bradley later told investigators, she picked him up.
What happened next comes only from Brad’s account: Rachel drove them to their home in Woonsocket, where they stayed briefly. Then she drove him back to Huron and dropped him at a friend’s house. That, he says, was the last time he saw her.
A week passed. Rachel’s mother hadn’t heard from her — unusual enough that she went to the house herself. Nothing was out of the ordinary. No sign of a struggle. Just silence where her daughter should have been.
In December 2013, the family’s gray-and-black Silverado turned up on a bee farm near Huron. It had significant damage to the undercarriage — the kind of damage that comes from driving hard over rough ground. Law enforcement asked farmers across Beadle, Sanborn, and Davison counties to check their fences, fields, and secondary roads for matching damage. And there was one more absence inside the Woonsocket house: Rachel’s green, pink, and white quilt was gone.
Who Rachel was
Rachel Lucille Cyriacks was 30, a mother, a worker picking up a temporary job at a pet business in Mitchell, living in the small town of Woonsocket. The missing-persons poster the state still circulates describes her in the concrete language of identification: 5’5″, sandy brown hair that may have had blond highlights, hazel eyes, a dimple on her right cheek, scars on her abdomen, and tattoos that told pieces of her story — “Bradley” inked on the left side of her neck, the Playboy bunny on her left hip, a tribal heart on her lower back, flowers and the initials “RJ” on her right forearm.
She had people who noticed when she went quiet. A mother who drove over after a week. An attorney general who, ten years later, would say her name out loud at a press conference and ask the state to bring her home.
The investigation
The South Dakota Division of Criminal Investigation has treated Rachel’s disappearance as involuntary from early on — and has said plainly that her husband Brad was the last person known to see her alive. He has not been charged with any crime in connection with her disappearance and is presumed innocent.
The truck was the first real evidence: found a month later at the bee farm, undercarriage wrecked, suggesting it had been driven somewhere it shouldn’t have been. The missing quilt — a bulky, personal item — suggested someone wrapping something, or someone taking comfort. Investigators have never said which reading they favor.
Tips have come in waves. In November 2023, on the tenth anniversary, Attorney General Marty Jackley announced a reward of up to $25,000 — funded through the U.S. Department of Justice’s Equitable Sharing Program — for information leading to arrest and conviction. “There are people who know what happened to Rachel 10 years ago,” Jackley said. “It is time to bring Rachel home and we are providing this reward as a further incentive to convince those who know to finally step forward.”
In December 2023, Jackley announced investigators were analyzing new tips: DCI agents interviewing additional witnesses for the first time, re-interviewing others, analyzing items from a search near Huron, conducting more searches elsewhere in the state. Search crews worked a farm along the James River just north of Huron — adjacent to where the truck had been found — with multiple agencies participating. “Ten years is too long for Rachel’s family to wonder what happened to her,” Jackley said. “It is time to bring her home.”
Theories: what might have happened
Foul play by someone who knew her movements. The state’s posture — involuntary disappearance, reward for arrest and conviction, the husband as last known contact — points here. The damaged truck and the missing quilt suggest a body moved and wrapped. What undercuts a charge: no remains, no forensic public link to anyone, no witness to what happened after the Huron drop-off. Brad Cyriacks has not been charged and is presumed innocent.
An accident on rural roads. The undercarriage damage could mean the truck went off-road — a crash, a ditch, a field. But the truck was recovered, Rachel wasn’t in it, and the quilt’s disappearance doesn’t fit a simple wreck.
Voluntary disappearance. Nothing supports it: no contact in thirteen years, no financial trail described, a mother and children left behind, and the state’s explicit classification of the case as involuntary.
