At Lake Travis High School Friday morning, it was drop off time as usual, except for the stepped up police presence. Thursday, the superintendent sent a letter to parents to notify them about a threat discovered on campus last week. The words, "There will be blood, 4-26-13" were found written in pencil on the bottom of a stool in the library of the high school campus.
"We're working with law enforcement officials to figure out how this occurred and we want to make sure folks know we're serious and it is a disruption to our normal routine and those folks responsible face discipline," Lake Travis ISD spokesman Marco Alvarado told FOX 7 on Thursday.
While the district urged parents to send their kids to school Friday, many chose not to.
"We made the decision together as a family and just felt like it was easier to keep everybody home, keep everybody safe," said Lake Travis High School parent Patrick Perrin.
Another Lake Travis ISD parent Wendy Jenks said, "They were worried, they were concerned about going to school and just that concern made me think, why stress them out and make them go?"
The decision to keep their kids home was also made due to recent senseless acts of violence in the U.S.
"I just felt in light of the situation that has happened in America recently I just felt like I didn't want to make it a non-issue with my children to protect them so just real simple, kept them at home," Perrin told FOX 7.
While on their lunch break, a group of Lake Travis High School seniors told us they were confident in the way the district handled the threat and that's why they decided to go to school. It was kind of scary at first," said Jerry Benson. "My reasoning was it's just so safe at school with all the cops and it's not a big deal."
Police are investigating the threat and trying to determine who wrote it. According to district officials, there was a drop in attendance Friday.
