HINGHAM – After barricading himself in his home, a Hingham man was found dead from a gunshot wound following a 10-hour standoff with police.

State Police detectives assigned to the Plymouth County District Attorney’s Office are investigating the suicide of a man who barricaded himself in a Hingham home overnight Saturday.

Police surrounded the home at 4 Edgar Walker Court in the Conservatory Park neighborhood around 9 p.m. Saturday night after receiving a report that a distraught man was barricaded inside.

An acquaintance of the man initially called Weymouth Police to report that he was making suicidal threats over the phone, and Hingham Police were notified, according to emergency radio transmissions.

Hingham Police secured the perimeter of the home and contacted Metropolitan Law Enforcement Council, who responded with a regional SWAT team. Several police dogs were also called in.

As the sun rose on Sunday morning, Hingham Police activated an automated call to Hingham residents in the area notifying them of the situation and to stay in their homes.

Hingham Police found the man dead from a gunshot wound inside the home at 7:15 a.m. Sunday morning, according to Beth Stone, a spokesperson for the Plymouth County District Attorney’s Office.

Stone did not release the name of the man, who was 26 years old, according to emergency radio transmission during the incident.

Hingham Police contacted State Police Detectives assigned to the Plymouth County District Attorney’s Office to investigate the suicide. The state Office of Chief Medical Examiner also responded to the scene.

Sgt. Steven Dearth said the danger was confined to the house, but referred all further questions to the Plymouth District Attorney’s Office.

Edgar Walker Court is quiet cul-de-sac with large colonial-style homes near South Shore Country Club.
