For the second time in two weeks an Anderson High School student has been sexually assaulted. The most recent crime happened on campus.
Friday morning an AISD police officer stood guard at the front door to Anderson High School in Northwest Austin.
Relatives of students say they want to see more police after two students were sexually assaulted in two weeks.
Danny Vasquez's cousin is a freshman at the school, "Way more actually because she's 15 and no way could I ever imagine that happening to her.”
Thursday school staff called parents and sent letters home alerting them to the fact that a student had been sexually assaulted on the campus.
"It's very scary for that to be happening here,” said Vasquez.
"We're surprised too. It's kind of horrifying,” said parent Kara Gross.
The event comes two weeks after police say another student was confronted upon her arrival to school, forced into an alley behind a shopping center sexually assaulted and strangled.
Austin police arrested Isaac Edward Sosa for the crime. He was charged with sexual assault and felony assault strangulation.
AISD police say they have identified everyone involved in the most recent incident and deemed the campus to be safe. But parents are still left wondering how it could've happened on school grounds.
"They have to preserve names for protection, but how did it happen? Where did it happen? Was it after school? Who was in charge,” asked Gross.
While those questions may remain unanswered due to the ongoing investigation, a spokesperson for the SAFE Alliance, a help center for sex assault victims, says this is a prime opportunity for parents to talk with their kids.
"Really communicate with your kids about who they're with and why they're hanging out with them and what healthy relationships look to them what they're seeing as other relationships and what to do if they're uncomfortable,” said spokesperson Victoria Berryhill.
According to the U.S. Department of Justice teens age 16-19 are three times more likely than the general population to be victims of rape or sex assault.
"Unfortunately teen violence and teen sex assault is very common and the only ways we can prevent that is teaching how to ask for consent and how to give consent so it's important to have those conversations with our kids as early as possible,” said Berryhill.
