Welcome to Arrest Stories. A fifty-five-year-old Iowa man has been arrested in connection with a twenty-two-year-old cold case murder of a Colorado woman who was found stabbed to death beside a road in two thousand three. Here's what may have happened.
On Monday morning, Dubuque Police arrested Robert McClain on a warrant from Adams County, Colorado, potentially bringing closure to a case that has haunted investigators for over two decades. The arrest stems from the brutal murder of twenty-nine-year-old Rosa Arguello, a member of the Hopi Tribe who was found dead on October seventeenth, two thousand three.
Arguello's body was discovered in a field beside Quebec Street in the twelve thousand block of Thornton, Colorado's northern area. She had been stabbed multiple times and left on the roadside. The young mother, who lived in Thornton with her children, became the victim of what would become one of the area's most enduring cold cases.
The breakthrough came when Dubuque Police received information suggesting McClain might be connected to the Colorado homicide. Working closely with the Thornton Police Department, investigators began piecing together evidence that had remained dormant for years. Thornton Police obtained a search warrant for McClain's residence as part of their renewed investigation.
McClain's troubled history includes a disturbing incident from February two thousand fourteen, when he was charged with attempted murder after attacking his wife. During that same year, McClain shot himself in the face but survived the self-inflicted wound.
The collaborative effort between Iowa and Colorado law enforcement represents the kind of interstate cooperation that often proves crucial in solving cold cases. Thornton Police expressed their gratitude for the partnership, stating, "We are grateful for our partners at Dubuque PD and will continue to work closely with the Seventeenth Judicial District Attorney's Office to pursue justice for Rosa and her family."
Arrangements are currently underway to extradite McClain from Iowa to Colorado, where he will face charges related to Arguello's death.
All suspects presumed innocent until proven guilty in a court of law. Do not take this report as factual, always verify facts. Thanks for watching Arrest Stories.
