The Chicago Police Memorial Foundation is now offering $20,000 to anyone who helps identify those responsible for fatally shooting Officer Clifton Lewis during a convenience store robbery a week ago, according to the foundation.
"These donors join us in our grief for Officer Lewis and his family," said Philip Cline, the foundation's executive director. "They also share our desire to do whatever is necessary to identify the person or persons responsible for taking the life of a fine Chicago Police officer."
