A deadly lightning strike in Jackson Township, New Jersey, turned a Cub Scout outing into mass chaos Wednesday night, a witness said.

Eleven boys and two girls with Cub Scout Troop 204 were getting an archery lesson at the Black Knight Bow Benders club when witnesses say, out of nowhere, a tree was struck by lightning. According to witnesses, it was cloudy at the time, but it wasn't raining and there were no severe weather warnings.

Robert Montgomery, a 61-year-old instructor from Cinnaminson, was killed, and at least 14 others were injured and taken to local hospitals for treatment.

Ten-year-old Ryan Coopey was among those injured.

"I turn around and look, and there's bodies on the ground. Adults, kids, burns, just other parents and kids screaming," father Tom Coopey said.

Coopey said troop leaders began performing CPR immediately, saving lives.

The impact of the strike knocked Ryan out of his socks and sneakers, which ended up being shredded by the impact, Coopey said.

He says his son is now resting as he heals from second-degree burns on his foot.

"He's still in shock. Anxiety is still up," he said.

Despite this traumatic event, Coopey says Ryan still wants to work his way up to Eagle Scout.

According to Scouts of America, all but one of its members were released from the hospital Wednesday night.

"Our thoughts and wishes for good health and healing are with all of those involved," the organization said in a statement, in part.  

"I thought it was a bomb"

Mike Luster, an instructor and 25-year member of Black Knight Bow Benders, said he was closest to the lightning strike.  

"It was a flash. I thought it was a bomb. And that was it, I was on the ground," he said. "It knocked me to the ground, and I'm like, what happened? Am I dead?"

Luster is grateful to have only injured his knee, but his friend and fellow volunteer instructor was killed.

"I'm still shaken. I'm still very upset, crying. It should've been me. That was my position," Luster said.

"He was a great man, a good volunteer. Helped the kids," archery club life member Bob Helle said.

Club members who were instructing the children say the strike was so powerful, one person was shot into a tree and the club's treasurer was injured, as well.

"He just said he got singed, looks like he got a sun tan, you know. He sounded OK to me when I just talked to him," Helle said.

Witnesses say police and paramedics arrived within minutes.

The Cub Scout troop plans to hold a thank you benefit for the first responders who helped in the near future, Coopey said.

How to protect yourself from lightning strikes

Charlie Woodrum with the National Weather Service says there are usually 20 lightning strike fatalities in the United States each year. This is the 12th lightning fatality of 2025 and the second in New Jersey.

"Lightning tends to strike the tallest object. It doesn't always necessarily strike the tallest object," Woodrum said.

The NWS says given how common lightning strikes are, it would be considered ineffective to issue lightning alerts or warnings because it could potentially reduce the effectiveness of other warnings, such as tornado warnings, that save lives and protect property.

Woodrum has some advice for the best way to protect yourself if you're caught outdoors and hear thunder or see lightning.

"Get to a lower point, avoid higher areas – taller hills, trees. You want to avoid all of the tallest objects and make your way to a full enclosed structure," he said.
