Was the child his son or some random kid? He looks like your typical wannabe Jihadist Id love to know his immigration status..one of Omar’s relatives?
With a name “Emmanuel” he’s not a “jihadist” unless he has a convert name, as yet unknown. Middle name “deShawn” sounds like like a typical native born American inner city name. Drugs, or booze, or gang initiation, maybe. Mental illness or some twisted reason to hate the mother if it turns out he knows her, or if she’s an immigrant it could even be a case of hatred of immigrants. We’ll just have to wait and see why.
Random kid according to this https://www.twincities.com/2019/04/12/mall-of-america-boy-child-balcony-thrown-or-pushed/
