Robert Bobby E Crimo III

The police released his photos. He is a rapper and happen to have symbols that are said to be white supremacist on his desk. (Picture 2)

He goes by the alias, "Awake, The Rapper."

What's more disturbing is his works, one of which is called Skinwalker. He communicated openly with this video that he is planning something like this. He posted this chilling and violent video eight months before the attack.

Funnily enough, his father is a Trump supporter who defended gun rights. Says a lot about the upbringing.

People are suspecting that his main target was Jewish people who are in great population in the highland park.
