Thomas Latanowich, Accused of Killing Yarmouth Officer Sean Gannon, Held Without Bail

April 13, 2018 GMT

BARNSTABLE -- Thomas Latanowich, 29, pleaded not guilty to murder this morning in the shooting death of Yarmouth Police K-9 officer Sean Gannon.

Latanowich was held without bail, at Barnstable District Court. His next hearing will be June 26.

The court room was filled during the arraignment with police officers from Yarmouth and Barnstable Police Departments during the arraignment.

Latanowich entered the court with his head down. He made no eye contact with anyone in the court.

Yarmouth Police Chief Frank Frederickson called Gannon a “remarkable young man.”

“We refer to him as the Tom Brady of the Yarmouth Police Department and he’s gone. He died doing what he loved.”

“And we have a devastated community, family and police department,” Frederickson said.

Cape and Islands District Attorney Michael O’Keefe said Gannon, 32, was shot attempting to deliver a warrant for a probation violation.

“His last sentence from us was a 4 to 5 state prison for a variety of gun charges, O’Keefe said. “He had a probationary sentence after that. The reason that there was an outstanding warrant for him was that he violated his probation, which was transferred from the Barnstable Superior Court up to Middlesex County and the Middlesex Superior Court issued the warrant that was the subject of yesterday’s apprehension.”

Peter Shaughnessy, principal of Bishop Stang High School in Dartmouth, said Gannon graduated from the school in 2003.

“The Gannons are wonderful, wonderful people, of faith and service, devoted to making our community here at Stang and on the South Coast,” Shaughnessy said. “We’ll definitely be always remembering his sacrifice and his service here.”

Shaughnessy said the school will create a memorial for Gannon on school grounds.

Gannon’s dog, Nero, was also shot. Dennis Veterinary Hospital posted on Facebook that Nero was shot in the face and neck but has been stabilized and faces surgery Friday.

“Sean was a talented and dedicated police officer who excelled during his three years at the College,” said Stonehill spokesperson Martin McGovern. “His colleagues and friends in the Stonehill College Police Department are heartbroken by his death as is everyone in the Stonehill community who knew him. He has many friends on campus and their hearts go out to his family and his colleagues in the Yarmouth Police Department.”

“Around 3:30, a local police officer (was) shot during a warrant service at 109 Blueberry Lane, Barnstable,” state police spokesman David Procopio told the Herald in an email last night.

Police, including the K-9 team, had gone to the house to arrest Latanowich, who was wanted on a prior charge and was considered dangerous.

Latanowich -- whose last known address was in Somerville -- was apparently hiding in the attic and shot Gannon and his dog as the K-9 team started to enter the attic, a law enforcement official confirmed.
