Kowalski, 25, of the 500 block of North Third Avenue, ran two red lights before crashing into the victims' vehicle at 108 miles per hour on March 7 at Rand and Mount Prospect roads. Police also said a blood sample revealed the presence of a controlled substance, ketamine, in his blood.
The Cook County state's attorney's office approved three counts of reckless homicide, three counts of aggravated driving under the influence of drugs and one count of possession of a controlled substance, police said in a news release.
