‘I killed a cop’: Man accused of killing Yarmouth police officer texted girlfriend after shooting

YARMOUTH, MASS. (WHDH) – The man suspected of murdering Yarmouth Police Sgt. Sean Gannon called and texted his girlfriend several times after the deadly encounter in Barnstable in April, according to a newly released police report.

Moments after Gannon was shot in the head while serving an arrest warrant at a home on Blueberry Lane, the report said 29-year-old Thomas Lantanowich sent a series of frantic text messages as he hid in the attic before being captured.

“I shot a cop and I killed a cop,” Latanowich told his girlfriend, according to a report released by the Massachusetts State Police.

Gannon was pulled from the home and rushed to Cape Cod Hospital, where he later died. Gannon’s K-9 partner, Nero, was also shot and wounded during the incident on April 12. Nero was treated and has since been released from the hospital.

Latanowich remained barricaded in the home, repeatedly calling his girlfriend. In a series of text messages, each about a minute apart, Latanowich said: “I’m taking as many as I can. I already shot him. I killed a cop. I shot a K-9,” according to the police report.

Police made contact with Latanowich’s girlfriend and asked her to come to the scene, according to the report. She agreed and Latanowich came out of the home about three hours after police arrived on scene.

Latanowich has since been ordered held without bail on a murder charge.
