“The part-time police officer on a call with Cold Spring officer Thomas Decker when he was killed may have ‘froze’ instead of going after the killer and hasn’t been able to recount important details of the shooting, according to a source with direct knowledge of the case.

“The source said Thursday that the team of investigators trying to find the killer is ‘completely befuddled’ over the second officer’s apparent inability to give a detailed description of Decker’s killer or events surrounding the crime.

“‘They are looking at the other cop’s actions and whether there was a failure to act,’ the source said, via Star Tribune.
