HOUSTON, Texas (KTRK) -- Threats were allegedly posted to social media back on Aug. 3 when Hector Fernando Fonseca was at Bush Intercontinental Airport waiting to get on a flight.
Fonseca is now facing serious charges over Snapchat posts.
Humble ISD has confirmed the teenager is a junior at Atascocita High School, and he went before a judge who set a bond of $15,000.
Documents state he was with his father, both getting on a United flight from Houston to Guatemala.
While sitting in the airport, the teen allegedly posted a photo on Snapchat of himself with the caption "blow this (expletive) up," and then another photo taken on the airplane.
A representative from SnapChat emailed the posts to the FBI on Aug. 4 and then HPD got involved, arresting the teen when he returned on Aug. 10.
"People don't think before they post things, and they should start doing that a lot more," a student said.
