A Berwick woman is in the Columbia County lock-up on attempted homicide and aggravated assault charges after failing to post $300-thousand bail. Berwick Police say 40-year-old Sharon Blalock tried to run down her one-time fiance, Michael Sink, with her car Sunday evening. Blalock’s car hit the bicycle Sink was riding and then her vehicle slammed into Bob’s Sub Shop at Second and Mulberry in Berwick. Sink refused medical treatment. Cops say the pair was seen arguing before the crash and there was no sign that Blalock tried to slow down before impact.
