Karen Read crash expert admits he sent notes to defense, broke sequestration order in first trial

A crash reconstructionist whose testimony is expected to be key to Karen Read's defense admitted on the stand Monday, without jurors present, that he sent notes to her team during the first trial and received information about prior testimony despite a sequestration order. 

Dr. Daniel Wolfe testified during the first trial that damage to Read's SUV – the alleged murder weapon – was inconsistent in regard to a collision with John O'Keefe, the Boston police officer found dead on a colleague's front lawn during a blizzard on Jan.
