Crooks, of Bethel Park, Pa., squeezed off shots — one of which grazed Trump in the ear — at an outdoor rally in Butler, just outside Pittsburgh.

Sources said Crooks was planted on a roof of a manufacturing plant more than 130 yards away from the stage at Butler Farm Show grounds.

No information about Crooks’ background has been released as of this writing. By Sunday, his social media accounts (if they exist) will no doubt have been combed over.
