Gannon and two other police officers were searching a home at 109 Blueberry Lane in Marstons Mills, a village in Barnstable, when the fatal shooting took place. They were seeking to arrest Latanowich for violating his probation for a case in 2010 when he pleaded guilty to drug and gun charges. He was taken into custody again within an hour of the shooting.
“Sean was a wonderful, wonderful young man,” said Yarmouth Police Chief Frank Frederickson. “We’re going to miss him terribly.”
Massachusetts Governor Charlie Baker also extended his condolences:
“I am heartbroken to learn of the passing of Officer Gannon and my thoughts and prayers are with his family, loved ones, and the Yarmouth Police Department after this tragic loss,” he said in a statement.
Latanowich is said to have an extended adult criminal history with 28 cases against him in Barnstable district court alone. This includes a four-year state prison term and more than 110 entries on his criminal history.
Charges include a 2016 arrest in which he allegedly strangled a pregnant woman and vandalized her vehicle.
Gannon was a well-known K9 officer who also volunteered in the Big Brother project. He had served for eight years, initially joining Stonehill College Police Department and serving as a summer officer in Nantucket before joining Yarmouth Police Department.
