The story was first reported Monday, January 8 by ABC7 News.
The party took place at the home of Leanna Dawydiak and retired SFPD lawyer Reno Rapagnani, whose daughter Rose, 19, hosted the event. Members of the Baker's Dozen were in town as part of their winter tour.
Two uninvited guests made fun of the singers' coats and ties, and began taunting them with what one victim called homophobic names, and making threats, witnesses told ABC7 News, which reported the trouble started after the group sang "The Star Spangled Banner."
The television station reported that witnesses said that Richard Aicardi, 19, son of prominent pediatrician Eileen G. Aicardi, was the most aggressive, and allegedly called some friends to join him.
Aicardi said, "I'm 20 deep, my boys are coming," Reno Rapagnani told ABC7 investigative reporter Dan Noyes.
As the singers left the party to return to a home a block away where they were staying, two cars arrived and five to seven young men arrived and proceeded to harass, trip, and kick the students. They allegedly threw beer bottles, according to the Yale Daily News and the San Francisco Chronicle .

Aicardi's pique might have been spiked by school rivalry, as a Sacred Heart graduate, while Rose Rapagnani attended St. Ignatius, the Yale paper reported.
Baker's Dozen member Sharyar Aziz Jr. was thrown to the ground and kicked repeatedly. He was taken by paramedics to San Francisco General Hospital, and later had to undergo reconstructive surgery in New York for a broken jaw that is wired shut for eight weeks. ABC7 reported that he will have two titanium plates in his face.
He told the television station that Aicardi engaged in "juvenile taunting" and called a few members of the group "fag" or "homo."
