The owner of the trailer had offered $1,000, on Craigslist, to have it removed.
35-year-old Derek Conley allegedly responded to the ad. He removed half of the trailer on Saturday and left it at the school.
Late Monday night, Conley returned to remove the second half of the trailer and deputies arrested him.
Conley is charged with second-degree criminal mischief, offensive littering, and an outstanding probation violation warrant for felon in possession of a firearm. He is currently being lodged at the Washington County Jail.
The dumped mobile home was initially towed from the school and stored on City of Cornelius City Works property. It was transported back to the original seller.
