The news hit hard for families and communities across Connecticut. It’s a somber reminder of how these mysteries can linger for years.

The Discovery at Mansfield Hollow Lake

On October 5, Connecticut State Police got a call about remains floating near the shore of Mansfield Hollow Lake.

Firefighters arrived first and recovered the remains. Soon after, law enforcement and specialized units took over the scene.

This popular recreation spot in Tolland County quickly became the center of a multi-agency investigation. The search would stretch on for weeks.

Follow-Up Search Uncovers More Clues

Just over two weeks later, on October 21, divers went back into the lake for a thorough underwater search.

They found more remains and a submerged vehicle—a 1996 Mazda B2300 pickup truck. It belonged to Cavanaugh.

Inside the truck were personal items that matched his. The discovery finally put an end to years of uncertainty about what happened to him.

Identification and Cause of Death

The Office of the Chief Medical Examiner determined that Cavanaugh died from drowning and ruled it a suicide.

This matched earlier evidence from 2004, when investigators found what looked like a suicide note he left behind. DNA testing and surgical records from a past shoulder operation confirmed his identity.

Impact on Connecticut Communities

This case hits home for more than just Mansfield. All over Connecticut, towns like Willimantic, Norwich, Hartford, and Middletown have faced similar long-term disappearances.

These cases test first responders, stretch families to their limits, and leave marks that don’t fade quickly.

The Role of Specialized Search Teams

Specialized units—from underwater divers to forensic experts—played a crucial role in this search.

Their training helps them recover evidence in tough spots like lakes and rivers. Teams from places like New London, Bridgeport, and New Haven often join forces for these missions, showing how emergency services across the state work together.

Remembering Robert Cavanaugh

Robert Cavanaugh was 51 when he disappeared. Friends and family in Mansfield and Coventry remember him as quiet and hardworking.

His sudden disappearance on Christmas Eve in 2004 left loved ones without answers for almost twenty years.

Lessons in Long-Term Investigation

This discovery shows how important persistence is in law enforcement. Even after many years, missing persons cases stay open until something turns up.

For everyone involved, it’s a reminder that closure can arrive out of nowhere—sometimes thanks to routine patrols, changing conditions, or new search technology.
