The Great Mills shooting comes about five weeks after a massacre at a Florida high school left 14 students and three adult staff members dead and sparked a grassroots campaign for tougher laws on gun ownership.
St. Mary's County Sheriff Tim Cameron said during an afternoon press conference it's not yet known if Rollins was shot by the SRO. Authorities have not released his name.
Cameron initially said the 14-year-old student was shot by Rollins, but he later indicated that the exact circumstances were still unclear.
Nearly immediately, Davis was embraced by Florida shooting survivor Delaney Tarr, a student who has since told lawmakers they will be voted out of office if they fail to pass gun safety measures.
"This [Great Mills High School] armed school resource officer, you're not hearing anyone in #MSM talk about it because it disrupts their narrative", NRA spokeswoman Dana Loesch said in one of several tweets Tuesday.
Deputies say Rollins and the girl who was shot had a relationship in the past.
The 17-year-old shooter likely did not have legal authorization to possess the gun.
Gaskill responded to the scene in less than a minute, the sheriff said.
The shooter was identified as 17-year-old Austin Rollins, who died Tuesday. It also includes another $50 million annually to pay for school resource officers, counselors and technology.
This wasn't the first time Gaskill, who has been with the sheriff's office for six years, thwarted a potentially deadly situation.
It's the latest school shooting in a country still reeling from last month's attack in Parkland, Florida that killed 17.
The sheriff's office confirmed an incident at the school and urged parents in a Twitter post not to approach the campus.
