"Untill a child dies, it doesn't seem to get much attention," Harris said.
Trumbull in the Gage Park neighborhood. It was the day after Thanksgiving as well as his birthday.
Chicago police say his mother Crystal Valdez watched and did nothing as her boyfriend Cesar Ruiz allegedly killed her son. Now, they both face charges of first degree murder.
Christopher's death in November, however, wasn't his family's first encouter with DCFS.
"They didn't do what they should have done when you have a child that's abused," Harris said about DCFS. "They should have stepped in, should have made more visits to the home, but also to the mother."
Back in July, Christopher's mother took him to the emergency room with a black eye and bruises over his body. Doctors didn't buy her story that he had fallen, so they reported her to DCFS and an investigation was launched. A month later, DCFS dismissed the case even though the mother had reportedly admitted she had beaten the boy and admitted she had anger issues.
According to documents obtained by the Chicago Tribune, DCFS apparently closed the investigation sooner than normal, ignored key elements of the police investigation and accepted the mother's initial claim that Christopher hurt himself on his own. A few months later the boy was murdered.
Robert Harris says the Valdez case represents a pattern of neglect within DCFS.
"I'm not saying these peolpe, DCFS is a cold hearted agency -- it's not -- but I think there is a pattern and reluctance to really get in there and do the hard work that needs to be done," Harris said.
While DCFS declined an interview with WGN-TV, DCFS spokesman Kendall Marlowe told the Chicago Tribune: "We need to handle each individual investigation properly and take action to protect every child who is in harm's way...At the same time, we cannot repeat the mistakes of the past and remove children from their families indiscriminately."
