The Maryland teenager who terrorized his high school used his father's handgun to shoot a girl he'd just broken up with and another classmate, investigators said Wednesday.
Austin Wyatt Rollins, 17, was later killed when he traded shots with the school resource officer at Great Mills High School, they said.
"Rollins and the female victim had a prior relationship that recently ended," the St. Mary's County Sheriff's Office said in a statement. "The handgun utilized by Rollins in the shooting was legally owned by Rollins' father."
Rollins' alleged target, 16-year-old Jaelynn Willey, remains in critical condition at a local hospital. But a 14-year-old boy who happened to be in a hallway when Rollins opened fire was released after being treated for a gunshot wound to the leg.
It was not clear how the teenager, who lived in Lexington Park, Maryland, got hold of his father's weapon or what make or caliber it is.
The National Rifle Association has been quick to point to Gaskill as proof that armed guards and teachers are a better deterrent than gun control. But Gaskill faced a teenager armed with a handgun, not a rifle like the Parkland shooter.
Nevetheless, what Gaskill is reported to have done is extremely rare.
The Washington Post, which has done an analysis of dozens of school shootings, reported Wednesday that Gaskill would only be the second school resource officer to kill an active shooter since the 1999 Columbine High School massacre.
In the aftermath of the Parkland mass killing, President Donald Trump has called for arming teachers — an idea praised by the NRA and dismissed as a “colossally stupid idea” by many educators and school safety advocates.
Still, Florida Gov. Rick Scott last month inked a new law that defied the NRA by raising the age to buy all firearms to 21 and imposed other gun-buying restrictions — but also allowed trained school workers and teachers to arm themselves.
Meanwhile, Gaskill got a shout out Wednesday from Stephen Willeford, who was praised in November after he fatally shot the gunman who'd killed 26 people at a Texas church in Sutherland Springs.
In a telephone interview with NBC News, Willeford said he would “be honored to shake the hand" of Gaskill.
“He’s another good guy with a gun,” he said, repeating a phrase that is part of the NRA's mantra about armed citizens being the only thing "that can stop a bad guy with a gun."
Willeford is not likely to get any argument on the good guy part from Gaskill’s boss, Sheriff Tim Cameron, or Maryland Gov. Larry Hogan. Both have praised the 34-year-old “tough guy” for putting his own life on the line Tuesday.
“While it’s still tragic, he may have saved other people’s lives,” Hogan said of Gaskill in the aftermath of Tuesday’s shooting.
Gaskill has yet to make a public statement.
Willeford's brush with fame came after he pursued Texas church shooter Devin Patrick Kelly and shot him dead. He used a rifle similar to the Ruger AR-556 that Kelley used to commit the massacre.
It was later revealed that Willeford was a longtime NRA gun instructor — so the powerful gun lobby, which has been fighting attempts to ban such weapons, was quick to dub him as their kind of hero.
They did the same for Gaskill on Tuesday.
Willeford, who recently was the guest of Rep. Henry Cuellar, D-Tex., at the State of the Union address in January, has done only sporadic interview since the Nov. 5 tragedy that pulled him from obscurity.
His lawyer, Pamela Thompson of San Antonio, said that’s mostly been by design.
