The Austin Police Department bomb squad picked up the package, which was a long cylinder that Hutto police X-rayed and deemed safe. School officials expect the scene to be cleared shortly.
Hutto Independent School District spokeswoman Emily Grobe said the package was found at the entrance of the Ninth Grade Center. That's when all students in the Ninth Grade Center moved to the auditorium.
Parents are being encouraged not to pick up their students, reassuring parents that their children are safe.
In the meantime, authorities at the school are trying to figure out where the package came from.
This comes on a day where much of the nation is on edge following the deadly bombings in Boston.
Two bombs blew up seconds apart Monday at the finish line of one of the world's most storied races, tearing off limbs and leaving the streets spattered with blood and strewn with broken glass. Three people were killed, including an 8-year-old boy, and more than 170 were wounded.
And the package situation near the Hutto campus is one Austin Police Chief Art Acevedo addressed hours before the incident happened -- speaking to the need for heightened awareness and vigilance among the community.
"You don't leave a bag at an airport, and you should not do that in our races," said Acevedo during KXAN News Today. "And I think we're going to have to work really hard to change the mindset of our folks we're involved with."
Acevedo referred to finish lines at marathons and how they have to be treated as crowds in an airport, where there's a lot of congregation of people.
"We don't have enough officers to take care of everything at once," said Acevedo. "But if everyone's engaged, everyone's aware, everyone takes the time to be the eyes and ears of their neighbors, their fellow runners, the police department, we'll be much safer."
