A West Michigan educator may face drug possession charges for allegedly planting marijuana in a student's locker.

Pat Conroy is the assistant principal at South Haven High School, near Grand Rapids.

Earlier this month, he told police he put the drugs in the locker because he suspected the student was a drug dealer, and wanted the boy expelled.

Conroy's plan failed because a drug-sniffing dog didn't find any marijuana during a school search.

But police later searched Conroy's office and found the suspected marijuana.
