What is a summary of the book Bogeyman: He Was Every Parent's Nightmare by Steve Jackson?

"Bogeyman: He Was Every Parent's Nightmare" by Steve Jackson describes Texas law enforcement's attempts to find and persecute serial child murderer David Elliot Penton. Penton frequented low-income and majority non-white neighborhoods to find young girls to rape and murder, believing that law enforcement would be less likely to pursue justice for those children. He kidnapped children by pulling them into his car in broad daylight, or by sneaking into their homes at night to take them from their beds. The kidnappings began in 1985, and ended up as cold cases for over a decade.
In 1996, police detective Gary Sweet along with a team of officers began working on the cases again, determined to find the murderer. It took several more years before the police team was able to find enough evidence to indict Penton, but in 2003 they found him imprisoned for the murder of a young girl in Ohio and pressed charges against him for three other murders. Penton pleaded guilty in 2005 to the murder of the three young girls and was sentenced to life in prison.
