What Columbine book am I thinking of?

I remember reading a very interesting passage in a book about Columbine in which the author describes the process by which the police determined that Eric Harris and Dylan Klebold were the perpetrators of the Columbine Massacre. This process by which the police determined that Eric Harris and Dylan Klebold were the perpetrators of the massacre occurring before Eric and Dylan committed suicide. I have been trying to find this book for several days. Before today, I thought the book I am thinking of is Ralph Larkin's Comprehending Columbine. However, I believe I read the entire e-book of Comprehending Columbine today, and I never saw the passage about the process by which the police determined Eric and Dylan were the perpetrators. I don't definitely know, but I don't think that the passage I am thinking of is from Cullen's book Columbine or Brooks Brown's book No Easy Answers. Perhaps the passage I am thinking about was in some source other than a book.

What Columbine book am I thinking of?

HMM. Maybe Jeff Kass's book, Columbine: A True Crime Story?

I don't know which book it is, but commenting here so I can see the answer when someone does figure it out!

I also thought that Jeff Kass' book Columbine: A True Crime Story is probably the book that I was thinking of. However, I read the book in the last few days. Columbine: A True Crime Story is not the book I was thinking of.

The books I have read on Columbine is as follows(and in no particular order).

Jeff Kass- Columbine: A true Crime Story
Brooks Brown- No Easy Answers
Sue Klebold- A Mother's Reckoning
Dave Cullen- Columbine
Ralph W. Larkin- Comprehending Columbine

I am waiting for the day I can add Randy Brown's book to my list!  

But if what you are talking about isn't in these, then maybe it was indeed in a news article/report or some other book that I haven't read.    Hope you find it!
