Boston police announced on Monday that a bouncer was arrested for the fatal stabbing of a young veteran of the Marine Corps outside the bar where the suspect worked on St. Patrick's Day weekend.

The 23-year-old was found seriously injured outside Sons of Boston on Union Street around 7 p.m. Saturday. The Boston General Hospital pronounced him dead.

According to his Marine Corps record, he gained the rank of sergeant during this period. 2019 saw him deployed with the 11th Marine Expeditionary Unit. He had previously served with the 1st Marine Division's 3rd Assault Amphibious Battalion at Camp Pendleton, California.

He was an adventurer, a brave soul, and his mom said he joined the Marine Corps to change the world. He was unafraid of danger or discomfort or hunger or fatigue, or all the things Marines and other Military branches must undergo. He was honorable. He just wanted to make a difference.

Martinez received a Marine Corps Good Conduct Medal, a National Defense Service Medal, a Global War on Terrorism Expeditionary Medal, a Global War on Terrorism Service Medal, and a Sea Service Deployment Ribbon.

Suffolk County District Attorney's Office investigators said Martinez was celebrating St. Patrick's Day in the city with friends. That included another Marine, according to Apolonia Martinez.

We need to pull together in love and support," Suffolk County District Attorney Kevin Hayden said.

The East Boston homicide unit reported that it had identified Alvaro Larrama, 38, as the suspect after conducting an investigation. Mr. Larrama turned himself in at District A15 of Boston Police.

Lorraa, who works as a bouncer at Sons of Boston, was arraigned in the Boston Municipal Court on Monday afternoon.

A prosecutor said at the hearing that investigators located surveillance videos from multiple cameras showing the stabbing and what happened after it, including when the suspect went back into Sons of Boston to wash his hands, get new clothes, and leave.

Larrama is currently being held without bail, and Judge Steven Key ordered him to report to court on April 28 for a probable cause hearing.

Union Street is lined with bars and restaurants like Union Oyster House, Bell in Hand Tavern, Sons of Boston, and Hennesey's Bar. Investigators were observed operating in the area near Paddy O's and the area was closed to traffic.

Stabbing shut down bars around the area for the night.
