About Cousins by Blood

Cousins by Blood examines the case against Ivan Cantu, who was convicted in the murders of his cousin James Mosqueda and James’s fiancé, Amy Kitchen. The show’s center is not mystery for its own sake. It is reasonable doubt, built slowly from interviews, statements, physical details, and the hard arithmetic of time. Private investigator Matt Duff leads the investigation with a practical, skeptical style. He lays out a claim, tests it against the known timeline, and then asks what would have to be true for that claim to hold. The early episodes contrast Ivan’s version of the night with Amy Boettcher’s statement, including her account of threats, blood, clothing, keys, and a gun. Then the series widens. Sylvia Cantu remembers the family’s confusion and the events around the bodies being found. Amy’s stepdad, Mr. Kramer, adds another view of Ivan and Amy after the murders. Tawny challenges the idea that Ivan could have left evidence where the state said it was found. A later episode turns a kitchen trash can into a major pressure point, because bloody jeans, socks, and latex gloves allegedly sat near the top without a lid. The show is often strongest in those moments. It does not need a dramatic flourish when a small physical fact creates a large problem. A ring left in a bedroom, a car borrowed overnight, a voicemail from years earlier, a trip to Arkansas, and a disputed account of who feared whom all become pieces of the same larger question. The series is openly concerned with the possibility that an innocent man could be executed. It also spends time with the emotional cost of death row, including Ivan’s marriage, execution paperwork, and the strain placed on people trying to keep the case alive. The tone is grave but accessible. It can be blunt, especially when witness accounts collide, yet it stays focused on evidence rather than shock. Cousins by Blood is best for listeners who like true crime that argues from documents and interviews instead of atmosphere. It asks for patience, and rewards attention to the details other cases might pass over.

Made for: For true-crime listeners drawn to wrongful-conviction cases, contested timelines, and evidence-heavy interviews. It suits people who want a skeptical investigation rather than a polished crime retelling.

What sets it apart: The show’s force comes from private-investigator casework: statements, family interviews, trial fragments, and physical evidence are repeatedly checked against the timeline. Small details become the engine of the argument.

In their own words

Cousins By Blood is a true crime podcast investigation, unfolding episode by episode. In 2000, Ivan Cantu was arrested for the murders of his cousin James Mosqueda and Amy Kitchen, James's fiancé. Now 20 years later, questions about Ivan's guilt or innocence remain and the case has been reinvestigated. New suspects are uncovered, new evidence has been discovered, and the clock is ticking to Ivan's Execution Day.

Best episodes of Cousins by Blood

Short reviews from the PlayNext desk, based on the episodes we processed.

Episode 1: If The Jeans Don't FitMar 25, 2024

A methodical murder case built from timeline details and conflicting accounts.

Matt Duff opens the episode around Sylvia Cantu's account, and Amy Boettcher's statement helps keep the murder story grounded in a tight timeline. The strongest part is how concrete it stays.

Episode 2: When Ivan Met AmyMar 24, 2024

An old voicemail, a disputed account, and a timeline that never quite settles.

The old voicemail gives the episode its best jolt. The case keeps circling the same pressure points: who said what, when it was said, and why the obvious people were not contacted sooner.

Episode 3: Not His First RodeoMar 23, 2024

A timeline-heavy chapter that turns strange claims into hard questions.

This episode tightens the screws on the Kitchen case by placing the competing timelines side by side and asking what actually holds up. The strongest passages return to the 11:30 p.m.

Episode 5: The Trash Can Without a LidMar 20, 2024

A patient evidence piece that turns one trash can into the center of the case.

The episode keeps circling a trash can without a lid, the jeans, socks, and latex gloves that may or may not have been placed there, and the fact that Ivan and Amy were already in Arkansas.

Episode 11: Ivan's WifeMar 14, 2024

A death-row marriage turns a murder case into a race against time.

This episode sits inside a death-row marriage shaped by a death warrant and the long wait that follows it, while the murders of James Mosqueda and Amy Kitchen keep the case from settling into a tidy theory.

Episode 14: What's Amy Been Up To?Mar 10, 2024

A measured case update built from interviews, contradictions, and one sharp thread.

What's Amy Been Up To? follows a recent neighbor interview and folds in Amy's account to keep fear, rumor, and the search for truth in view. The episode moves between what TJ said in October and what Amy later described, which gives the story its shape.
