MONTGOMERY COUNTY, Md. — *Editor's Note: WUSA9's policy is not to name juveniles charged with crimes unless they are charged as an adult, as is the case here.
A 17-year-old student at Colonel Magruder High School is now being held without bond in a juvenile facility after a 15-year-old sophomore was found shot in the school bathroom Friday.
Police say that the teen boys had an ongoing argument, and during a bond hearing Monday, prosecutors alleged that Steven Alston Jr., 17, planned to settle it in the bathroom.
Police believe other students possibly watched and live-tweeted the shooting, but failed to tell police or school staff.
According to the prosecutor, multiple witnesses said they saw Alston pull a loaded 9mm handgun from his waistband and point it at the victim's head. The victim then tried to push the gun away and he was shot in the pelvis.
Police are still working to identify who was in the bathroom at the time of the shooting.
The prosecutor says Alston dismantled the gun and went back to class. Police say he was eventually found sheltering in place with other students, with a gun magazine with nine more rounds shoved in his sock.

A privately manufactured firearm, also known as a ghost gun, was found inside the school, police said. The prosecutor says Alston bought the ghost gun online in parts and assembled it with a friend.
The public defender argued that Alston should be allowed to stay with his mother under 24-hour home detention due to his age and lack of a record.
The judge, Zuberi Williams, rejected the argument.
"He's a danger to this community," the prosecutor said.
Due to a new state law designed to protect juvenile defendants, State's Attorney John McCarthy couldn't talk about the new details released in the case outside of the courtroom.
"Guns will not be tolerated," McCarthy said. "There will be profound consequences for anyone who brings a gun into our schools."
Alston is being charged as an adult with attempted second-degree murder, first-degree assault, use of a firearm in the commission of a felony/violent crime, possession of a dangerous weapon on school property and possession of a firearm by a minor.
The 10th grader who was shot is still hospitalized in critical condition. As of Saturday morning, the student was out of surgery and expected to survive, according to Montgomery County Officer Carlos Cortes.
Dr. Monifa McKnight, Interim Superintendent of Schools, said Monday during a press conference that the victim's condition is still "very, very serious."
Jones also said that the victim did not share initially who shot him, or that he was shot at all. Jones explained that the situation where victims refrain from sharing information is not uncommon, however, it hinders police from protecting the community.
"We have to have a real conversation with our young people about, there is a place for social media," Montgomery County Chief of Police Marcus Jones said during the conference. "It is wiser to get the help started that [a victim] needs versus being the superstar on Twitter for the day."
McKnight said Magruder's second semester begins Tuesday. The first day back has now been designated as a half-day so that students have time to access mental health resources on campus to deal with the incident. Enhanced police presence will also be on school grounds.
She also added that any student still dealing with mental health impacts from what occurred can receive an excused absence in the coming days. Counselors, psychologists and increased staff will also be present to support students.
"This shockwave was felt by every single member of the Montgomery County community," Dr. McKnight said.
She went on to add that the district is evaluating all safety and security procedures, as well as ways to support students in learning how to interact appropriately with peers and manage conflict resolution after facing increased isolation during the pandemic.
