Officers canvas Chicago neighborhood for clues in shooting of fellow officer.
Chicago police Wednesday said they're following several leads but still have not made any arrests into last weeks shooting death of an off-duty Chicago police officer.
"It is unacceptable," said Supt. Garry McCarthy, frustrated with the code of silence officials say is prevalent on the streets. "Here we are risking our lives trying to prevent other people from getting killed, and these are the instruments," he said, pointing to a cache of weapons collected on New Year's Eve.
Officer Clifton Lewis was working his part time job at the M&M Quick Foods nearly a week ago when two masked men walked in to rob the place.
Lewis was shot in the head almost immediately.
Lewis' brothers in blue canvassed the neighborhood on Wednesday, going door-to-door with fliers and a personal appeal to residents for information.
"If I heard something, seen something, I would surely tell it as quick and fast as I could," said resident Nicki Veal.
Meanwhile, the pot of reward money offered for information that leads to the arrest and conviction of Lewis' killers grows.
It's now up to $33,000, with $20,000 coming from the Chicago Police Memorial Foundation, $11,000 from the Fraternal Order of Police and another $2,000 from a group of pastors.
