Three people are dead and a police officer is recovering from a gunshot wound following a series of shootings Saturday night.
According to a news release from the Chicago Police Department, gang investigation unit officers were conducting surveillance in the 5800 block of North Winthrop as part of a narcotics-related homicide case when they noticed people running from a building.
Three people were discovered inside -- two dead and one critically wounded.
The suspects who fled the building were soon located by officers, but rammed into a marked squad car and fired shots, striking an officer in the leg, investigators say.
The chase continued with the suspects reportedly continuing to fire shots at the officers until police stopped the car and returned fire, shooting and killing one of the men.
The Cook County Medical Examiner's office identified the suspect as 37-year-old Arturo Ibarra, of 4521 S.Troy St. He was pronounced dead at 6:23 p.m. Saturday at Saint Francis Hospital in Evanston.
According to the Medical Examiner's Office, the two people found dead on the scene suffered stab wounds and remained unidentified as of Sunday morning.
The two others were taken into custody.
The shot police officer's name was not released, but officials say he is a 39 years old and a 12 year veteran of the force, currently assigned to the Gang Investigations Unit.
The officer's gun shot wound is not considered life-threatening.
