January 2, 1999 was an average day in sleepy suburban Mesa Arizona when, as dusk was falling, 11 year-old Mikelle Biggs and her sister Kimber thought they heard the sound of an ice cream truck coming up the street as they were playing outside their house.\xa0\xa0Mikelle ran into the house and convinced her mother \u2013 who was just starting dinner, to give her some quarters so she and Kimber could buy a treat.\xa0 Racing back outside, Mikelle borrowed Kimber\u2019s brand new pink bicycle \u2013 which Kimber had just gotten for Christmas only 8 days prior.\xa0\xa0Seeing her sister riding up the street on her bike, Kimber decided to go back into the house to get a jacket.\xa0 It took her all of 90 seconds to return to the front yard where she would run to catch up with Mikelle.\xa0\xa0But instead of seeing her sister riding farther up the street, what Kimber saw instead was her empty bike, lying on its side in the middle of the street, pointed back in the direction of their house \u2013 the front wheel still spinning.\xa0\xa0In 90 seconds \u2013 Mikelle Biggs went from a bright, beautiful young girl riding to catch an ice cream truck in the fading winter light \u2013 to a memory.\xa0 She has never been seen again.\xa0\xa0While there is a likely culprit who has been identified \u2013 now in prison for a different, horrific crime - he has never been charged and has denied having anything to do with Mikelle\u2019s disappearance.\xa0\xa0In this moving episode, Melissa describes the police investigation, the family\u2019s exhausting quest for answers, the haunting image of that gleaming new pink bicycle lying still, its front wheel still turning from the impetus of Mikelle\u2019s force \u2013 and how all these years later, those 90 seconds live forever in the heart and soul of a little sister who wonders \u2013 what if she had not gone to get that jacket?
