Dead ball technical- High School rules questioin

[stewcall]

happened during a women's NCAA basketball playoff, but my question is more of a high school rules question.
A1 is about to throw the ball in from the sidelines. The official has not handed the ball to A1 (dead ball). player A2 makes a cut to the ball when she is blocked by B2. The official administering the throw- in, raises his fist for a foul. A2 continues and stumbles and lands a forearm into player B3 jaw (not intentional but a solid hit). The crew huddles and calls a technical (1) on B2 and ignores the second foul. B2 shoots 2 free throws and gets the ball at half court. I understand a dead ball technical, but I don't think the second foul (technical) should have been ignored. If it was called would it be simultaneous technical or each administered separately.
