Two men burglarized the Orange County School District's storage yard a total of 61 times and stole more than 100,000 pounds of scrap metal worth $476,000, deputies said.
Investigators said the men sold the metal at an Orlando scrap yard for 10 percent of its value. Detectives said that yard then made its own $30,000 profit selling the scrap to another yard in Tampa.
The owner of the Orlando yard told WESH-TV in Orlando he did not know the metal was stolen.
Otis Jackson, 54, and Raymond Lindsey, 47, face multiple charges related to burglary, grand theft and stolen property.
The burglaries occurred over 21 months, deputies said. Lindsay broke in 57 times and Jackson 24 times, investigators said. The intruders cut through a chain-link fence to gain entry, investigators said.
The stolen items included more than 250 sets of metal ramps used by the disabled to access portable classrooms, officials said.
