BARNSTABLE (CBS) – The jury in the trial of Thomas Latanowich, the man accused of shooting and killing Yarmouth Police Sgt. Sean Gannon, is deadlocked on one of the seven charges.

There were anxious moments in the courtroom Thursday afternoon as the jury asked the judge about the charge of mistreatment of a police dog, saying they can’t come to verdict for lack of evidence.

By midafternoon they declared an impasse on that charge and when it seemed they were close to finishing their deliberations, they went home for another day, having informed the judge of their dilemma.

Judge Jeffrey Locke twice told jurors to resume their deliberations making it clear even if they’re deadlocked on this one charge, it would not impact their verdicts on other charges including first degree murder as long as those verdicts were unanimous.
