DES MOINES, Iowa — Drake University police say security camera footage helped them discover that two racist notes sent to students were a hoax.

Drake freshman Kissie Ram reported receiving a threatening note in her dorm room last month. It was the second time a Drake student had reported getting such a letter.

Police say they placed cameras near Ram’s room after she reported the first note. Those cameras never saw anyone place the second letter.

Ram is charged with filing a false report and could face expulsion from Drake University.
