Various motives, including greed and jealousy, have been advanced for the sudden, lethal violence which overtook Chester Comer in 1935. 

In retrospect, it seems that none of the suggested motivations adequately answer for the mayhem of a mind that went abruptly, brutally awry. 

Comer's first known victim was his ex-wife, Elizabeth, whose bullet-riddled body was discovered near Kansas City, Kansas, in the fall of 1935. Badly decomposed, the body would not be identified until December, by which time Comer had already murdered his second wife, Lucille, dumping her nude body in the countryside near Edmond, Oklahoma. 

From Edmond, Comer drove southwest to Shawnee, abducting and murdering Ray Evans, a local civic leader, stripping his victim before dumping the corpse in a field outside of town. Veering westward again, Comer picked off his last two victims -- farmer L.A. Simpson and his son Warren, fourteen -- leaving their bodies fully clothed after he gunned them down, execution-style, in a rural pasture. Comer was still driving Simpson's car when Marshal Oscar Morgan stopped him in Blanchard. Shots were exchanged, and Comer was fatally wounded. 

Dying, he confessed to "doing away" with Evans and the Simpsons, but advanced no explanation for his crimes.
