May 26, 2023 By Alice

Photograph AdS

The same flawed and overhauled technology used in forensic arson detection that resulted in Cameron Todd Willingham’s death sentence and that bears eerie similarities to Kenneth Richey’s case, moved a federal jury to award Adam Gray $27 million. Wrongfully convicted, Adam served 24 years in […]

Author Notes

Since 2009, I write about unsolved cases that need renewed media attention. I only do research and leave active investigations to the authorities.

My posts cover homicides, missing and unidentified people, wrongful convictions, and forensics as related to unsolved 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, tone, and research. It is my prerogative to not review a book. Please check the FAQ page for more.

My databases are free to the public. Cases are sorted by the victim’s last name.

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 cannot find the answers there, please contact me.

Thank you,
