A Miami teen is facing charges after police said he hacked into his high school's computer system and altered four students' report cards.
Jose Bautista, 18, was arrested last week after giving his principal a written confession, police said.
Officials said Bautista charged students to have their grades changed, and then hacked into the school's grading system to do so.
Students who worked hard for their grades said they were disappointed.
"If that's what actually happened here, then, obviously, I think we are all disappointed in that," said student Brett Curtis.
Authorities said if Bautista is released from jail, he will be under house arrest and required to wear a GPS monitor.
If convicted, he could face up to 20 years in prison.
