ATGLEN—Schiffer Publishing and author Bruce E. Mowday have entered into an agreement to write and publish a book on the 1972 sniper slayings of Kennett Square policemen William Davis and Richard Posey.

“The murders of the two law enforcement officers were tragic for their families, Chester County law enforcement and the county and the country,” said Mowday. “The murders were significant in a national context. At the time, the killings of two law enforcement officers in a small town was unthinkable. The nation then realized violent anti-societal crimes could take place anywhere in the United States, if they occurred in Kennett Square.”

Earlier this year, Schiffer Senior Editor Robert Biondi discussed the project with Mowday. Biondi, who grew up in Kennett Square, said, “We were quite riveted to the case as it progressed. I recall the national media broadcast vans and how jam packed the memorial service was for the officers.”

Mowday, a West Chester author of more than 20 books, is in the process of conducting research and doing interviews. “I’m gaining access to an incredible amount of material,” Mowday said. “I’m hoping others with information will contact me.” Mowday’s email is mowday@mowday.com.

The murder investigation was also the catalyst for the formation of a group of elite Chester County law enforcement investigators – local, county, state and federal - and prosecuting attorneys. That band of peace officers worked together for almost a decade to imprison members of gangs of Chester County-based criminals, including the Johnston brothers and the Matherly-Madron family.

“The murders of William Davis and Richard Posey were on the minds of the investigators as they went about their dangerous jobs in the 1970s and early 1980s,” said Mowday, who covered the cases as a reporter for the Daily Local News of West Chester. “The book on the Davis and Posey murders will conclude a trilogy of my books on the criminal period of Chester County. I’ve previously written Jailing the Johnston Gang: Bringing Serial Murderers to Justice and Stealing Wyeth.
