Query: 5 Star Story of a Crazy Killer Cop

An interesting, well written & researched tale of a Houston Sheriff's Deputy who never should have been allowed a badge. This story occurred in the Spring/Klein/North Houston-1960 area. The story highlights the issues surrounding the problems with the many layers of police departments in the city & county, & their inability to successfully share information. It is frightening how easy it was for this crazy officer to accomplish this murder. Considering the number of police officers in Houston & Harris County, it makes you wonder how many other Sociopaths are in the departments. Living in the area that this crime occurred, teaching in the school district McGowan's son attended, & having patronized the described businesses, made the book even more interesting. Casey made this story a "Can't put down" read, excellent!
