Police say the fifth-grader, who is 10 years old, sent text messages about violence at his elementary school.

The sheriff's office said it took the threat seriously because of deadly Robb Elementary School shooting that happened last week in Uvalde, Texas. An 18-year-old gunman killed 21 people there.
