This episode has very close similarities to the famous kidnapping case in Austria from 2006 that caused global media interest. The victim Natascha Kampusch was kidnapped in 1998 at the age of 10 and was able to escape after 8 years from her kidnapper who allegedly committed suicide shortly after.
Vanessa Marano (Holly Wheeler) was also in "Grey's Anatomy" spin-off show "Private Practice" playing the role of Casey.
Every episode of the show is named after a famous song. "The Girl with No Name" is a song by The Byrds.
