Tina McQuaig was a 27- year-old wife and mother. On the evening of March 15, 2000, after work at the hospital, she called her babysitter to say she’s stopping at the grocery store on her way home. That was the last anyone heard from McQuaig. When her car was found four days later, her keys and purse were gone, as if she parked and walked away. As authorities probe McQuaid’s life, they discovered secrets that stun her husband and family.
