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 on Blueberry Lane in the village of Martsons Mills.

Gannon's police dog, Nero, was also shot. The dog was listed in stable condition Friday morning.

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.

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."
