A 26-year-old Davenport man is charged with murdering his young son. Jeramy Essary’s been in jail for the past two months, ever since the death of his 16-month-old son, Niqolus, but the murder charges were just filed yesterday. Cops say just three days before the child’s death, Essary grabbed the boy by the back of his neck and slammed his head into an entertainment center, leaving a huge bruise on the child’s forehead. An autopsy concluded Niqolus was strangled. Essary, who is a self-employed cook, also is accused of hitting his wife, a neighbor and a cop the day he was arrested. Essary did prison time eight years ago after he admitted he broke his three-week-old daughter’s leg.
