For family and friends of Michele Harris, the last 8½ years have been a blur of investigations, trials and jury deliberations. To the outside world, Michele and her husband, Calvin Harris, had a perfect life - they were young, attractive and successful with a beautiful family and a home in a picturesque upstate New York town.  But Michele's disappearance in the early morning hours of Sept. 12, 2001, revealed a much darker story. With much of New York State Police and canine forces diverted to New York City in response to the 9/11 terrorist attacks, local investigators were slowed by the limited resources available to them. Was this the perfect time for murder?  

Michele's disappearance remained shrouded in mystery until state police discovered tiny drops of blood in the Harris home. After four years, with no body or murder weapon, investigators felt they had enough circumstantial evidence and arrested Calvin Harris for Michele's murder.  In May 2007, the case went to trial and Harris was convicted of second-degree murder. As he awaited sentencing, a new witness emerged, and Harris' conviction was overturned and a new trial was set for 2009.

In the end, a second trial would reach the same guilty verdict, but as Calvin Harris continues to maintain his innocence, he is now fighting for a third trial. Meanwhile, authorities have not given up the search for Michele's body.
