Here is what you need to know:

1. Police Have Identified the Suspect as William Atchison

Police say that there was one suspect, 21-year-old William Atchison. He entered the building just after the school day commenced and opened fire.

Police have confirmed that Atchison committed suicide at the scene.

San Juan County Sheriff Ken Christesen said that Atchison had a detailed plan for holding a classroom hostage, which investigators discovered on a flash drive on his person. Christesen described the attack as a “cowardly act” that was designed to “create as much carnage” as possible.

Atchison had reportedly dressed like a student in order to infiltrate the school campus, a fact that had initially led investigators to believe that the suspect was a student at Aztec High School.

2. Two Students Were Shot & Killed

Police confirmed that two students were shot and killed in this morning’s incident. Authorities have identified these two students as Casey Marquez and Francisco Fernandez.

“It’s tragic when our children are harmed in violent ways, especially on school campuses. We express our condolences to those families who have been harmed. Our prayers go out to all those affected by this tragedy, and everyone throughout San Juan County. We are asking for prayers for these families,” President Russell Begaye on The Navajo Nation said in a press release.

Bloomfield Police Department shared the following message on Facebook this morning:

“We are aware that there is an active shooter at Aztec High School. We do have officers located at all of the schools in Bloomfield and they are all on lock down. Parents are advised to please stay away from all of the schools until further notice.”
