20 + 22; I'd been using 20+ earlier in post but I did see folks start to quote one of the girls was ~28 here and elsewhere and should have confirmed before repeating it. Ironically, the only article I've seen so far quoting their exact names and ages is this Canadian media report:

https://globalnews.ca/news/7786124/makhia-bryant-fatal-shooting/

But other than that, the sequence of events as I understand it is from WaPo and CNN reporting linked elsewhere in this post which incl quotes from her 911 call and eyewitness accounts.

And no, I don't share your loose definition of "home" as it applies to those girls. Ma'Khia was a minor and was in her foster home, period. Those other girls were just visiting. She was shot outside the home but they were all still on the property, which has legal implications if we take into acct Ohio's Stand Your Ground law (which I linked descriptions of above) and its provisions about whether the self-defense is occuring at a person's home.

I acknowledged in an earlier post that the reason for this particular fight is petty, but imho that's just a testament to the immaturity of the girls involved. It doesn't diminish how viciously they were fighting. Additionally, all of those fighting are or were in foster care "for a reason" at some point, so whatever ad hominem you're trying to set up to demonize Ma'Khia don't forget to do it for the other young women too.
