When Kim Flint’s SUV is found abandoned on a Rusk County, Texas, bridge after a one-car accident, her family and law enforcement are mystified as to what happened to the 57-year-old wife and mother. Kim, who suffered from various medical conditions, had given up driving months before. At home, investigators find the house unlocked and her purse and cell phone inside. Extensive searches have turned up no trace of Kim, who appears to have vanished into thin air.
