Prosecutors called more than 30 witnesses, including 11 women who said the three men had sexually abused them. The brothers, who have pleaded not guilty, face life in prison if convicted.
Tracy Tutor said Mr. Alexander, a former top real estate agent in New York, drugged and assaulted her in 2014. Mr. Alexander and his two brothers are on trial for sex trafficking.
The judge denied a request for a mistrial and jurors heard from a woman who accused one of the brothers of filming her when she was a minor. The sex-trafficking trial resumes on Monday.
Alon, Oren and Tal Alexander face federal sex trafficking charges.
