According to a message on the St. Mary's Public Schools website, Great Mills High School is on lockdown after a shooting on Tuesday morning. While the district is reporting that the situation has been contained, little else is known about the shooter, any victims or fatalities, or whether the perpetrator is at-large or in custody.
CNN reported that special agents from the Alcohol Tobacco and Firearms (ATF) office in Baltimore have been dispatched to the scene. One of the students at Great Mills told CNN that police are doing a full sweep of the school and then the students will be escorted off the grounds.
The school district tweeted that the Sheriff's office has responded to the incident and will offer more information after an assessment of the situation has been conducted. Parents and guardians have been instructed to reunify with the students at nearby Leonardtown High School.
Update @ 11:48 a.m. Eastern: The gunman and two students have been injured in the Maryland school shooting that took place on Tuesday morning. USA Today reported that a male Great Hills High School student opened fire on a female classmate in the hallway shortly after classes began. St. Mary's County Sheriff Tim Cameron also confirmed that a male student was struck by the gunfire.
A school resource office exchanged shots with the assailant and is believed to have wounded him, which ended the attack. There were no other injuries sustained, according to Cameron.
The outlet also reported that some time over the last few weeks, rumors of a possible shooting were investigated. No evidence of a credible threat was found, and it is unclear that there is any connection between that case and Tuesday's incident.Update @ 1:18 p.m. Eastern: St. Mary's County Sheriff Tim Cameron has confirmed that at 10:41 a.m. local time, the shooter was pronounced dead at Charles Regional Medical Center. One of the injured students, a 14-year-old male, is in stable condition at MedStar St. Mary's Hospital while the 16-year-old female student has been listed in critical condition at the University of Maryland Prince George's Hospital Center.
The school resource officer who was assigned to the campus reportedly fired a single round, striking the shooter. Cameron said that the student shot one round at the officer. That officer sustained no injuries. The sheriff said that his officers are prepared to confront school shooters, but would rather not have to do so.
"This is what we train for. This is what we prepare for and this is what we pray we never have to do," Cameron said. "And on this day we realized our worst nightmare that our greatest asset -- our children -- were attacked in a bastion of safety and security, one of our schools."
