A Richfield man is charged with first-degree assault for allegedly almost killing his girlfriend, who suffered a six-inch long laceration to her neck nearly four inches deep. 29-year-old Thomas Boyd was hospitalized after the Monday morning attack because authorities say he appeared to be overdosing and they administered Narcan to counteract the suspected opioid in his system. Police recovered a butcher knife, wrapped in a red jacket, from the kitchen counter. Boyd’s bond was set at 50 thousand dollars with conditions.
