Derrion Albert

Chicago police have asked the public for help to find three more teens believed connected to the fatal beating of Derrion Albert.

“We need the public’s help, your help,” Chicago Police Superintendent Jody Weis told reporters.

With four teens already arrested and charged with first-degree murder in the killing, “we are continuing to look for three additional people in connection with Derrion’s murder,” Weis said.

The U.S. Secret Service has been asked to enhance the video of the beating so they can be identified.

“The culture of ‘no-snitch’ is unacceptable,” he said. “A young man with a promising future lost his life to senseless violence, yet few have come forward.”

Weis said that they are also considering charging people who fought, but did not come into contact with Albert.

Albert was a bystander who was killed in the middle of a street fight last Thursday.
