Barnstable, MA – Yarmouth Police Officer Sean Gannon was fatally shot while serving a warrant on Thursday.
Police said that Officer Gannon and his K9 partner Nero were trying to serve a warrant at a home on Blueberry Lane in the Marstons Mills section of Barnstable at about 3:30 pm on April 12.
The suspect barricaded himself inside the residence immediately after he shot Officer Gannon, and then a gunfight ensued with police, Time reported. A black, armored tactical vehicle was used to gain entry to the home, and take the suspect into custody.
Officer Gannon was transported by ambulance to Cape Cod Hospital in Hyannis where he died.
K9 Nero was taken for emergency veterinary care. His condition was unknown, Time reported.
The Cape and Islands District Attorney’s office identified the shooter as 29-year-old Thomas Latanowich of Somerville, a career criminal with at least 111 charges already on his record, the Somerville Patch reported.
Yarmouth Police Lieutenant Steven Xiarhos called him a "notorious and violent criminal" when he was arrested for stabbing a man who had just gotten out of prison in December of 2017.
Assistant District Attorney Tara L. Miltmore said in a statement that Latanowich will be charged with murder when he is arraigned Friday at First District Court in Barnstable.
Massachusetts Governor Charlie Baker extended his condolences on Thursday night.
“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,” Baker said in a statement, according to the Boston Globe.
“The Commonwealth is blessed to have courageous men and women who put their lives on the line to protect our communities every day," the governor wrote.
