ST. JOHN, Ind. — A Northwest Indiana high school was put on lockdown Wednesday morning after a report that a student may have had a weapon.

No gun was found, according to an update from authorities. Police responded to Lake Central High School in St. John around 9:30 a.m. after a report of an active shooter. Around 11 a.m., school officials said no shots were fired and that everyone was safe.

It’s good news for Elizabeth Clarke, one of several parents sitting and waiting outside Lake Central High School as the investigation unfolded.

“I had to get to my kids and make sure they were OK,” she said. “I mean, I know that I can’t do anything from out here but I’ve been in communication with her and told her that I’m here. Whenever she’s out, I’m going to be right here.”

Lauren Knopf was another parent who communicated with their child by phone amid news of an active shooter. She recalled the message she received from her daughter just before 10 a.m.

“Mom, we’re in lockdown, we thought it was a drill, but they’re saying it’s not a drill. They’re saying there’s a shooter,” Knopf said.

Authorities responded to the scene after police said a student heard what he believed to be someone loading a gun in the bathroom. He then called the police.

“We were all going there thinking that people were getting shot and that wasn’t the case,” said St. John Police Chief Steve Flores. “Obviously, we still wanted to double-check to make sure we didn’t miss anything. That nothing was found. Or they ditched the gun somewhere. So obviously, we had to go through room by room.”

Two students are being questioned about the initial 911 call, the school said. No one is in custody and no charges have been filled. An investigation is ongoing.

Parents breathed a sigh of relief, thankful their worst nightmares didn’t become a reality.

“They’re my everything,” she said. “They’re my reason for being, and just to hold her and hug her and see her is going to be happiness for me.”
