Blaine Gaskill, a St. Mary's County Sheriff's Office deputy with SWAT training who had been positioned at Great Mills High School since the beginning of the school year, immediately responded after being alerted of the shooting, officials said. She was wounded after a 17-year-old classmate opened fire just before 8 a.m.in a school hallway with a Glock semiautomatic handgun.
Two students - the girl, who is 16, and a 14-year-old boy - were taken to hospitals, where the girl was listed in stable condition and the boy in good condition, according to hospital statements.
But if Gaskill's shot stopped him, the deputy would be only the second resource officer to gun down an active school shooter since the Columbine High School massacre in 1999, according to a year-long Washington Post analysis of dozens of school shootings.
The shooter died and his two victims are seriously ill hospital following the early morning bloodbath today at Great Mills High School in Maryland, US.
Sheriff Cameron told reporters at an afternoon press briefing that Deputy Gaskill, a six-year veteran of the force who is in his first year at Great Mills High School, was able to contain the situation within 1 minute of the time the initial shot was sacked. This weekend, students across the country plan an anti-gun violence march on the nation's capital.
Before today there had been 16 confirmed school shootings in the U.S. so far this year, according to CNN.
Gaskill was not injured, Cameron said. Julie Yingling said there were several injuries but she didn't know how many or the severity of the injuries.
Tracey Harms's son is a sophomore at Great Mills.

He has also spoken about the need to avoid another arms race, despite using his pre-election address to showcase new Russian arms. He said that during their hoped-for meeting the two men would likely discuss Ukraine, Syria and North Korea, among other things.
Gaskill's interaction on Monday with the deceased gunman, 17-year-old Austin Wyatt Rollins, wasn't the first time he came face-to-face with a firearm.
"The police came and responded really quickly", Freese said.
Great Mills High School has an enrollment of just over 1,500 students, about 56% of them minority students. One message said, "Lord, help the parents of the shooter to find hope and peace in you".
There's been a lot of debate lately about whether more guns in schools are the answer.
A student who said his name was Jonathan Freese said in a telephone interview on CNN that he had been on lockdown with classmates for almost an hour, but he did not hear gunshots himself.
She added, "We are resolved to provide all the support and comfort we can to our colleagues and neighbors in the Great Mills community while we work together towards a day when no school community ever has to experience this type of tragedy". Sirens can also be heard in the background.
Democratic Rep. Steny Hoyer praised the first responders, saying the officer at the school "answered the call this morning with swiftness, professionalism, and courage".
With three weeks left in the session, Hogan said, "It's outrageous that we haven't taken action yet on something as important as school safety".
