Three people were injured in a shooting at Great Mills High School in southern Maryland on Tuesday morning, according to a county spokesman.
No fatalities have been confirmed in the shooting at the school at 21130 Great Mills Road, which happened just before 8 a.m., county spokesman Tony Jones said from the emergency operations center. Two of the victims are students, Jones said. None of the victims' conditions were released.
The St. Mary's County school is on lockdown and students are being evacuated, Jones said. It's unclear where in the school the shooting happened.
By 10 a.m., students were being evacuated from Great Mills. "The building is orderly and the Sheriff's Office is conducting an investigation," St. Mary's County Public Schools said on Twitter.
Parents are being asked to meet their children at a reunification site at Forrest Career Technnical Center in Leonardtown. Details about any injuries or the person who fired shots was not immediately available.
"There has been an incident at Great Mills High School," the department tweeted. "Parents please DO NOT respond to the school."
Senior Terrence Rhames was standing with his friends outside their first-period class around 8 a.m. when he heard a shot. He said he knew instantly what the loud crack meant.
He started running, heading to a first-floor bathroom before thinking to himself, "This is a dead end." He turned to instead sprint toward the nearest exit. Out of the corner of his eye, Rhames said, he saw a girl fall.
"I just thank god I'm safe," said Rhames, 18. "I just want to know who did it and who got injured."
Great Mills, which enrolls about 1,600 students, is about 90 miles outside of Baltimore.
St. Mary's Ryken High School, a private school about 15 minutes northwest of Great Mills, went into lockdown around 9 a.m., according to Brad Chamberlain, dean of academics.
"We're getting conflicting reports," Chamberlain said.
The incident comes just over a month after a deadly rampage in a Florida high school. Seventeen people died in the Marjory Stoneman Douglas High School shooting, catalyzing a national conversation about gun violence in schools.
This weekend, thousands of students are expected to flood Washington for the "March for Our Lives," a nationwide protest to demand an end to mass shooting in schools.
Gov. Larry Hogan said he was "closely monitoring" the situation at Great Mills.
Maryland State Police "is in touch with local law enforcement and ready to provide support. Our prayers are with students, school personnel, and first responders," Hogan tweeted.
Maryland State Police troopers, agents from the Bureau of Alcohol, Tobacco, Firearms and Explosive's Hyattsville offices, and FBI agents are also assisting.
