A long-unsolved case in Massachusetts has finally reached justice. John Carey, known as the “Hamilton Strangler,” has been sentenced to life in prison without parole for the 1986 murder of Claire Gravel.
The conviction comes nearly four decades after Gravel’s death, marking a significant breakthrough made possible by advances in DNA technology.
The Crime That Went Cold for Decades
Claire Gravel was a 20-year-old student at Salem State University and worked at National Braille Press.
On June 29, 1986, she was last seen after being dropped off near her apartment following a night out. Her body was later discovered in a wooded area near Route 128 in Beverly.
Investigators determined she had been strangled, but despite early efforts, the case went cold for years.
Why it matters:
Cold cases like this often depend on new technology or evidence to reopen investigations decades later.
DNA Evidence Breakthrough
The turning point came through DNA analysis.
Prosecutors said Carey’s DNA was found on the black tank top used to strangle Gravel. This evidence was matched using a sample Carey provided after a separate conviction years later.
His DNA had been entered into the national CODIS database, eventually linking him directly to the crime scene.
Why it matters:
DNA databases have become one of the most powerful tools in solving long-unsolved crimes.
Previous Conviction Led to Identification
Carey had previously been convicted in a 2008 attempted murder case, which required him to submit a DNA sample.
In that incident, prosecutors said he choked a woman inside her home in Hamilton, but she survived.
That sample ultimately became the key to solving Gravel’s murder.
Prosecutors Outline Motive
During the trial, prosecutors argued that the killing was driven by Carey’s sexual interest in strangulation.
This detail played a central role in establishing intent and connecting the earlier attempted murder to the 1986 case.
Family Waited Nearly 40 Years for Justice
At sentencing, family members described Claire Gravel as full of life, with dreams of studying law, raising a family, and exploring the world.
They called her a “ray of sunshine” and expressed both grief and relief after decades of waiting.
Officials emphasized the persistence of investigators, noting that the case was never abandoned.
Sentence and Current Status
Carey, now 66, was convicted of first-degree murder and sentenced to life in prison without the possibility of parole.
He is already serving a 20-year sentence for the earlier attempted murder case.

This case is a powerful example of how justice can still be achieved, even after decades.
Advances in forensic science, combined with persistent investigative work, helped bring closure to a family that waited nearly 40 years.
While no sentence can undo the loss, the conviction ensures accountability — and serves as a reminder that cold cases are never truly forgotten.
