4.20.99 Timeline

4.20.99 Timeline

FYI this is a major work in progress and may take forever to be done. I will be adding things at all time points as I go.

12:35:00 - Dylan leaves Erics house

2:15:00 - Eric records the "Nixon Tape". The tape was found, still in the recorder, on the kitchen table of Erics house. On the tape Eric discusses the reasonings behind the attack that was to come and says the attack will happen less than 9 hours from now. Describing the day to come he says "It will be a day that will be remembered forever." Info from the 11k HERE. 

5:00:00 - Eric wakes up around this time, if he even slept at all. 

5:50:00 - Eric is scheduled to arrive at Nate Dykemans house to pick him up and drive to bowling class together at Belleview Lanes 

6:00:00 - As per their schedule Eric drives to KS (King Scoopers) and meets up with Dylan

6:30:00 - There is some speculation that Eric and Dylan may have driven to the bowling alley and sat in the parking lot for some time. The bowling teacher, Kristine Macauley, told JCSO that she thought she recalled seeing both Eric and Dylan in the parking lot at Belleview Lanes on the morning of 4.20.99. Another student in the class, Jennifer LaPlante, told investigators that she saw both Eric and Dylan in the parking lot that morning and that she said hi and they nodded at her. Seen HERE. I doubt that they were actually there on that morning. It was not part of the plan and the teacher and student could have just mistaken other students for Eric and Dylan.

8:36:45 - Eric purchases two propane tanks from Conoco gas station at 7450  W. Chatfield. The clerks initials were KLT. The recipt found in his home trash can is seen HERE. 

9:12:22 - Eric purchases one Blue Rhino propane tank from the Texaco. The store clerk describes him as quiet and polete. More information including the video and receipts can be seen HERE. 

11:14:55 - The CHS Janitor is seen on security footage entering the video room to swap recording tapes. The duffle bags are supposedly not visible in their final locations at this point. Recording is stopped at this point as the tapes are changed out. 

11:17:00 - The bombs that had been placed in the school were timed for 11:17am. They do not go off. Eric and Dylan are waiting outside in the parking lot. They are communicating using hand signals but when the bombs fail to detonate Eric likely approached Dylan to discuss the next step. 

11:19:00 - A 911 call comes in referencing the diversionary explosion on Wadsworth Road near Chatfield and Ken Caryl. 

11:20:00 - Another  911 call comes in referencing the diversionary explosion on Wadsworth Road near Chatfield and Ken Caryl. 

11:21:00 - Jefferson County Sheriff deputy Magor is dispatched southward, away from Columbine High School, to investigate the reports of the explosion off Wadsworth.

11:22:22 - The school janitor finishes swapping out the security tapes and the system begins recording again. The duffle bags are now visible in their locations.  

11:22:23 - Students in the cafeteria
