The parents of a Boston University freshman who died after becoming intoxicated at a 2013 pledge party are suing the fraternity and three members of the organization in federal court for wrongful death.
An autopsy of Anthony Barksdale II found that his blood alcohol level at the time of his death was .33 percent.
The family is suing the national Sigma Alpha Mu fraternity, the BU chapter's then-president, vice president and another brother.
The lawsuit alleges fraternity members handed Barksdale a bottle of vodka and forced him to drink its entire contents.
Barksdale collapsed at the party and was later pronounced dead.
The national fraternity office didn't immediately return requests for comment.
