A jury has found a former Windsor Locks police sergeant not guilty of hindering an investigation involving his son.
Robert Koistinen is accused of interfering in a deadly crash involving his son, Michael, also a former Windsor Lock police officer.
In 2010, Michael Koistinen, off-duty at the time, hit and killed 15-year-old Henry Dang, who was riding his bike.
Michael Koistinen pleaded no contest to second-degree manslaughter and tampering with physical evidence. He is serving five years in jail.
A Connecticut State Police investigation found Michael Koistinen was speeding and drunk that night, but no sobriety test was ever given.
The jury reached its decision Wednesday after six days of testimony.
Robert Koistinen chose not to speak to the media after trial.
However, his lawyer said he was made the scapegoat in the case and believes mistakes were made in the investigation that were not Robert Koistinen's fault.
"There was not any substantial evidence that I would point to, to convict this man," said juror Nancy Senatra.
Henry's family was seated in the front row of the courtroom Wednesday morning.
Both Koistinens have been fired from the department. Robert Koistinen plans to try and get his job back.
