OPP still needs help in Karen Caughlin case

December 14, 2017 By Alice

Karen Caughlin

In the Ontario Provincial Police (OPP) latest press conference they told the public that Karen Caughlin was most likely unintentionally killed by a motorist in 1974. The papers called it “shedding a new light on the case” but I disagree. We already knew she was struck by a car. The question is was it unintentional or not. […]

Is this the car that killed Karen Caughlin?

April 25, 2012 By Alice

Karen Caughlin

A 1970 Plymouth Road Runner, could this be the car that killed Karen Caughlin? The paper Sarnia This Week wants to know. Several people have wondered about this.

Author Notes

On this website, I write about old, unsolved cases. Most are from the pre-DNA era and are in need of renewed media attention. I only do research and leave the active investigation of these cases to the professionals.

My posts are about homicides, missing and unidentified people, wrongful convictions, and forensics as related to these cases.

On book reviews: I only review select works of true crime, crime fiction, and historical fiction/mysteries. The stories have to fit my website's theme and research. It remains my prerogative to not review a book.

My database has over 325 cases listed by the victim’s last name. You will find a brief description there as well. The database will always be free to the public to use. You cannot buy ad space on my website, ever.

All writing suggestions that come in by email are added to my to-do list in the order in which they were received. Please be patient. My to-do list is very long but no case gets dropped and I will get back in touch.

Defrosting Cold Cases is NOT an organization. It is my brainchild.

If you have any questions about my website please check the Frequently Asked Questions (FAQ) page, the about page, and the tabs in both menu bars. If you still cannot find the answer there, please contact me.

Thank you,

Alice de Sturler

Richard Lapointe

Category: ALL POSTS

In March 2015, the Connecticut State Supreme Court ordered a new trial for Richard lapointe. On Oct 2, 2015, International Wrongful Conviction Day, Richard was set free. The judge ruled that he cannot be retried for the 1987 rape-murder of Mrs. Bernice Martin. Richard Lapointe died on Aug 4, 2020 of Covid19 complications.

In 1987, someone killed Bernice Martin. I hope that she will not become a forgotten file.
