Incredibly upsetting story. After I was threatened the first time, I filmed every single pickup with my kids on a succession of phones. I still take my phone out when I pick up my kids and keep it handy when they are being picked up. Just as in my case, it was a routine pickup, and just as in my case, the aggresor invented a story after the fact. I hope she goes to prison for a long time, and there's no way the daughter should be allowed anything other than supervised custody after this.
Yikes. Earlier I saw a headline along the lines of "man records own shooting on phone" and assumed it was a suicide story. (I didn't click through then.) Worrying about getting shot while picking up your kids? *shudder*
