Zero Day shooting In-Depth Timeline of Events
Witnesses spot Kriegmanβs gray 1991 Pontiac Grand Am. It is presumed that Calvin Gabriel and Andre Kriegman are both in the car at this time. They turn off a video camera they have brought with them. Their whereabouts are not known for certain for the next hour and thirteen minutes.
Kriegman and Gabriel turn on their video camera, retrieve their weapons from the trunk. They spend approximately 5 minutes loading their weapons and proceed towards the west entrance of Iroquois High School.
10:02:10 AM - 10:02:17 AM
As Kriegman and Gabriel approach the west entrance, they encounter Melissa Baker, Jason Zuffoletti, and Tony DeFasio, who are sitting to the left of the entrance. Kriegman and Gabriel fire upon the students. All three are hit; Zuffoletti and Baker are killed instantly, and DeFasio is able to flee. Robert Straitharn comes through the main entrance and is wounded by Kriegman. He turns around and runs back into the school. James Regent, Michael Oster, Jennifer DiCaprio, Alison Stewart, and Kristin Powers are also outside, around the corner to the left of the main entrance, in a courtyard with walls on three sides. When the shooting starts, they make their way to the wall farthest from the main entrance and run. After firing at Straitharn, Kriegman and Gabriel turn their attention to the group coming out of the cul-de-sac. Kriegman wounds Oster and Dicaprio, and Powers is hit by Gabriel in the leg. Kriegman and Gabriel pause to reload, and Regent and Stewart take this opportunity to assist Powers. Kriegman and Gabriel lose interest in this group, and opt to enter the school.

Kriegman and Gabriel enter the school and encounter Resource Officer Leon Stetz. Witnesses observe Stetz issue a warning and draw his weapon. Kriegman and Gabriel and Stetz exchange fire. Stetz fires three rounds and is hit three times by Gabriel. Stetz dies of his wounds before aid can arrive. Stetzβs revolver is later found sabotaged, presumably by Kriegman or Gabriel; a safety pin is inserted in the breech. It is not clear when this was done.

Students in the west of the library observe Kriegman and Gabriel through the libraryβs east entrance and start to rush towards the main entrance. Others in the main entrance of the library follow them. The students at the front of the crowd see Kriegman and Gabriel approaching and change direction followed by the rest of the students. Kriegman and Gabriel wait until they are in through the doors and open fire. Victoria Evers and Omar Walters are hit; Evers dies of her wounds before aid can arrive. Omar, who has called 911 shortly before Kriegman and Gabriel arrive, is able to move into the reference area with other fleeing students. The larger group of students escapes through the west entrance. Kriegman picks up the cellular phone that Walters used to call 911. The phone will remain with Kriegman and continue to transmit until the SWAT team arrives.
10:02:45 AM - 10:03:05 AM
A group of approximately thirty students moves east to the reference area while Kriegman and Gabriel are occupied in the main area. Walters cannot keep up with the rest of the group and sits down. At this point the group splits up again. One group moves upstairs to a study room, while the second group makes it way to an emergency exit. Worried that the alarm on the emergency exit might draw Kriegman and Gabriel, they force a window open and jump down 4 feet to escape.
10:03:20 AM - 10:03:45 AM
Kriegman and Gabriel follow the fleeing students through the reference area and stop to taunt Walters. They then proceed upstairs to the study area and encounter Sarah Pilar, Brent Pearlman, Chelsea Castro, Megan Donner, Carmine DiBano, Chris Thomas, David Foster, Derek Sutter, Tina Vincent, and Greg Krupa. They are hiding under tables and behind couches.

Officers Leah Halstrom and Frank Vincenzi arrive on the scene. Officer Halstrom drives around to the west while Officer Vincenzi stays at the east entrance.
10:08:11 AM - 10:12:25 AM
Kriegman and Gabriel move out of the library and head towards the cafeteria. As the two gunman walk down the hall, their attention is drawn to the kitchen serving area, which joins the hall to the cafeteria. A group of 10 students are hiding in the kitchen and the serving area, out of sight from the door. Both Kriegman and Gabriel throw one lit pipe bomb each into the serving area and continue on towards the Cafeteria. The pipe bombs detonate while the some of the students in the serving area are trying to move into the rear of the kitchen. Lynn Knoblock, Christian Kluge, and Stanley Forster all suffer burns; one of the bombs bursts completely, hitting Kluge and Forster with shrapnel. The other pipe bomb does not splinter, but the force of the exploding gunpowder sends both end-caps in opposite directions at high velocity. Lynn Knoblock is hit with an end cap, and receives a broken shoulder. Naomi Kleber is hiding in a thick metal storage cabinet 3 feet from the pipe bomb that bursts; she receives no serious injuries.
Kriegman and Gabriel move to the east cafeteria where they attempt to ignite a homemade bomb. After a first failure, they destroy a cash register with second pipe bomb. Kriegman fires on a vending machine. This attracts Officer Halstromβs attention; she stops her cruiser, disembarks and tries to find the source of the fire. Gabriel spots her cruiser and fires six rounds towards Officer Halstromβs position. Three of these rounds hit Officer Halstromβs cruiser. Officer Halstrom returns fire through the window broken by Gabrielβs fire. Kriegman and Gabriel move back into the hall, towards the library. They each fire on library computers in the west wing of the library.
Kriegman and Gabriel return to the study area, where they observe the arrival of state police, county police, SWAT, and paramedic units.
Kriegman points his empty revolver at his head and dry-fires it repeatedly.
Two SWAT teams form up to enter the school. One team enters through the west entrance, the other moves to the main entrance on the east. The east team led by Sergeant Leonard Krantz, is directed to the study area by Foster.
After a short discussion, Kriegman and Gabriel kneel down, point their weapons at their head, and fire. Both die instantly.
Sergeant Krantzβs team reaches the study area and find Sutter and Vincent. Even though it is not clear that Kriegman and Gabriel are the only assailants, elements of the state and county police evacuate Sutter and Vincent under cover of Sergeant Krantzβs SWAT team.
Sergeant Krantzβs team resumes it sweep, and in conjunction with Sergeant Brian Lomaxβs team, clears the school with the exception of the east cafeteria, where an unexploded pipe bomb is found.
The county bomb squad neutralizes the pipe bomb.
