Timeline of Robyn Anderson on 4/20
There’s many gaps in time, I’m working with what’s in the 11k. I tried to make this as accurate as possible
7:30am - Robyn enters the Columbine parking lot and takes notice of E&D’s absence. She talks to Zach Heckler about this, then the both of them meet up with Nate Dykeman and all walk into school together
9:20-9:25am - Robyn walks to 3rd period with Zach Heckler
10:15-11:10am - Robyn attends her Independent Study German class to watch a video on Earth Day
11:10-11:15am - Robyn leaves class and pulls her car to the teacher parking lot to pick up her friends Tammy and Monica to get lunch at Dairy Queen
11:25am - Robyn, Tammy, and Monica all return to Columbine and notice kids running and police cars
11:25am-3:00pm - Robyn, Tammy, and Monica are told by police to stay in the car. Robyn starts crying and they notice a man in a white shirt shooting out of the library window
3:00-3:30pm - Robyn is interviewed by police about what happened (she had no clue who the shooters were at this point). Afterwards Monica’s mother drives the three girls back to their houses
3:30pm - Robyn hears the description of the shooters on the radio and says to Tammy that it sounds like E&D
In the evening of 4/20, it’s known that Robyn confesses her involvement in buying the guns to Zach Heckler and her friend Kelli over the phone
