Special prosecutor Hank Brennan admits evidence mistake in Karen Read's murder retrial as defense requests mistrial, with legal experts divided on whether the error was intentional

On Friday, the jury heard lengthy testimony from an accident reconstruction expert first hired by the federal government, who is now retained by the defense, about the damage to Read’s SUV. The expert will continue his testimony Monday morning. The trial resumes at 9 a.m. Monday, which marks the start of the 8th week of testimony.
