There's a developing story coming out of Maryland, where a Baltimore County high-school student was shot on the first day of the school year Monday.
Details are still scarce, but police say they have the shooter in custody and that the Perry Hall High School student was airlifted to a local hospital, the Associated Press reports. No official word yet on the student's condition, although local CBS affiliate WJZ-TV is reporting that he is in serious condition.
More unconfirmed details from WJZ-TV:
There are unconfirmed reports the shooting happened in the school cafeteria and the victim was shot in the back. Parents are telling Eyewitness News there may have been a threat on Facebook referencing the school, but there are no confirmed reports of that.
The AP describes Perry Hall as a "middle-class community along the Interstate 95 corridor, northeast of Baltimore city." We'll update with more when we can.
UPDATE, 1:45 p.m.: The 17-year-old male student is in critical condition at Maryland Shock Trauma Center, a spokeswoman at the hospital tells NBC News.
Local affiliate WBAL-TV, meanwhile, has more on the possible motive, saying that a student who reportedly witnessed the incident unfold said that the shooter was being teased and that he then left the cafeteria only to come back with a shotgun and open fire.
UPDATE 6:01 p.m.: AP with the latest: "Baltimore County Police Chief James Johnson said at a news conference that officers do not believe the victim, a 17-year-old male, was targeted by the shooter, a 15-year-old who is also a student at Perry Hall High School. A male suspect was taken into custody after the shooting, and police took the weapon, although police would not say what kind of gun it was." Read more here.
