Students sick of getting their lockers broken into and having their money disappear set up a cell phone camera to hopefully catch the crook in the act.
Deputies said the video showed the crook was Steven Simmons, 49, their PE teacher.
It's news that spread quickly at North Marion High School.
"There's videos going around and forwarded messages of his mug shot, and it's crazy," said Shelby Revels, a North Marion High student.
Deputies said at first Simmons denied going into the lockers.
However, when confronted with the video, they said he confessed to stealing money from students for years.
This year, it totaled around $400.
