Accused cop killer indicted on 9 charges


BARNSTABLE, Mass. (WPRI) — A Barnstable County grand jury handed up an indictment Wednesday charging a man with the murder of Yarmouth Police Sgt. Sean Gannon.

Gannon and his K-9, Nero, were shot on April 12 as they and other officers attempted to serve a warrant to Thomas Latanowich at a home in Barnstable. 

Gannon, 32, was rushed to Cape Cod Hospital, where he later died. A native of New Bedford, Gannon was remembered fondly by his colleagues in law enforcement, who have since held a charity 5K race and stuffed animal drive in his honor.

Nero was taken to a veterinary hospital with serious injuries but ultimately survived the shooting, and has since been in recovery.

The grand jury has been hearing evidence in the case since April 26, according to Cape & Islands District Attorney Michael O’Keefe. They indicted Latanowich on charges of murder, aggravated assault and battery with a dangerous weapon, assault and battery with a dangerous weapon, use of a firearm in the commission of a felony, possession of a firearm without a license (subsequent offense), carrying a loaded firearm without a license, possession of ammunition without an FID card, mistreating a police dog, and armed career criminal.

Latanowich, 30, will be arraigned in Barnstable Superior Court and remains held without bail.
