Students have been evacuated to an enclosed area on the baseball and football fields. Water is being provided to students and staff as needed.

**Update -  After 11:00 a.m. - The investigation continues.  We have been informed that a student suspect is in custody.

Approximately 12:00 p.m. - The bomb squad is at Seven Lakes High School investigating. Students who may have to use the restroom are being transported by Katy ISD's school buses to the junior high at this time. We still do not plan to dismiss students until we receive further information.

Parents of students who already have permission to leave school for previously scheduled appointments are advised to email the school nurse.

Email SLHS Nurse

The nurse will arrange for the pick-up of the student.​

Approximately 12:45 p.m. - The students that were previously evacuated to the baseball and football fields are being moved to the Seven Lakes Junior High stadium, and are being released today at 1:30 p.m.

Students may be picked up by a parent or they may walk home. Students who do not have transportation will be provided Katy ISD bus transportation. Students who drove to school and currently have the keys in their possession may leave after their car has been cleared to go. Students with car keys in the building, or bikes near the building, are not allowed to retrieve them at this time.

Parents are being asked to pick up their students at Seven Lakes Junior High. All official after-school activities have been canceled.

Approximately 1:25 p.m. - All Seven Lakes High School students have been transported from the high school stadium to Seven Lakes Junior High School. Parents who are picking up students can now go to the junior high.

Again, students who drove to school and have access to their keys will only be allowed to remove their car from the parking lot after they have been given clearance by authorities. Please know that this may take some time. It is recommended that walkers walk home, and students whose parents can pick them up may come get them. All other students who normally take the bus to school will be provided bus transportation, as well as students who have no means of transportation.


Approximately 2:00 p.m. - The investigation continues at Seven Lakes High School. We have been informed that this could take a significant amount of time, as authorities must search the entire building. At this time, it is anticipated that school will resume tomorrow on its normal bell schedule.


After 4:00 p.m.-  This evening we were informed by the authorities that the high school building had been cleared and is safe for students to return. A student was taken into custody, and we are told that charges are pending. You should also be aware that one device, a zip gun which is any device altered to propel an object designed to cause harm, was found in the building. After a thorough search of the building, and examination of the device, the authorities informed us that the device had been secured and the building was cleared.

Also, so you're aware, this morning the high school had a regularly scheduled fire drill at 10:05 a.m. Students were returned to the building following that drill. Shortly after the regularly scheduled fire drill, we learned about the security threat. The students were then evacuated a second time. The fire drill and the evacuation related to the security threat were unrelated.

We know that many students left personal items in classrooms and open spaces throughout the school when it was evacuated earlier today. Classrooms and the building will be securely locked this evening. In the morning, administrators will be posted in open spaces where personal items may have been left by students. These administrators will monitor the retrieval of those items as students arrive.

Tomorrow, school will resume on its normal bell schedule. All SLHS students, including Miller and late arrival students, are asked to report to fourth period homeroom first thing in the morning. The regular school day will resume after fourth period homeroom. Quizzes and tests scheduled for tomorrow are postponed. Students should check with their teacher for an update on the quiz and test schedules.

Approximately 6:20 p.m. - This is a follow up to the message distributed around 4:55 p.m. today concerning the outcome of today's ongoing investigation at Seven Lakes High School.  We have been informed that the suspect had a firearm in the trunk of the vehicle he drove to school today.  The firearm was at no point removed by the suspect from the vehicle.  Again, the suspect is in custody and the school building has been cleared.

School will resume on its regular bell schedule tomorrow.  All SLHS students, including Miller and late arrival students, are asked to report to fourth period homeroom first thing in the morning. The regular school day will resume after fourth period homeroom. Quizzes and tests scheduled for tomorrow are postponed. Students should check with their teacher for an update on the quiz and test schedules.

Approximately 9:30 p.m. - In light of the events that took place today at Seven Lakes High School, it is important for parents to know what measures the District has in place to help ensure that campuses are safe. In Katy ISD, this is one of our top priorities.

Katy ISD has established plans and procedures in place to address emergency situations that a campus or the District may face. The District's School Safety Task Force, which includes representatives from each campus, as well as from local EMS, fire, and law enforcement, reviews these plans annually. In addition, an emergency response guide is located in every classroom and is accessible from the desktop of every staff computer in the District.

In recent years, Katy ISD has also upgraded many of our facilities with entry vestibules to help control access to our campuses and have established procedures for all campus visitors. We also provide training to our campus staff to reinforce proper procedures with regard to keeping doors locked, questioning suspicious individuals and proper response procedures should an intruder make their way on campus.

Finally, the District would like to stress the important role we all have in keeping our students and schools safe. Students are often the first line of defense when it comes to keeping our schools safe, as they often have first-hand knowledge about what their classmates are doing. Please take this time to talk to your children about reporting potential threats to the proper authorities.

The safety and security of students and staff members on our campuses is of the highest priority. For more information and to view a list of frequently asked questions in regards to campus security, click here.
