UNTIL PROVEN INNOCENT The prosecutor was no longer sure both murder defendants were guilty. So he asked his dad -- the real-life Kojak. A mother's dying, gasping call to 911: "My husband! My baby!" In her secluded ranch house, she'd been stabbed with a kitchen knife. Her husband, infant and elderly father-in-law had all been shot in the head, point-blank. For three years, police had two suspects under surveillance, then arrest. Both faced the death penalty. But prosecutor Brian Cavanagh began to doubt that the defendants were partners. So he consulted with his father, a retired NYPD cop whose reputation for savvy sleuthing had inspired the creation of one of the most beloved characters in television history. Now the question was: Could Dad help solve the case? THE UNSOLVED MURDER OF ADAM WALSH The famous missing child case of Adam Walsh, a 6-year-old last seen at a Sears in a shopping mall in Hollywood, Florida, in July 1981 was the worst nightmare imaginable. Two weeks later, a child's severed head was found and identified as Adam. No one has ever been arrested for the crime. For the most part, the case's narration has been told by the victims, Adam's parents Reve and John Walsh. However, there has been another voice, independent investigative journalist and author of five True Crime books about Florida, Arthur Jay Harris, who has continued to write about it for two decades, and has worked on it with ABC News, The Miami Herald, and others. The deeply-researched story he tells disputes almost everything that everyone in the public has been led to believe. IN BOOK ONE, Harris shows that the taker of Adam was most likely not the drifter Ottis Toole, as police now say, but rather the serial killer Jeffrey Dahmer, who was arrested ten years later with eleven severed heads in his apartment. Harris documented him by a police report living near Hollywood as a transient about when Adam disappeared. That report had him supposedly finding a dead body in an alley behind where he worked. The report referred to a meter and storage room steps away where Harris and ABC News found blood droplets rising up a wall next to a lumberman's axe and a sledgehammer. Was this Dahmer's doing? Further, Dahmer was identified by seven police witnesses who said they saw him at the mall with or near Adam when he was taken. One of those witnesses said he saw him throw Adam into a blue van and get away. Where Dahmer worked there was a blue van, easily and often taken for personal use, without permission. Early on, a blue getaway van was Hollywood's first, best clue. IN BOOK TWO, Harris shows that all the official files are incredibly missing the most customary documents that would prove the ID of the found child who was said to be Adam. Among the documents missing are the autopsy report, a forensic dental report (considering that the ID was strictly based on a tooth comparison), and Adam's dental chart and dental X-rays. An investigation by the Florida Department of Law Enforcement confirmed his finding. In fact, the ID was not only shoddy and inadequate but is overwhelmingly likely wrong. In Adam's last photo he was clearly missing both his top front teeth. A police crime scene photo, never before published, shows the found child had a mostly-in buck tooth -- a top left front tooth. Harris consulted a number of pediatric and forensic dental and medical examiner experts who confirmed the obvious: there wasn't enough time for Adam to have grown it in that far. All that would have been exposed at a court trial -- but more than 30 years after Adam's disappearance, there has never been one. Did police end the search for Adam too soon? Could Adam still be alive?
