The article mentions that this same woman's 18 year-old son -- having a different last name -- was killed by his selected victim using the assailant's own knife.
So, this woman has a kid (last name different from her own), he grows up, engages in gang violence and gets killed during an ambush/assault by the person he's attacking.
Now this woman has another kid, under two years old, whose father lives "across the street," and he is murdered by some animal who has no problem shooting a baby in the face to make his "point."
A) The animal needs to be put down. Any redemption he might seek, he can pursue in whatever afterlife he has coming.
B) This woman leads a seriously weird life. I'm going to trudge out here toward the thin end of the limb and hazard a conjecture that she has some kind of associations going on that cause her to rub elbows with odd people, possibly criminal and violent people. It is agreed the limb is thin here.
C) The animal needs to be put down. Problem is, his ID is made by a woman who was under horrific stress, and therefore you need rock solid forensics to anchor that ID. But once it's rock solid, the animal needs to be put down. Possibly putting him in GenPop and spreading the word, "shot baby in face, unprovoked," would be enough.
D) The animal needs to be put down.
