Cape Cod Police Officer Gunned Down

BARNSTABLE, MA — A Cape Cod K-9 officer was shot and killed Thursday in Barnstable while serving a warrant to a career criminal with more than 100 priors. State Police said Yarmouth officer Sean Gannon, 32, was pronounced dead at Cape Cod Hospital. The shooting happened in on Blueberry Lane in the village of Martsons Mills.

Gannon’s police dog was injured. Its condition is unknown.

The suspect, 29-year-old Thomas Latanowich, of Somerville, was taken into custody after a standoff. Police said he will be charged with murder. Latanowich was the subject of the warrant being served.

Yarmouth and Barnstable police frequently team up while serving warrants.

Latanowich has more than 111 charges on his record. He was arrested in December after allegedly stabbing a man who had just been released from prison. At the time, Yarmouth Lt. Steven Xiarhos called him a “notorious and violent criminal.”


Law enforcement agencies from Massachusetts and beyond expressed their condolences over social media.

“Rest easy brother, we have the watch from here,” the Wareham Department of Natural Resources wrote over Facebook.

“Our hearts are heavy as our thoughts turn to our brothers and sisters of the Yarmouth Police Department during this most difficult time,” Seekonk Police tweeted.

Falmouth police tweeted, “Our thoughts and prayers are with the fallen Yarmouth Police Officer’s family and friends, as well as the members of the Yarmouth Police Dept. and Cape Cod Regional Law Enforcement Council SWAT Team. We ask that you also keep them in your prayers.”
