When 26-year-old Erika Cirioni went missing New Year's Eve 2006, she left her family and friends distraught and desperate for answers. Who was she with that night? Was she still alive? And, if not, why might someone have wanted to kill her?

When children playing in the woods in Montville found Cirioni's remains in March 2012, one of those questions was answered, but the others remained. In today's episode of "Case Unsolved," you'll hear family and friends — including one who got a call from Cirioni the night she disappeared — talk about what they think happened to Cirioni and how her death still affects them.
