A sea of blue today in Cape Cod honoring the life of Sgt. Sean Gannon.
The 32-year-old officer was shot and killed last week while serving a warrant in Barnstable.
Among the officers paying their respects was a Springfield Police Captain.
Capt. Brian Keenan said it was an emotional one for everyone there but it was comforting to see officers from all around the country; some as far away as California.
From California to Texas, to officers from across Massachusetts, Capt. Keenan was one of many officers from western Massachusetts that took the trip to Yarmouth.
Keenan said it's their duty to comfort a department and community in mourning.
"The Springfield Police Department makes an effort to send as many officers as we can to these funerals," Capt. Keenan noted.
He said after the loss of Springfield Police Officer Kevin Ambrose in 2012, the rest of the country paid their respects to the city.
Keenan added that now is the time to show the Yarmouth Police Department the same respect.
"The outpouring of support we received from the law enforcement community was overwhelming and we try to favor when we can. We just try to come home safe to our families every night and keep the public safe too," Keenan continued.
Sgt. Gannon leaves behind his wife. He was married for eight years.
His police dog, K9 Nero was also shot during the incident and was released from the animal hospital the same day Sgt. Gannon was laid to rest.
