Judge Beverly Cannone is a breakout star of the Karen Read case. Judge Belvin Perry, who oversaw Casey Anthony's trial, knows that feeling.

Biomechanical engineer testifies injuries inconsistent with taillight impact in Karen Read murder case, after judge interrupts his birthday message.

DEDHAM, Mass. (WLNE) — Closing arguments are set to begin Friday after Karen Read’s defense team officially rested its case. The prosecution decided it would not call any rebuttal witnesses, thereby ending testimony. Today, Judge Beverly Cannone will meet with lawyers to go through the language of the jury instructions.

The finish line is in sight for Karen Read ’s retrial as ARCCA biomechanics expert Andrew Rentschler, the last defense witness, continues his testimony Wednesday.

Read did not testify in her own defense, and her team did not call the people she accuses of killing O'Keefe or the investigator she said tried to frame her for his death.

Judge Beverly Cannone also denied the defense team’s motion for a mistrial based on what Read’s lawyers called “intentional misconduct” from prosecutor Hank Brennan.

Judge Beverly Cannone is sticking to her ruling, limiting the testimony of the former chief medical examiner of Rhode Island.
