Another thing, Hailey wore contact lenses because contact solutions were found in her bedroom. Most contact lenses need to be removed and soaked in cleaning solution before you go to sleep so assuming Hailey wore her lenses everyday, she would have to take the storage case & solution with her to planned sleepovers.
If SA returned to BDs after he left work at 6:10 am to kidnap and abduct Hailey, there is a good chance her contacts are still in the case. If Hailey left the house on her own accord on dec 28th intending to sleepover at a friends place and wore her contacts, she should have taken the case with her.
Snip
Friends and family said it was uncharacteristic for Hailey to leave the home without checking in with her mom.
Personal items like a toothbrush, hairbrush, contact solutions. New iPod, and jacket friends say she wouldnt leave home without were left behind. The weather was cold and Hailey was seen by Adkins leaving the home without a jacket.
