Slain Yarmouth Sgt. Sean Gannon Remembered One Year Later

YARMOUTH, MA — The community stopped to remember Yarmouth Police Sgt. Sean Gannon Friday, a year after he was shot and killed while serving a warrant. Yarmouth Town Administrator Daniel Knapik ordered all flags to half-staff from sunrise to sunset and no public events were planned.

The 32-year-old K-9 officer was fatally shot on April 12, 2018. His dog, Nero, was also shot but survived. Thomas Latanowich, a "career criminal" with over 120 criminal charges on his record, has been charged with Gannon's murder.

The Yarmouth Police Department on Friday shared a four-minute tribute to Gannon, simply titled "Hero."

Gannon's widow, Dara, wrote a letter to the Cape Cod Times last week urging people to remember her husband by "showing up for others."

"That note or text you’ve been meaning to write but keep putting off — send it. Take time to ask a friend or a colleague how he or she is doing, and really listen," she wrote. "Own up to a mistake and make it right. Pick up the extra shift for someone who needs the time off. Buy a coffee or pay the toll for a stranger behind you. No gesture is too small."

Gannon said she will remember her husband privately on Friday.
