But another similarity between the Jonesboro and Parkland shootings stands out to former federal agent David Chipman.In the Marjory Stoneman Douglas High School shooting, for instance, suspect Nikolas Cruz, 19, allegedly pulled the fire alarm at the school and then started firing his AR-15 style weapon at students in the hallway.A notably similar scene unfolded at Westside Middle School 19 years and 11 months earlier. Jonesboro shooters Andrew Golden, then-11, and Mitchell Johnson, then-13, pulled the fire alarm after lunch and stood outside the door where they knew students would be fleeing. Then they opened fire.“The way in which they did it — pulled the fire alarm and then lay in wait for kids to leave the school — it’s certainly a cautionary tale for people who are planning to improve school security today,” said Chipman, who now works as a senior policy adviser at gun violence prevention advocacy group Giffords.As for Wright, the slain Jonesboro school teacher’s husband, he said he has never watched any coverage of these school shootings. “I can’t,” he said. But that was before the Parkland shooting unfolded before his eyes on Feb. 14 when he found himself at an airport surrounded by televisions showing the breaking news.“I’m stuck watching this, so I’m seeing all this take place and I don’t really know what’s going on,” Wright said.Facing the anniversaryThe start to every year is difficult for Wright because March 24 looms.“When January comes around, it’s like ‘OK, here it comes,’” he said, adding, “March — you start feeling it.”“The shooting in Florida really opened the floodgates a whole lot quicker than they normally do. It’s been real tough this week,” Wright said.Wright is “hopeful” about the new wave of activism that the Parkland students are leading, he said, adding that he’s happy about the March for Our Lives events, especially the one set to take over Pennsylvania Avenue in Washington, D.C.“I would love to go to D.C. and see those kids march. It would be nice,” he said.A trip to the nation’s capital doesn’t seem like it will be in the cards for Wright, though. He said he typically spends the day with his and Shannon’s 22-year-old son, who was 2 at the time of the shooting, doing something such as playing golf “to try and escape everything.”As for the students in Jonesboro, who happen to be on spring break this week, there is a March for Our Lives event scheduled at Jonesboro High School on Saturday, and the community last week hosted its annual memorial motorcycle ride that raises funds to maintain the garden dedicated to the victims of the 1998 shooting.“It boils down to this: You just don’t want another family to go through this. It doesn’t matter what anniversary it is,” Wright said. “They’re still gone, and it still hurts.”Copyright © 2018, ABC Radio. All rights reserved.
