Officers and volunteers from the CAPS office walked Bailey's South Side neighborhood Saturday passing out fliers geared at convincing people to share information pertaining to the officer's fatal shooting.
The reward money in the case is now up to $100,000.
"Sometimes they brag, and other people pick up, and they hear things. And those are the kind of things we want reported. We know that the reward money is an incentive to loosen lips," said 6th Ward Ald. Freddrenna Lyle.
Mayor Daley is urging anyone with information on Bailey's death to contact the police.
"You just cannot stay silent. It's a nickname, it's a name, it's an address, it's a car, you know, all the little things that add up in an investigation," Daley said.
Officer Bailey had just finished his overnight shift providing security at the mayor's house when he was shot last Sunday morning.
The 20-year veteran of the department was just weeks from retirement and had bought himself a new car to celebrate.
Police say the person or persons who shot him tried to steal his car.
