A federal judge in Cleveland who dismissed a juror in an opioid trial on Friday for misconduct has denied mistrial requests from the defendant pharmacies.

U.S. District Judge Dan Polster, who is overseeing a trial that began on Oct. 4, dismissed Juror No. 4 after she admitted doing her own internet research on a topic brought up in testimony last week. The juror had shared copies of her research with the rest of the jury, prompting the defendants to file motions for mistrial on Sunday.
