Final Defense Witness Just Dropped a Bombshell in the Karen Read Trial—And It Changes Everything

Okay, let’s talk about the Karen Read case—because this thing just took a wild turn. You know, the one where they say she hit that Boston cop with her Lexus? Well, the defense called their last witness, some biomechanics guy named Dr. Andrew Rentschler, and buddy… he basically said the prosecution’s whole story might be garbage. No joke. According to him, there’s zero biomechanical proof that the Lexus even touched the guy. So… now what?

Here’s What the Prosecution’s Been Saying

Right, so the DA’s office claims Karen got mad, threw her Lexus in reverse, and plowed into Officer O’Keefe on purpose. They’ve got some dents on the car, a couple witnesses who maybe saw something, and forensic stuff that supposedly lines up. Classic “she did it” narrative. But here’s the thing—when you actually look at the details? It’s shaky. Like, really shaky.

Enter Dr. Rentschler—The Guy Who Might’ve Just Saved Karen’s Butt

So this biomechanics expert walks in, drops the mic, and says O’Keefe’s injuries don’t match what’d happen if a car hit him at 24 mph in reverse. At all. And let’s be real—have you ever tried speeding backward in an SUV? Those things aren’t exactly built for reverse drag racing. Rentschler’s point? The math ain’t mathing.

“Look,” he said in court, “if a 24 mph car hit him, we’d see way different damage. This? This looks like something else entirely.” Mic drop.

Why This Changes Everything

Let me break it down:

• The injuries don’t add up: No major blunt force trauma where there should be. That’s like saying you got a black eye from a pillow fight.
• 24 mph in reverse? Seriously? I drove a Lexus once. You’re lucky if it hits 10 mph backing up.
• Biggest twist: Rentschler thinks O’Keefe might’ve just… fallen. Or gotten into a fight. But a car? Nah.

Questions the Jury’s Gotta Be Asking Now

You can bet the defense is hammering these points:

• Can a Lexus even DO 24 in reverse? (Spoiler: Nope. Not unless it’s been modded by Fast & Furious crew.)
• If the science says no car impact, what’s left of the case? Not much, honestly.
• And if it wasn’t the Lexus… what actually happened that night? That’s the million-dollar question.

People Are Losing Their Minds Over This

Twitter’s on fire. Reddit threads are longer than the Bible. Legal folks are split—some say Rentschler just handed the defense a golden ticket, while prosecutors are calling it “science fiction.” But here’s what matters: what the jury thinks. And right now? Nobody knows.

What Happens Next?

We’re heading into closing arguments, and suddenly the whole case feels like a house of cards. If the jury buys Rentschler’s take? Karen could walk. If not? Well… let’s just say Massachusetts prisons aren’t exactly five-star resorts. It all comes down to one thing: did that Lexus actually hit O’Keefe, or is this whole case built on bad science?

Final Thoughts

Look, trials are messy. But when a scientist gets up there and says “the physics don’t work,” you’ve gotta listen. Maybe Karen’s guilty. Maybe she’s not. But if I were on that jury? I’d need way better evidence than what they’ve shown so far. What about you—think the biomechanics defense holds up, or is it just smoke and mirrors?
