Thanks to Shergal's sleuthing skills, I learned about a book written by former FBI agent Al Garber, "Striving to Be the Best: A Memoir". Mr. Garber was the FBI Agent in Charge in St. Joseph immediately following Jacob's abduction. The following are tidbits of info from the pages related to Jacob's abduction and the early days of the investigation.
* Jerry Wetterling's calm demeanor led some people to suspect he may have had some involvement or knowledge of the kidnapping. However, he was checked out, including a lie detector test with no indication of deception. Jerry's behavior had been consistent his whole adult life - he was quickly cleared as a suspect.
* Suspects began to develop immediately. A prison inmate at Stillwater told another inmate that he cad kidnapped Jacob. A recording device was installed in the prisoner's cell and he was recorded talking about Jacob's kidnapping. An undercover agent was sent in. The suspect told the agent that he wanted to pay to have his car destroyed. The suspect's car was torn apart from bumper to bumper but no evidence was found. A search warrant served on the suspect's rural farmhouse and turned up nothing. Garber and other LE attempted to interview the suspect in prison but he was uncooperative.
* FBI investigators noted a strong possibility that Jacob's kidnapping case was related to Jared's 9 months prior. A suspect was identified and a car was found that was owned by the suspect at the time of Jared's abduction. Fibers found in the car were similar to fibers from Jared's coat. The man was arrested (I could be wrong, but I believe this is the 1st time we ever heard about someone being arrested in Jared's case?) and charged, but charges were later dropped when the man lawyered up.
* Most information that came in from psychics was recorded and acted on, because LE believed that a person may be passing on legitimate information without having to name a source.
Mr. Garber credits many family members, friends, and colleagues among those who helped guide his career and provide inspiration for the book. However, it is the inscription on the inside cover of the book that indicates where Mr. Garber's passion lies:
"This book is officially published on October 22, 2009, the 20th anniversary of the kidnapping of Jacob Wetterling"
