The clown that wrote this article provides no context, no date of the shooting, etc. His lack of info makes it reasonable to presume she was shot by another Muslim. Or perhaps a rabbit. Or a two year old who was resisting potty training. When essentially no information if offered, other than his 68 yr old relative got shot, then one may presume anything and every thing, as there is no information available to bring facts into play.
He forgets the fact that an armed society is a more polite and less violent society.
If you follow some links in the comments, you discover this “hate crime” was actually a negligent discharge. Some moron shot himself in the hand and her across the street.
Other stories say that the shooting was accidental and that the shooter accidentally discharged the weapon striking himself in the hand and the bullet then struck the woman who just was in the wrong place at the wrong time.

Google search shows it was an accidental discharge that injured the carrier as well.
