A retired police chief on how officers handled the scene in Canton

Karen Read's heated voicemails for John O'Keefe were played in court Tuesday, while the defense pressed police about their search of the property and evidence they found. Tonight on "Canton Confidential," we take a look at the investigation through the eyes of a retired area police chief, and ask an NBC News legal analyst who's been following the case what's attracted his attention — he tells us what's so unique about it.    You can watch the TV version of this episode — and all the others, as well as video from court as it happens — on our YouTube page.
