The trial for the man accused of killing Yarmouth Police Sgt. Sean Gannon in 2018 is set to begin today.
Thomas Latanowich is charged with murder and seven other charges in connection to Gannon’s death.
Today is the first day of jury selection in Barnstable Superior Court.
Latanowich is accused of shooting and killing Gannon while police were serving a warrant at a Marstons Mills home.
He is also accused of shooting Gannon’s K-9 partner Nero, who survived.
Latanowich’s defense attorneys are expected to argue he was acting in self-defense.
