Since the attacks on Dec. 3, 2022, Duke Energy said it has incorporated security improvements such as more monitoring and cyberprotections, and is cooperating with law enforcement in the investigation.
But in Moore County, there are still no new leads, and many in the community have been left wondering why.

It's an attack that shook the community. Cameron Blue from Pinehurst remembers it like it was yesterday.
"I can't believe that it's been three years since this happened," Blue said.
Gunfire damaged two different substations, knocking out power to most of the county, for some, as many as five days. An 87-year-old woman, Karin Zoanelli, died without the power to her oxygen tanks.
"The news started releasing that it was an intentional attack. And a lot of people, myself included, I mean, it was just really shocking to think like, something like this could happen in our town, you know, in such a small town," Blue said.
After the attacks, then-Gov. Roy Cooper said, "Violence and sabotage will not be tolerated. And Moore County Sheriff Ronnie Fields said, "The individual that did the damage knew exactly what they were doing."
At the time, state and local leaders called it targeted. Possible motives at the time included domestic extremism or anti LGBT activity, as a local drag show was set to take place the same day.
Before the attack, the FBI had warned about electric infrastructure being a target for extremist ideology.
Some of the only evidence left behind were dozens of shell casings from a high-powered rifle.
"If it was a professional group, a domestic terrorism group. Why wouldn't they clean those up? You know, so to me, I just my feeling is it's going to be a younger group of people, nonprofessional, because of that, because of the evidence they left. So the police are going to be looking to compare that evidence to maybe similar crimes," said retired FBI agent Frank Brostrom.
On Wednesday, Fields says he understands the frustration about the lack of answers, saying, "Working alongside our state and federal partners, our detectives have followed every viable lead, interviewed numerous individuals, and devoted significant time and resources to uncovering the facts."
And three years later, some are wondering if they'll ever get justice.
"Make peace with that how you can. But I think for a lot of people, it's just it just seems kind of unfair. It seems unjust. Like this was a huge tragedy for our community. It was a crisis," Blue said.
The sheriff said there is still an ongoing reward of $100,000 for any information leading to arrests in the case.
