Unraveling a twenty-five-year tale of multiple murder and medical deception, The Death of Innocents is a work of first-rate journalism told with the compelling narrative drive of a mystery novel. More than just a true-crime story, it is the stunning expose of spurious science that sent medical researchers in the wrong direction--and nearly allowed a murderer to go unpunished.

On July 28, 1971, a two-and-a-half-month-old baby named Noah Hoyt died in his trailer home in a rural hamlet of upstate New York. He was the fifth child of Waneta and Tim Hoyt to die suddenly in the space of seven years. People certainly talked, but Waneta spoke vaguely of "crib death," and over time the talk faded.

Nearly two decades later a district attorney in Syracuse, New York, was alerted to a landmark paper in the literature on Sudden Infant Death Syndrome--SIDS--that had been published in a prestigious medical journal back in 1972. Written by a prominent researcher at a Syracuse medical center, the article described a family in which five children had died suddenly without explanation. The D.A. was convinced that something about this account was very wrong. An intensive quest by a team of investigators came to a climax in the spring of 1995, in a dramatic multiple-murder trial that made headlines nationwide.

But this book is not only a vivid account of infanticide revealed; it is also a riveting medical detective story. That journal article had legitimized the deaths of the last two babies by theorizing a cause for the mystery of SIDS, suggesting it could be predicted and prevented, and fostering the presumption that SIDS runs in families. More than two decades of multimillion-dollar studies have failed to confirm any of these widely accepted premises. How all this happened--could have happened--is a compelling story of high-stakes medical research in action. And the enigma of familial SIDS has given rise to a special and terrible irony. There is today a maxim in forensic pathology: One unexplained infant death in a family is SIDS. Two is very suspicious. Three is homicide.
