Ok, I found her on the Nation's Missing Children and Adults website in the Center for Missing Adults section:
http://www.missingadults.org/gallery/index.htm
It won't let me put a link directly to her page. Anyway, click on "Adult" on the tabs there. People are listed alpabetically. Click on letter C and it will bring up all the missing adults with the letter C for their last name. Heather is in the third row down.
