Police named 40-year-old Nigel Max Edge as the suspect in a Saturday mass shooting in North Carolina that killed three people and injured five, who are still receiving care.

Edge was arrested on Sunday and is charged with three counts of first-degree murder, five counts of attempted first-degree murder, and five counts of assault with a deadly weapon with intent to kill. He is currently held without bond.

Newsweek has reached out to the Southport police office for comment via email on Sunday.

So far this year, the nonprofit organization Gun Violence Archive (GVA), has tracked 321 mass shootings in the United States. Mass shootings are most often defined as an incident where at least four people are shot.

North Carolina has the death penalty, and District Attorney John David said Sunday that “my office does seek it in appropriate cases.”

On Saturday evening at approximately 9:30 p.m., the Southport Police Department responded to reports of gunfire and multiple injuries at the American Fish Company in Southport, North Carolina.

A single-occupant boat traveling on the Cape Fear River briefly stopped near the restaurant and opened fire, authorities said. The boat then left the area, heading toward the Intracoastal Waterway in the direction of Oak Island.

Southport police chief Todd Coring said during a Sunday press conference that authorities believe it was a “targeted location,” and the actwas “highly premeditated.” He added that the suspect acted as a “lone wolf,” and used an assault rifle.

Shortly after 10 p.m., the U.S. Coast Guard reported locating an individual matching the suspect’s description at the public boat ramp on NE 55th Street in Oak Island, around 20 miles from the border with South Carolina.

During the Sunday press conference, Coring said the suspect in custody “identifies as a combat veteran, he self-identified as injured in the line of duty,” adding that he says he “suffers from PTSD [post-traumatic stress disorder].”

Charlie Boris, of the Oak Island Police Department, confirmed on Sunday that Edge is a resident of Oak Island, noting that “we are familiar with him at the police department.” David noted that “there were some minor contacts over the years, but nothing significant in the past which would give us any indication that he was capable of such horror.”

Authorities emphasized that the investigation is in its early stages and that they will cross-reference findings with criminal records from other states.

They also confirmed on Sunday that “Mr. Nigel Edge actually changed his name some years ago,” adding that they are working to identify “all of his past.”

One authority referred to him as “Sean,” and according to public records that Newsweek obtained, he previously identified as Sean DeBevoise. Records show that DeBevoise had several hunting and fishing licenses across states, including North Dakota, Georgia, Florida, Virginia, and North Carolina.

Public records also show that DeBevoise also had several run ins with the law, though none of the six offenses were specified, they took place in North Carolina in 2006, 2008, and 2015.   

The Wilmington Star-News wrote a story about DeBevoise in 2017, identifying him as a former Marine sniper who was shot while serving in Iraq in 2006.

According to a 2020 self-published book on Amazon, Headshot: Betrayal of a Nation (Truth Hurts), DeBevoise wrote that on tour, he took “four bullets including one to the head.” He said from that moment onhis “life would never be the same,” adding that “all of this was at the hand of friendly fire that would provide the most crippling mental damage.”

The book’s description also reads, “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.”

DeBevoise grew up hunting with his father in New York and learned about “nature, focus, and ultimately, survival,” he said in the description. He was a high school wrestler, according to the book, and enlisted in the Marines following the September 11, 2001, terrorist attacks.

Authorities emphasized that this is an ongoing investigation and anyone with any information regarding the suspect of the incident should report it to law enforcement.

David said on Sunday that “I anticipate additional charges could be forthcoming.”
