ABC News’ Olivia Rubin and civil trial attorney Tre Lovell discuss testimony from Daniel Wolfe, the director of an accident reconstruction company.

DEDHAM, Mass. — Lawyers in the murder trial of Karen Read began giving their closing arguments Friday after weeks of testimony in a highly divisive case in which the prosecution’s theory of jaded love turned deadly is countered by a defense claim that a cast of tight-knit Boston area law enforcement killed a fellow police officer.

For the second time in less than a week, Karen Read's defense team called for a mistrial in her retrial. Here's what else happened on day 29.

A key Karen Read defense crash reconstruction expert testified that damage to her SUV — the alleged murder weapon — and wounds to boyfriend John O’Keefe’s arm are “inconsistent” with a vehicle

Crash reconstruction expert Dr. Daniel Wolfe testifies that damage to Karen Read's 2021 Lexus SUV taillight is inconsistent with hitting John O'Keefe.

For weeks, all appearances were that prosecutors would call witnesses as part of a brief rebuttal case in the Karen Read retrial, giving them the opportunity to get the last word after damaging testimony from expert witnesses for the defense.

A jury will soon deliberate on Read's fate. She is accused of killing her Boston cop boyfriend in a fit of drunken jealousy in 2022.

Karen Read has said her team will likely call its final witness on Tuesday, so there are not many more witnesses to be called by the defense.
