Dylan Kleboldās Autopsy Report
FINAL ANATOMIC DIAGNOSES:
1. Through and through close contact large calibre gunshot wound involving the left side of the head (region of the left temple) associated with:

2. Aspiration blood lower airway and lungs
COMMENT: The autopsy findings in this case reveal that the cause of death is due to brain injuries secondary to a close contact, large calibre, through and through gunshot wound involving the left side of the head. This gunshot wound is consistent with self-infliction.
This autopsy is performed in the Jefferson County Coronerās Office in Golden, Colorado on 04/22/99 at 10:30 a.m. This autopsy is done at the request of Dr. Nancy Bodelson, the Coroner of Jefferson County. The identification was made by fingerprints. Concerning location, this body is identified as #11. Members of Jefferson County Sheriffās Department attended the autopsy. I am assisted in the autopsy by Mr. Rob Kulbacki.
History: This is the case of a 17-year-old, white male who is allegedly a victim of a self-inflicted gunshot wound to the head. The decedent was found dead in the library at Columbine High School, and the death occurred on 04/22/99. No other history is available at the time of autopsy.

I found this saved on my computer from around a year ago so I thought I would share it.Ā I also have no idea if this is the real report so please keep that in mind.
