1) This CO was either under the influence of drugs or alcohol or both; and that part of the story was ignored by the police in typical fashion. After all; CO's and LEO's are a pretty darn close knit group.
2) This CO was driving at a high rate of speed and lost control of his vehicle. As the public knows; the police look the other way for speeding offenses, reckless driving; DUI etc when it is being committed by a fellow officer or a CO.
3) This CO was involved in a drug dealing operation at the jail where he works; and he had fell out of favor with his fellow accomplices; some of which are high ranking jail inmates and some of which are fellow CO's.
4) This CO became aware of an ungoing drug dealing operation at the jail involving fellow CO's as well as high ranking jail inmates and either he wsn't going to stay quite about it or he wanted a share of the action, and he was eliminated via of a motor vehicle crash.
Again, the public is well aware of the goings on in it's prison systems. This suicide tale just doesn't add up.
