UPDATE on the murder of New Jersey teens

It seems a 6th arrest has been made in the execution of the New Jersey students.

Fox News has the only coverage I've found. Kudos to FNC.
I am deducing from the report,

"About 10 officers from the Newark police department, Essex County Prosecutor's office and Immigration and Customs Enforcement made the arrest at about 3 a.m., prosecutors said."

that this guy and his brother are yet more illegal aliens connected to these murders.

Are any of the 6 here legally?

Why is there no uproar over this?

Wake up people!!! Demand your laws be enforced!!!
