MIDDLETOWN, Conn. (AP) Three of four Wesleyan University students are due in court on drug charges related to about a dozen hospitalizations among people who took a party drug known as Molly.

Eric Lonergan, of Rio de Janeiro; Zachary Kramer, of Bethesda, Maryland; and Rama Agha Al Nakib, of Lutherville, Maryland, are due in Middletown Superior Court on Wednesday morning.

Police say Andrew Olson, of Atascadero, California, posted bond Tuesday and is due in court March 3.

The students were suspended from the university.

Eleven Wesleyan students, some of whom had attended a rave music show on Saturday night, received medical attention over the weekend. Police say two students were still being treated Tuesday.

Authorities from various agencies worked to identify the types of chemicals in the batch of Molly that caused the weekend overdoses.
