Just cuz I'm bored right now and for no other reason, a Muslim fighting a Jihad is called a Mujahideen, Arabic for Holy Warrior. There are various spellings for Arabic words and names using the english alphabet, so you will see a variety of spellings for the same thing. It's problematic to convert from a non-english alphablet to english regardless of the language. It's so bad for the various Chinese dialects and caligraphies that most DoD and DoS agencies use a numberic representation for names.
Nobody really knows what his motive was. Cover to kill his Ex, writings while in prison before trial rambled on about Jihad, he made comments about kidnapping kids(?), bla bla bla... He was a sociopath.
Wood chipper...
