Warrant service, deadly shooting of Sgt. Gannon outlined in new report from DA

YARMOUTH, Mass. – Investigators on Cape Cod have released new details about the death of Yarmouth Police Sgt. Sean Gannon who was shot and killed while serving a warrant last month.

Sgt. Gannon and his K-9 partner Nero were part of a team attempting to serve an arrest warrant on 29-year-old Thomas Latanowich at a home on Blueberry Lane in Marstons Mills.

The new report from Cape and Islands District Attorney Michael O’Keefe outlines exactly what happened that day in detail.

According to the report, Gannon, Nero and another officer entered an unfinished attic through a bedroom closet after clearing the rest of the home.

The officers found two backpacks in the attic, one containing a large amount of drugs and the other containing clothing according to the DA’s report.

Without finding anything else, the officers left the attic, but a short time later returned after finding signs there might be a person up there.

On the second look, the team of officers discovered a piece of insulation that was covering an opening into another portion of the attic.

The DA says Gannon was shot in the head immediately after moving that piece of insulation. Nero was also shot.

The officers he was with pulled him out of the attic and he was eventually taken to Cape Cod Hospital where he was pronounced dead.

After an extended standoff, Latanowich surrendered and was taken into custody. After that officers returned to the attic to recover the injured K-9.

Latanowich has been charged with Murder in the first degree and one count of Mistreating a Police Dog.
