Here at the Barnstable Superior Court Friday morning, a jury has found Thomas Latanowich, of Somerville guilty of second-degree murder in the shooting of Yarmouth Police Sgt. Sean Gannon in 2018.
Latanowich was found guilty on all seven charges against him, including aggravated assault with a dangerous weapon, assault and battery with a dangerous weapon, using a firearm in commission of a felony, possession of a firearm without an FID card, possession of ammunition without an FID card and mistreating a police dog.
The jury delivered it’s verdict after several days of deliberation including asking the judge a series of questions, saying they were at an impasse over one charge regarding the shooting of the police dog, but had a consensus on the others.
Gannon, 32, the department’s K-9 officer was shot and killed while he and other officers were serving an arrest warrant at a home in Marstons Mills on April 12, 2018. Gannon’s K-9 partner Nero was also shot, but survived. Latanowich was wanted for violating his probation and was hiding in the attic of the house when investigators say he shot Gannon and Nero.
Latanowich’s attorney argued during the trial that his client did not know Gannon was a police officer when he shot him, saying he feared it was someone else with whom he had a dispute.
