They said at a news conference earlier today that two of them were his half brothers. He was headed to the other sibling’s house to kill him/her when they caught him.
Not all reading this may have noted an earlier 2024 news story where a transgendered kid killed this parents in Washington, utah (a suburb of St George). I think there was one sibling in the house who either escaped or was not targeted, don’t recall. That perp was also captured without exchanging fire with police. They were closer to 21 than 15.
You wonder (inclding Nashville) what the total death toll is from this rage). The utah perp specifically said their motivation was anger over parent’s non-acceptance of their gender change.
