Burleson County Sheriff, Dale Stroud, says he believes what prompted a lock down at Caldwell High School yesterday afternoon was a prank.
Three messages were discovered at the high school and law enforcement believes more than one person left the suicide-type messages.
Prank or not, it did scare some students and parents.
"That was my first thought, I was like, I've got to get my child," said Tiffany Lohse, a Caldwell ISD parent.
She says she couldn't drive fast enough to Caldwell High School to pick up her freshman daughter.
Lohse said, "They came on the announcements and said....the kids that were in the hallways, or whatever, needed to get to class, if they were in the bathroom they needed to go to the office and they told all the teachers, they're on lock down."
Burleson County Sheriff, Dale Stroud, believes more than one person is responsible for leaving three messages, in different areas of campus, threatening to harm themselves on Wednesday.
"I'm kind of scared, a little, that something might happen today," admitted Caldwell High School student, Tyler Shupak.
Caldwell High School student, Dominique Oertel said, "I think the lower classmen were like the ones that were like, scared and like freaking out, saying they're not coming to school today."
Some parents say the automated alert system used by the school district didn't warn them early enough about their children.
"I had been standing there probably ten minutes waiting for her to come out and that's when I got the alert," said Lohse.
Text messages, phone calls, even emails, parents were alerted three different ways and they determine in what order they're informed.
Lohse said, "I had never felt so relieved then when I saw my daughter come out of that school and she was not hurt."
Law enforcement believes the messages are pranks.
Serious or not, the threats will have major consequences.
Several students have been questioned by school officials and sheriff's deputies.
Caldwell's superintendent says no one has been taken into custody.
