A South Boston man was charged with manslaughter today for allegedly throwing a glass that broke and sent shards of glass into a New York resident’s throat, killing him, inside a Lansdowne Street bar this weekend, Suffolk County District Attorney Daniel F. Conley said.

HECTOR GUARDIOLA (D.O.B. 5/8/85) was arraigned this morning in Roxbury District Court for the death of 23-year-old Michael Dimaria. Guardiola was additionally charged with two counts of assault and battery with a dangerous weapon for injuring two other people at the Lansdowne Pub near Fenway Park.

Assistant District Attorney Ian Polumbaum requested that Guardiola be held on $250,000 cash bail and noted that the defendant provided two different home addresses to authorities. District Court Judge David Weingarten set bail at $75,000 and ordered the defendant to surrender his passport to the court should he make bail.

Polumbaum told the court that, sometime after midnight Saturday morning, the defendant became engaged in a verbal confrontation with another patron “apparently over something trivial.” Polumbaum said no punches were thrown.

Dimaria was not the patron with whom Guardiola had argued.

After the two men separated, Polumbaum said, Guardiola “threw a heavy beer glass that hit something and shattered with sufficient force to hit three different people,” Polumbaum said.

Shards of glass struck a 22-year-old man in the head, causing what Polumbaum described as a “possible concussion” and required him to be treated with medical staples. A 23-year-old female was struck in the face, requiring stitches.

The glass that struck Dimaria in the neck “perforated his jugular vein and caused him to bleed to death,” Polumbaum said. Dimaria was rushed to Brigham and Women’s Hospital, where he was pronounced dead.

Polumbaum told the court that Guardiola was identified by multiple people as the person who threw the glass. In a post-Miranda statement to Boston Police detectives, Guardiola allegedly denied being involved in a confrontation.

Guardiola was represented for bail only by attorney Albert Hutton, Jr. He is expected to return to court on September 9.
