Latanowich Convicted of Killing Yarmouth Police Officer
BARNSTABLE — A man described by prosecutors as a career criminal has been convicted of killing a Cape Cod police officer who was helping serve an arrest warrant at a home in 2018.
After nearly three full days of deliberations, a jury on Friday found Thomas Latanowich, of Somerville, guilty of second-degree murder in the fatal shooting of Yarmouth police Sgt. Sean Gannon.
Gannon was the department's K-9 officer.
He was killed in April 2018 while he and other officers were serving an arrest warrant at a Barnstable home for a possible probation violation.
Gannon’s dog, Nero, also was shot but survived.
