NC, Southport, reports of a mass shooting at Southport Yacht Basin, September 27th 2025.

Did all his strange paranoid behaviors begin only after that brain injury or is there evidence of him being "different" before that also?

I assume he would've had to demonstrate a certain level of psychological health in order to join the military, but who knows what might have happened since then

Seems he joined the military after 9/11, so that tells me he was someone with fixed determination, which is admirable but perhaps also allows beliefs to get "stuck" to the point of becoming paranoid and obsessive.

I am in no way qualified to know, but am wondering.

I do think his serious head injury, plus what seems like very traumatic emotional experience while in combat, had severe effects on him. When we send young people off to war, we have to accept them back again, and it seems some are left floundering. imo

Book overview​

Sean DeBevoise learned early on growing up in New York State that he was bound to be a man of honor. Hunting in the Catskill Mountains with his father, Sean learned about nature, focus, and ultimately, survival. During high school, he was a wrestler, and that's when he met Rachel, the woman who would ultimately become his wife and be the centerpiece for an unconventional tale. After the attacks of 9/11, Sean knew that his only course of action was to serve his country. Joining the Marines, he found a mental and physical challenge that he planned to excel at. Although he sensed the behavior and many things said by fellow Marines to be disturbing, he willingly deployed to Iraq where he encountered a war-zone that would rip his body to shreds. Taking four bullets including one to the head, Sean's life would never be the same, but it was the fact that all of this was at the hand of friendly fire that would provide the most crippling mental damage. Sean DeBevoise was nearly killed by his own Marines, and for reasons that are boggling to the outside mind. Putting the pieces together still today, Sean has come to realize that a dangerous web was woven between the US Marines, a hunger for honor, and jealously that traced all the way back to his family at home. Sean killed insurgents on that fateful day when he was locked in a warehouse and left to die by his own men. Returning home, the nightmare seemed to become even more horrifying. Although he has worked tirelessly to recover the use of his body and to reclaim his life from those who did everything in their power to take it from him, he still grapples with a mysterious story that the US military doesn't want you to know. This is Sean's story, and it's being told for the first time with unflinching honesty.

No doubt he was a hero, but when reading through the reviews, especially that of his relative, it becomes obvious that the story is told by the man who has sustained a major brain/body trauma and is suffering from the devastating consequences ot it. We don't know what happened in Iraq. I suspect that the injury has changed his reconstruction of the past as well. His story is horrifying and saddening, but the world he portrays is viewed through the lens of distorted thinking and altered perception caused by the trauma. It is the situation when you feel incredible compassion because the man's decision was prompted by the wish to protect his country after 9/11. Yet you understand that now it is impossible to reason with him at all.

It is in the hands of the court, but...he is not at fault that the bullet has damaged his brain.
Good luck to the judge on the case. The society has to be protected from Nigel Edge, no doubt, and yet he once volunteered to defend his country, served bravely, and got a wound in the head that made him what he is.

That says it all.

When we send young people off to war, we have to accept them back again....and put them back together again if they need it. This vet was broken and, it seems, left to flounder. I'm not sure what would've helped him as that's beyond my knowledge, but it is sad he literally put his life on the line in our military and it ended up not only ruining him, but the lives of innocent civilians in North Carolina.

He is certainly not the only vet to come home wounded physcially and psychologically - the conditions are as old as war itself.

I am NOT excusing him, but acknowledging it's a complicated situation and it's humanly possible to feel compassion, disappointment, grief, fear, and anger all at the same time.

So have there been literally NO reports of him being mentally unstable at all before he was shot in the head in the warzone? Has no one who knew him from before he enlisted come forward with stories of him being delusional or anything like that in his earlier days?

This article is from 2017 and it sure sounds like he was living life to the fullest, making the best out of what he was dealt and staying plugged in to the community with a girlfriend and friends who seemed to think highly of him. So I'd say some time after 2017 and 2020 is where something really shifted.

Finding purpose

While serving as a sniper in Iraq, Sean DeBevoise was shot four times during a firefight; 11 years later he's chasing a dream to make a living out on the ocean.

The delayed onset of psychosis isn’t uncommon after a severe TBI. This may be due to brain atrophy.

https://psychiatryonline.org/doi/full/10.1176/jnp.13.1.61

The onset of psychosis after TBI is highly variable but is generally delayed. In their study of World War II veterans, Achte et al. reported that the occurrence of psychotic symptoms ranged from 2 days to 48 years after injury, with 42% experiencing their first psychotic episode 10 or more years after sustaining a missile wound to the head. Fujii and Ahmed reported a range from 3 months to 19 years with a mean onset of 5.9 years after closed head trauma. And Feinstein and Ron reported a mean latency of 11.7 years with a range of 0 to 52 years.

Consistent with our hypotheses, the current findings suggest that hippocampal degeneration in the chronic stages of moderate-to-severe traumatic brain injury may play a role in the delayed onset of psychotic symptoms after traumatic brain injury. These findings localized to the right hippocampal head are supportive of a proposed aetiological mechanism whereby atrophy of the hippocampal head may lead to the dysregulation of dopaminergic networks following traumatic brain injury; possibly accounting for observed clinical features of psychotic disorder after traumatic brain injury (including prolonged latency period to symptom onset and predominance of positive symptoms).

Very good find, @cujenn81! This sounds like what he has gone through given what we know of his timeline and the little we know of his life history so far. I'm sure stuff like this will figure in to his court proceedings. Wonder how this will affect everything for him.
