This case is the kind of legal puzzle that makes you wonder just how much we really know about the human brain. A Texas jury just found 21-year-old Benjamin Elliott guilty of murder for stabbing his twin sister, Meghan, in the neck while she slept. The twist? Elliott claims he was sleepwalking at the time.
Let’s rewind to 2021. Elliott was just 17 when he plunged a survival knife into his sister’s neck in their family home in Katy, Texas. According to his version of events, he was deep in a dream, completely unaware of what he was doing—until he suddenly snapped awake and realized the horror in front of him.
In his initial statement to investigators, Elliott said: “I freaked out and, like, put the knife down and put a pillow on her to try and stop the bleeding. Then called, you know, 911 from my phone.”
But Meghan’s injuries were fatal. No amount of frantic backpedaling could undo what had just happened.
After five hours of deliberation, the jury delivered its verdict: guilty of murder. The judge then handed down a 15-year sentence—far less than the 99 years he could have faced. And why? Because the jury itself asked for leniency.
From the very beginning, Elliott’s lawyer, Wes Rucker, built the entire defense on one question: Why would a kid with no motive, no history of violence, and a deep love for his sister do something this horrific—unless he wasn’t truly awake?
Sleepwalking as a legal defense isn’t unheard of, but it’s rare. The idea is that someone in a sleepwalking state is essentially on autopilot, moving and acting without conscious control. It’s not a crime of passion, not a premeditated attack—it’s just the brain misfiring in the worst way possible.
And Elliott’s family backed up his claim. His older sister even testified that he had a history of bizarre, trance-like episodes. One time, she recalled, he stood in a doorway with his eyes barely open, unresponsive. When she touched his shoulder, he simply turned and went back to bed, completely unaware of what had happened.
Sounds convincing, right?
Not according to the prosecution.
Prosecutors didn’t buy the sleepwalking angle for a second. While they couldn’t present a clear motive, they did drop some evidence suggesting Elliott was definitely awake shortly before the stabbing.
For one, he was using his phone about 20 minutes before the attack. That’s a pretty big red flag. Unless he was sleep-texting—(which, to be fair, is a thing, but not exactly common)—it suggests he was fully conscious leading up to the crime.
Then there was the way he handled the aftermath. Prosecutors argued that after stabbing Meghan, Elliott had the presence of mind to call 911 and even use a pillow to muffle her screams. That doesn’t sound like someone in a mindless sleepwalking state—it sounds like someone trying to control the situation.
Assistant District Attorney Megan Long put it bluntly:
"While I didn’t give you motive, I did give you premeditation. It’s not a coincidence that the knife he got the night before is the same knife he used to kill his sister.”
This left the jury in a tough spot. They clearly weren’t convinced by the sleepwalking defense, but they also weren’t sold on the idea that Elliott was a cold-blooded killer. If they had believed this was a calculated murder, they could have recommended a much harsher sentence. Instead, they asked the judge for leniency—which is exactly what he gave.
Not everyone agrees with the jury’s verdict. Neurologist Dr. Jerald Simmons, who testified for the defense, flat-out said:
"I think the jury got it wrong. It’s totally possible [to kill while sleepwalking]. If it wasn’t possible, I wouldn’t have taken this position.”
He pointed out that, while rare, similar cases have happened before. For example, back in 2010, a North Carolina man was found not guilty after claiming he was sleepwalking when he smothered his 4-year-old son and attacked two other children. In that case, experts testified that extreme stress and sleep deprivation could trigger violent sleepwalking episodes.
But in Elliott’s case? The jury just wasn’t convinced enough to let him walk free.
So, was Benjamin Elliott a tragic victim of a sleep disorder? Or did the jury just spare a young man from spending his entire life in prison because they weren’t totally sure of his intentions?
