Incident & Biographic Details

Patrolman Irma C. Ruiz, Star #16823, aged 27 years, was an 11 year, 11 month, 4 day veteran of the Chicago Police Department. Ruiz graduated from the police academy on October 18, 1976 and was assigned to the Bureau of Investigative Services – Youth Division: Unit 074 – Area 4 Youth.

On September 22, 1988, at 10:15 a.m., Officer Ruiz and her partner, Patrolman Greg Jaglowski, were at Moses Montefiore School, 1300 South Ashland Avenue to pick up a student who had become a disciplinary problem when they were confronted by a mentally deranged gunman. The man had just shot four people, three fatally outside and at an auto parts store located across the street from the school. Officer Ruiz was shot and killed in the incident. Officer Jaglowski, despite being shot and seriously injured, managed to kill the assailant. Officers Ruiz and Jaglowski were credited with saving the lives of hundreds of young school children that day.

The incident began at 10:00 a.m. when Clemmie Henderson, age 40, A heavily armed gunman went into The Comet Auto Parts store at 1334 South Ashland Avenue and opened fire killing Robert Quinn, age 26, an employee and John Van Dyke, age 41, owner of the store. Henderson then left the store and walked to the Southeast corner of the Moses Montefiore School where he shot and killed Arthur Baker, age 34, a custodial worker at the school and wounded Laplose Chestnut, age 35, a city garbage collector. Henderson then entered the school through the front door located on Ashland Avenue where he observed Officers Ruiz and Jaglowski standing in front of the Guidance Counselors office a few yards into the school building. Henderson opened fire and Officer Ruiz was struck by a bullet that penetrated her heart and Officer Jaglowski was shot in the left thigh. Officer Jaglowski exited the school and went to his squad car to radio for help as Henderson went into an unoccupied room in the school to reload. Henderson then exited the school and was confronted by Officer Jaglowski on the sidewalk where both opened fire. Officer Jaglowski was shot again in the lower left leg and collapsed to the ground. As Office Jaglowski fell, he returned fire and struck Henderson in the upper abdomen and in the back. Henderson stumbled back into the school and collapsed a few feet from Officer Ruiz’s body. Officer Ruiz was transported to Cook County Hospital where she was pronounced dead on arrival. Henderson was also transported to Cook County Hospital where he died a few minutes after arriving. Officer Jaglowski was transported to Mount Sinai Hospital where he was treated, released and eventually recovered from his wounds.

It is unknown what set Henderson off that day, but at 9:30 p.m. Henderson had gone to the Chicago Lumber and Construction Company at 1238 South Ashland Avenue looking for a job as an armed security guard. He was told that the owners weren’t there, so Henderson went to a car wash in the same building and sat on a makeshift sofa with his eyes closed for 15 minutes and then left. It was then that he got up without saying a word and went to the auto parts store and began the shooting rampage. Henderson had a history of mental illness and in January, 1973 was taken to Chicago Reed Mental Health Facility by Cook County Jail Officials for evaluation. Henderson had served in the U.S. Army during Vietnam and was taking medication for depression.
