Some articles have said she called her stepfather, others have said her father. In some ways, it doesn't really matter-- I'm sure whoever he was, he was shocked and told her to call 911 immediately. He may have also called 911 himself. I'm sure something like that would have happened whether he was the bio dad of both girls, the bio dad of neither girl, or the bio dad of only the younger girl. But the family dynamics may have been affected depending on whether he was a stepfather or bio dad.Oh, ok, I knew that, but I got confused and was thinking of her stepfather as someone who lived somewhere else, and the parents who were out that day as her mother and father, so that changes my whole understanding, thank you.
So I can't imagine what she could possibly have said to stepdad to inform him she had just stabbed his daughter to death, but whatever it was, I assume he ordered her to call 911 and sped home, probably while also calling 911 himself on the way. Which could mean they all arrived near the same time. What a terrible day.
There also seems to be some reporting confusion over who posted the flushing note. Most sources SEEM to say it was the younger girl. If so, I'm pretty sure a 7-year old's note didn't say something like "Please be courteous and remember to flush the toilet when you are through. Thank you!" I expect she used more "colorful" language and may have aimed the note at her sister specifically. Not that that's an excuse for the reaction from the 13-year old but it might PARTLY explain it.
