Michael Colon, 16, was shot on Sept. 3, while walking his dog.
Chicago police still don't have any suspects.

"We've raised the reward because these murderers do not deserve to be walking the streets," Colon's sister Joanna said.
Police said a white SUV was seen in the area just before shots were fired. The car reportedly sped away right after the shooting.
