'We are devastated by the loss of our father, Leo Belogur, under such horrific circumstances. He immigrated to this country in the late 1980s and worked tirelessly to provide for his family. It is a tragedy that someone can have so little regard for human life as to hit a human being in a crosswalk and just keep driving. Leo was a wonderful father to 3 kids and a grandfather to 7 children. He will be incredibly missed," the family said in the statement.
Belogur was a Ukrainian immigrant, grandfather and retired engineer. He had lived in an apartment near where the crash occurred. His walks were part of his regular routine.
The Major Crash Assistance Team is assisting Morton Grove police in the ongoing investigation.
Police have not provided the description of any vehicle suspected of being involved in the crash, however, the vehicle involved is believed to have significant windshield or front-end damage.
