After students reported that a 13-year-old at Ánimo Mae Jemison Charter Middle School in Willowbrook had threatened to shoot them, Sheriff’s deputies seized an AR-15 semi-automatic rifle, ammunition, a list of targets, and a drawing of the school’s layout when they served a search warrant at the student’s home Friday, the Los Angeles Times reports.
The student and an adult relative have been arrested, though police didn’t specify the adult’s role at a Friday morning press conference.
The deputies found the semi-automatic rifle, along with a high-capacity magazine, 100 rounds of ammunition, a “rudimentary hand-drawn map” of the school, and a list of names of students and staff members.
As an independent charter, Ánimo Mae Jemison does not have a Los Angeles School Police presence, Sheriff’s Department spokesman Rudy Perez said.
Though earlier reports stated that the AR-15 seized was an untraceable “ghost gun” assembled from parts of different weapons, Undersheriff Tim Murakami clarified that they were two separate incidents.
In the case of the ghost gun, deputies also took an individual into custody on suspicion of possessing and dealing firearms Friday. Murakami said that suspect had allegedly bought parts on the internet and that officers found, “a ghost gun—fully auto, silencers, body armor.”
In yet a third incident, Sheriff’s officials also arrested a student of Pete Knight High School in Palmdale after he allegedly made threats online. The student had been involved in a campus fight and later posted threats and a photo of a person holding a firearm, Sheriff Alex Villanueva said this morning.
These threats are part of a disturbing trend. Police stepped up their patrols around Charter Oak High School in Covina today after that school received a threat, and a student at Visalia’s Redwood High School was arrested Thursday after threatening to shoot his classmates.
The incidents come just a week after a 16-year-old at Saugus High School in Santa Clarita killed two fellow students, himself, and injured three others. The weapon in that mass shooting was an unregistered “kit gun.”
