A gunman may have shot three men dead over firewood near a West Virginia state park Monday evening, officials said.

Cops from the Washington County Sheriff's Office said a man who fled in a white pickup truck after gunning down three men at around 6 p.m. in rural Morgan County.

"It was a property dispute over some firewood or something of that nature," Morgan County Sheriff Vincent Shambaugh told the Journal News.

The gunman may be carrying an assault rifle, according to early reports. Police said the gunman opened fire, killing three people outside Cacapon State Park. Washington County Sheriff Douglas Mullendore confirmed the shooting — and said that the gunman remained on the loose.

"And there's a possibility he might be coming more toward the Washington County area," Mullendore told Herald-Mail Media. "That's why our deputies were dispatched." Mullendore told the Daily News that he was not allowed to give out any more information.

The gunman's direction of travel was not immediately known.

If confirmed, this is the second active shooter incident in the country in two days. Early Sunday, Omar Mateen, 29, shot and killed 49 people at the Pulse gay club in Orlando, Fla, officials said. The ISIS-inspired security guard then died in a standoff with police. The Pulse shooting is being considered the worst terror attack in the nation since the 2001 attack on the World Trade Center.
