Tinley Park Shootings

If you haven't read the news, I recommend you take a look before proceeding.
Tinley Park is actually very close to where I live, about a 10 minute drive. The place is usually quiet and peaceful, I've been to it many times and actually have a few friends who live there as well as job associates.
Now, Lane Bryant is a quiet store, especially in the mornings. Its clothes are generally aimed at women, usually mature. Thing is, the perpetrator picked the right time and right spot to do this crime.
Apparently it was a "robbery gone bad." I disagree, because you don't go to a store, have 5 women line up Nazi execution-style, shoot them in the neck, then leave without taking any money.
Which leaves me to question his purpose. This rant is not aimed at perpetrators in general, but perpetrators without any purpose and without necessity to kill but they do it anyways. Why would one just walk into a store, murder a few people, then walk out with no one knowing until an hour later?
It is a really pointless thing, which makes me question: perhaps he did it for himself, or maybe he has something race-involved (but two of the women were African American, so that rules it out.) Cult initiation? Revenge? Or just for the hell of it?
I can't really find a solution.
He has not been found yet, but there was one survivor who described him to the police.
