The school are, according to KOAA:

  • Bergens
  • Blue Heron

Officials haven’t commented on the nature of the threats and no injuries have been reported.

Jefferson County Public Schools sent an e-mail to parents saying that all students and staff were safe.

This Saturday (Apr. 20) marks the 20-year anniversary of the Columbine High School massacre in which 12 students and one teacher were murdered by two seniors.
