Reader's　Digest ３・４月合併号の記事 "Operation: Find Avery " からの引用です。

Witherspoon's case of a missing pet turned into something sinister when, 24 hours after the dognapping, her cellphone buzzed. In menacing texts laced with profanity and misspellings, someone claimed to have Avery and sent a video of the pup in a cage. The conversation was punctuated with a threat to kill the dog and a demand for ransom: "Y'all not getting y'all dog back Y'all paying 1200 no funny's!!'
