Hmmm....
Wonder if a search of their phones and/or gps on vehicles led them to this area ?
It appears that Lake Cornelius is to the right of I-77, if you are heading north whereas Lake Norman is to the left (I’m a Charlotte native that lives in Concord now and never knew there was a difference until now). That being said, the other end of her street (I’ve placed a red mark over her house at the bottom of this Google Earth map) has water frontage/wooded shoreline on Lake Cornelius.It seems the lake being searched in Cornelius is Lake Norman, it is quite large and short drive from parents' home
