On Sept. 2 at 5:20 a.m., John Costulas of Chicago was walking east bound in the 500 block of Howard Street in Evanston, on his way to work. Evanston Police have now determined that as Mr. Costulas approached the Marathon Gas station, 555 Howard St., two assailants approached him, and without provocation, physically attacked him, said Commander Tom Guenther, public information officer of the Evanston Police Department. One of the assailants violently struck Mr. Costulas in the head, which caused him to fall to the ground, said the Commander. The assailants then looked out for possible witnesses, while one assailant went through Mr. Costulas’ pockets.
