Missouri Attorney General Andrew Bailey filed additional charges Wednesday against a man accused of shooting two Hermann police officers in March. One of the officers died as a result of the shooting. Bailey charged 35-year-old Kenneth Lee Simpson of St. Louis County with additional felonies including unlawful possession of a firearm, unlawful possession of an illegal weapon, possession of a controlled substance, and resisting felony arrest. Simpson was previously charged with first-degree murder, two counts of armed criminal action, first-degree assault on a special victim, and unlawful possession of a firearm. He pleaded not guilty to those charges. The charges allege that after 9 p.m. on March 12th, Simpson shot the two officers at Casey’s convenience store in Hermann, after the officers arrived to arrest Simpson on multiple outstanding warrants. Simpson then fled the scene to a home nearby, where a 14-hour standoff took place. Coincidentally, an American Red Cross blood drive to honor the police officers will be held this afternoon from 12 to 6 o’clock at St. George High School in Hermann.
