FRIENDSWOOD, Texas -- Two young teens are in custody after Friendswood police say officers found "disturbing images and statements that manifest Columbine ideations and a fixation on school shootings."

The teens, both Friendswood High School students, were taken to the Galveston County Jail and are charged with unlawful carrying weapons in a weapon free zone, police say.

According to Friendswood PD, the investigation began when a student made a report on Tuesday that a fellow 14-year old student allegedly had a handgun hidden in his binder. A search was conducted at the school, but no gun was found.

Later that evening, the uncle of the same 14-year old boy reported a theft of a firearm, police say. The gun was last seen in mid-October and was stolen from his Friendswood home. The uncle apparently knew his nephew was questioned about having a gun at school that day, according to police.

Later Tuesday night, school officials received information that there were pictures of the stolen firearm on Instagram and a possible location of the weapon was obtained. Investigators found the source of the post and they went to a home in the Polly Ranch subdivision where they were able to recover the stolen weapon at about 1:30 a.m.

During the investigation, the Instagram and Twitter accounts of two teen suspects were examined. These accounts allegedly contained the disturbing statements similar to Columbine, police say.

Friendswood PD took one juvenile into custody on Thursday. The second juvenile was taken into custody as well.

“Police officials urge parents to be aware of their children’s conduct on social media and to properly secure firearms in their residence,” the department stated in a press release.
