The following message was sent at roughly 11:55 p.m. Monday, Jan. 30, to all Northwest ISD families and staff from Superintendent Ryder Warren, Ed.D. A timeline of other updates can be seen below the message. 

Many are aware of the challenges we had today at Byron Nelson High School. The most important news to report tonight is that the building and the grounds of Byron Nelson High School have been given the “all clear” by the police departments working this issue, so all vehicles can be released to their owners, and the campus will be ready for school in the morning.

I also want to give everyone as much detail as we can right now, and there will be more information releases to follow tomorrow. The following are the facts that we know at this time:

  1. A bomb threat was made against Byron Nelson High School on Monday afternoon. The first message indicated the threatening individual was inside the building, so we immediately went into an internal lockdown.
  2. Many different police agencies responded, including a bomb squad.
  3. NISD was instructed by law enforcement to keep students in lockdown until the building was thoroughly swept by police.
  4. Students and staff were released a little after 6 p.m. Monday to go home; however, law enforcement would not release any vehicles from the premises until the bomb squad has given the “all clear” for all vehicles on site.
  5. NISD will have the Byron Nelson counseling staff plus additional campus counselors on hand at the school tomorrow if any students, staff, or parents need any extra support.
  6. NISD will work hand in hand with local and regional law enforcement to identify the perpetrator(s) of this crime.

As the superintendent of this district, know that we are very sorry our kids, staff, and parents had to deal with this today. I would also like to sincerely thank all of our law enforcement partners, our staff members, and our students and parents for such great behavior through all of this. Byron Nelson High School is a special campus, and the way all handled this stressful day showed that specialness.

Again – we are cleared for a regular school day tomorrow, and my heartfelt “Thank You” goes out to all those involved for their extraordinary efforts today.


Ryder Warren, Superintendent of Schools

Police have determined it is safe for students to exit Byron Nelson High School systematically – top floor down. Students with special needs will be released first. All students will be escorted to Medlin Middle School across the street. Bobcat Boulevard will be closed down to traffic except for buses. Buses will be lined up along Bobcat Boulevard. There will be a bus route number in multiple windows of the bus. Bobcat Boulevard will be opened once buses leave. There will be staff assisting students in finding their bus.

Parents may pick up their children at Medlin Middle School. Students who drove a vehicle to school need to leave their car at the campus. At this time, it is not determined by police at what time students can get their cars. Northwest ISD will notify families when students may get their car. Police have requested students to leave their backpacks in the building.

Northwest ISD is fully cooperating with local law enforcement to find out who is responsible for this. All students remained safe during this time. We appreciate the support from our parent communities. Safety drills are practiced throughout the year should this type of situation occur so that students and staff are prepared.
