In what may be the most significant clue toward solving the mystery of the hitchBOT, vlogger Jesse Wellen posted to his Snapchat what he says is surveillance video of the destruction of the robot.

The unknown assailant is seen wearing a jersey of former Eagles' QB Randall Cunningham.

See the video below.

hitchBOT traveled through Canada and Europe for a year but just made it two weeks in the U.S. before it was destroyed in Philly.
