What a sad story! I am something of a true crime junkie (guilty pleasure) and was grateful to receive a copy of A Convenient Suspect from Chicago Review Press and NetGalley in exchange for this honest review. 
 As a true crime junkie and a podcast aficionado (and don't even get me started on my favorite true crime podcasts!), I have increasingly become aware of the many outrageous examples of prosecutorial misconduct and evidence tampering that have been brought to light by journalists, investigators, and just plain folks looking for truth and justice. Well, this book is another example of what seems to a case of settling on a suspect then tailoring the actions of the police and prosecutors to fit. 
 Here's the situation: Shortly before Christmas in 1994, a young mother named Joann Katrinak and her three-month-old son, Alex, disappeared from their home in Catasauqua, Pennsylvania. Their bodies weren't found for four months, when they were found in nearby woods. The police investigated for three years before arresting another young mother named Patricia Rorrer. Although Patricia was the ex-girlfriend of Joann's husband, she had never met either Joann or Alex. 
 The prosecution's theory was that Patricia brutally beat Joann, shot her and left her and her baby for dead in the woods, and Patricia Rorrer was quickly tried, convicted, and sentenced to life in prison without parole. 
 Fast-forward to Rorrer filing for FBI records under the Freedom of Information Act, and finding a document stating that hairs that were looked at by the FBI did not have a hair root. This was the critical piece of evidence used at Rorrer's trial, and her attorney is working to re-examine what he sees as a totally flawed forensic investigation. 
 He is adamant that once state police started to focus on Rorrer as a potential suspect, they went to North Carolina where she was living and they obtained a sample of her hair to compare to the ones found at the scene. He asks a good question: "... whether the hairs that were actually tested were in fact hairs taken from the seatback or were they part of that general pile of hairs that were taken from Patricia Rorrer in North Carolina?" 
 In writing this book, Mal uses information that was not previously made public, gathered from more than 10,000 official documents, including Pennsylvania State Police reports, FBI Files, forensic lab results, and the 6,500-page trial transcript. 
 The case has been covered by the usual sources that have popularized true crimes, including People magazine, Dateline, and Investigation Discovery but none of them have the depth of this book. It was well done, and sufficiently provoked enough outrage in me to cause me to read further about this case. Yes, the deaths of Joann and Alex were very sad, but a thirst for resolution that results in a rushed conviction based on sloppy forensic work is not only sad, it's unjust. The subtitle wraps it up nicely: A double murder, a flawed investigation, and the railroading of an innocent woman. I'm giving this one 5 stars -- for its genre, it's OUTSTANDING.
