Fingerprint testing performed on the can opener proved negative - Kaeseman's fingerprint were not found on the can opener.

The officers said they "feared for their lives" because the "suspect" had the alleged "shiney object" in his right hand. Unknown to the officers when they got "their story straight" Kaeseman was left-handed.
Alleged "shiney object"

The alleged "shiney object", sealed in an evidence envelope has the initials "JCR" (in black magic marker shown above) which happen to be the same initials of the officer whose name appears on the evidence envelope below -- J. C. Rowe.

Officer Rowe, are you missing a can opener ?
