Three murders so far afaik:

first the landlord by a group on the west coast, he had a gun and was threatening all of these trans kids with eviction

then on the east coast one or more parent(s) of one of the zizians, this person was uninvolved with the first murder and allegedly killed their own parent(s)

and a third group unrelated to the previous two incidents, who were near the Canadian border in the NE, pulled over by border patrol, and ended up killing the guard because one of these zizians was a foreigner on expired tourist visa and I guess they panicked

The scenarios have logical and to me obviously unrelated motives, and didn't have much overlap of involved parties. Seems like a bunch of traumatized trans kids who were reacting poorly to what they truly felt were life and death situations, none of which have any clear connection to their philosophical or ideological fixations
