Judge Threatens Mistrial In Chauvin Case After Prosecutors Attempt To Present Last-Minute Evidence

Judge Peter Cahill threatened to call a mistrial in Minnesota’s case against former Minneapolis Police Officer Derek Chauvin Wednesday after prosecutors tried to introduce additional evidence last-minute.

State prosecutors called Dr. Martin Tobin to testify a second time in the trial as a rebuttal witness to Dr. David Fowler, a witness for the defense on Wednesday, according to the Star Tribune. During his testimony, Fowler had posited that carbon monoxide from a nearby police vehicle potentially played a role in the death of George Floyd.
