🔎 The Unsolved Murders of the O’Brien Family 🔎
For more than half a century, the O’Brien family of St. Louis—a proud Irish Catholic family with deep roots in law enforcement—has carried a burden no family should bear. From 1952 to 2008, three members of their family were brutally murdered within the city limits, and to this day, all three cases remain unsolved.
Lucille O’Brien (1952): The matriarch, robbed and murdered in her home.
Brady O’Brien (1990): Attacked and killed after stumbling upon a party.
Kelty O’Brien (2008): Shot on his way to work, tied to dangerous rivalries in the courier business.
Their story is also carried forward by Mark O’Brien, who served two decades with the St. Louis Metropolitan Police Department, retiring in 2017. Beyond his service, Mark became the well-known voice of Guns ‘N Hoses—the annual Police and Fire boxing event—and today continues to document and fight for justice in the unsolved murders of his family, even while battling serious health issues.
This week on The Brighter Side of Blue, we sit down with former FBI Agent and investigator Frank Brostrom, and Charlyn O’Brien, sister of Brady and Kelty, to share this family’s story of resilience, heartbreak, and an unyielding fight for justice.
💙 This is more than a crime story—it’s a St. Louis story. A story of service, sacrifice, and a family’s decades-long pursuit of answers.
👉 Join us as we shine a light on the O’Brien murders and ask for your help in spreading the word.
