Halloween attraction "Field of Screams" was back open Saturday night with tighter security measures, 24 hours after a man died in a self-inflicted shooting while waiting to get into the park.

Police say a man and woman were arguing when he pulled out a gun and shot himself.

No one else was physically hurt, but the incident did leave many customers frightened.

The park says it has always banned weapons, but now it is taking extra steps to make sure people follow that rule. People who go Field of Screams now will be wanded by a metal detector, and security will check any bags.

One Ark City teen, who was in line when the gun went off, and her mom both say those security measures are exactly what they were hoping to see.

Aryonna White, 15, and her three friends were in line at Field of Screams Friday night when they heard a gunshot.

"It was really close," she said. "I can still remember the ring in my ear."

At first first, White thought it was part of the attraction.

"I thought it was just an act or something," she said.

Then, she said, a park employee told them someone had a gun.

"He said everyone get off the trailer and run towards the front, and I started panicking," White said. "That was the scariest. Everyone was just pushing each other to try to get to the exit and screaming," she said.

That's when White FaceTimed her mom, Brandy Long, who had driven the girls up from Ark City, and was waiting for the girls nearby.

"She's like 'Mom look,' and she holds her phone up, and there's cops everywhere and ambulances, and I was just, oh my God," Long said. "She said a gun had been fired and that people were running for their lives. I was so scared," she said.

Long says she rushed to the park to find her daughter.

"The girls were crying they were upset," Long said. "It's someone they'll live with for the rest of their lives, that they were so close to someone that shot themselves," she said.

The park says it's always had a no weapons policy, with clear signs.

Now it has added a metal detector checkpoint, where security can also check bags.

"We're really sad this happened and we don't anticipate anything happening again. We just want everybody to know we're doing everything we can so they're safe when they come out," said Jody Scott with Prairie Pine Festivals, which operates Field of Screams.

Both Long and White say all Halloween attractions should have tighter security.

"I just don't think a gun is a place to have in a maze for children and people go for family fun. I just don't," Long said.

They say what happened could have turned out much worse.

"We got lucky," White said.

"We were fortunate they all made it out of there and they're all okay," Long said.

The park says it has never had anything like this happen in its 13 years of being open. Scott says she's grateful for all the support the park has received from the community since the incident Friday.

Here's the full statement the park sent to Eyewitness News:

"Our intent is to open as usual tonight. We have had overwhelming support from the Maize and Wichita communities and from our Field of Screams family. We have been encouraged to go on with the production as scheduled.

The altercation and suicide was an isolated personal issue between two guests and was not connected with Prairie Pines, Field of Screams or any of our staff and performers. We are proud of the way everything was handled last night by all the staff and guests and we feel confident that we have a very safe event.

We have always had very high security at our Field of Screams event. Prairie Pines and Field of Screams is a place where parents feel comfortable dropping off their teenagers and parents bring their families for a fun night. We currently employ 6-10 police officers and security personnel during the event hours. We also currently have a policy of no weapons on the property during our event. With that being said, we will immediately begin using metal detectors and bag searches at our event. People are used to the types of searches at large concerts so we feel that our patrons will appreciate the added level of security. We want to assure everyone that Prairie Pines is a very safe venue.

Again, we want to commend all of the Maize and Wichita law enforcement as well as the patrons in attendance for handling everything so professionally and calmly. Additionally, we are very proud of the professionalism of our own staff. No one felt unsafe at any point in the evening.

Sincerely,

Kip and Jody Scott, Prairie Pines Festivals"
