Some crimes refuse to fade into history. Others harden into legend. But what does the evidence actually show?

Anthrax to Zodiac examines seven of America’s most enduring unsolved crimes—not to sensationalize them, but to look closely at documented evidence, investigative gaps, and disputed conclusions that continue to divide investigators, experts, and the public.

Spanning more than a century, this true-crime anthology explores:

• The anthrax letter attacks following 9/11
• The Zodiac Killer, still unidentified decades later
• The murder of JonBenét Ramsey and its competing theories
• The disappearance of D.B. Cooper after a midair hijacking
• The Black Dahlia murder
• The Lindbergh kidnapping
• The Lizzie Borden case

Rather than offering definitive answers, Anthrax to Zodiac presents a disciplined examination of each case, separating what is known from what is assumed and showing how uncertainty persists—even after years of investigation.

Written by a veteran private investigator and award-winning author, the book balances professional skepticism with an accessible voice, approaching notorious cases with clarity, restraint, and the occasional wry observation—without losing sight of the human cost behind the crimes.

If you’re interested in how investigations unfold, why certainty remains elusive, and what the evidence supports—and doesn’t, Anthrax to Zodiac invites you to examine the record and draw your own conclusions.
