A Chicago police officer processing a burglary scene and another person were fatally shot Friday afternoon, police said.
The officer, an evidence technician, died at 2:30 p.m., one hour after the shootings, said Police Superintendent Jody Weis. Another man also died, Weis said, adding there was no information on a motive.
"The thought that someone can shoot and kill a police officer is unacceptable," Weis said. "We shall squeeze that neighborhood and we will find who did this."
The gunman is described as a black male wearing a gray thermal shirt, a blue vest and a gray skull cap, according to CNN affiliate WLS.
