Superior Court Judge Sarah W. Ellis is presiding.
Seven jurors were chosen on Friday, and on Monday, several more were seated for a total of 15. Opening statements are set to follow later Monday, officials said.
Crosbie is accused of raping a woman while she slept in March 2024, when he was in Boston to participate in St. Patrick’s Day parade with fellow members of the Dublin Fire Brigade.
Crosbie was originally scheduled to leave the United States after the parade on March 19, officials have said. But after Crosbie spoke with police on March 15, he went to Logan International Airport for a 10:10 p.m. flight bound for Ireland, officials said.
He boarded an earlier flight at 7 p.m., but was pulled off the airplane by State Police and arrested, officials said.
Prosecutors allege that Crosbie raped a “female stranger” at the Omni Parker House hotel in downtown Boston on March 14, 2024.
The woman, 28, had gone to dinner with coworkers at The Black Rose, a pub near Faneuil Hall, and met a man, Liam O’Brien, along with his fellow Irish firefighters, according to prosecutors and court records.
The woman told police on March 15 that she agreed to return to O’Brien’s room, which he was sharing with Crosbie, at the Omni Parker House.
Video shows that around 11:30 p.m., the woman left a restaurant with O’Brien and returned to the room, prosecutors said.
The pair had a consensual encounter in the room, according to prosecutors. O’Brien then fell asleep on one of two beds in the hotel room, and the woman went to sleep on the other bed, prosecutors said.
Crosbie left the hotel at 11:55 p.m., according to hotel security video, and swiped his key card back into the room at 1:55 a.m., prosecutors said. At some point in the night, the woman woke up as Crosbie was allegedly raping her, according to a police report.
The woman “tried to push the male off” and she said “What are you doing? Stop!” the report said. Crosbie said “this guy is sleeping, I know you want this. He fell asleep,” the woman told police.
The woman left at 2:15 a.m., 20 minutes after Crosbie entered the room, prosecutors said. She messaged a friend to say she had been assaulted and went to a hospital, where she spoke with police.
At a hearing in August, prosecutors requested a DNA swab from Crosbie for “comparative testing” A genital swab from the woman revealed male DNA, prosecutors said in court documents.
“In this case, a known DNA sample from the defendant will produce evidence relevant to the question of his guilt,” Assistant District Attorney Erin Murphy, chief of the domestic violence and sexual assault unit, wrote in court papers.
Crosbie objected to providing a sample on grounds of unreasonable searches and seizures, court filings show.
“My client is not concerned about what the DNA is going to return or say,” Reilly said at the time. “He is adamant that he had no physical contact with her.”
The status of the DNA testing wasn’t immediately clear on Monday.
