In the town of Windsor Locks, Connecticut, a police officer is accused of being responsible for a car crash that took the life of 15 year-old Henry Dang, who was riding his bicycle home from a friend’s house on Oct. 29. Some witnesses say Officer Michael Koistenen, who was off-duty, was drinking at a tailgate party prior to the accident. Windsor Locks police did not take a blood sample from Koistinen or administer a Breathalyzer test. Windsor Locks Police Chief John Suchocki told The Courant he would not comment on whether Sgt. Robert Koistinen, Michael’s father, was in charge of the crash scene. The boy’s family had criticized the department for allowing the elder Koistinen to be at the scene. The sources said investigators are developing a timeline of Michael Koistinen’s whereabouts in the hours before his car hit Henry Dang. Koistinen is on paid administrative leave.
