Following a threat found written on the wall in a girl's bathroom, attendance was down at Frontier High School.
Many Students left early from school or stayed home all together.
"You know, even if it's just a hoax you still have it in the back of your mind, what if?" said Blanca Gutierrez, a parent of a student who attends FHS.
Lisa Krch, with Kern High School District said the threat was discovered in the late afternoon Monday inside one of the girls restrooms on campus.
The Kern High School District Police Department determined the threat was not credible, but KHSD still had extra security in place at the high school Tuesday. Some students said the extra security and knowing officials did not think the threat was credible made them feel more secure.
"They had a lot of extra security, they had like seven cop cars here so I just felt safe," said senior student, Simar Singh.
FHS tweeted to parents early Tuesday morning, "Admin & law enforcement are aware of a threat from 3/7. We do not believe it to be credible. Additional security will be on campus today."
Krch said around 8 Tuesday morning an automated phone call also went out to all parents, alerting them of the threat and again telling them the threat was not credible.
Freedom Middle School also sent out an email to parents telling them their students were safe.
Students are also dealing with the death of a fellow classmate, Jacob Briones, who took his life Friday night. Extra grief counselors have been on hand to help students and staff cope and students said all the threat added to the ongoing issues.
"It's kind of sad because we have all of what's going on with our fellow student who passed away," said Jose Garcia, a senior at FHS. "Now the school shooting. Like who would do that all in one day? It's pretty frustrating."
A similar threat was made at Golden Valley High School last week. Officials said that threat was also not credible.
Official said they will continue to investigate who made the threat and make sure they are punished to the full extent of the law.
