Despite professor Kevin Mulcahy being placed on paid administrative leave Friday, his political science classes were still held this week. Mulcahy’s classes met with substitute instructors, said James Stoner, Department of Political Science chair. Stoner said he taught one of Mulcahy’s courses himself this week.Mulcahy has been at the University for 28 years and teaches several courses, including American government and American presidency topics. He teaches more than 80 students.A decision will be made next week whether to hire permanent substitutes for the semester, Stoner said. Until then, the current arrangement will continue.Mulcahy’s Sept. 4 arrest is leading to an investigative probe by the University. The Office of the Registrar and Human Resource Management refused to comment on the status of the probe.Mulcahy was placed on paid administrative leave, pending University review, after being booked into parish prison on charges of unauthorized entering of an inhabited dwelling last week.Last Friday, Mulcahy and English professor Eldon Birthwright were drinking outside Birthwright’s apartment when Mulcahy abruptly walked inside the apartment without Birthwright’s permission, according to a police affidavit.Mulcahy “suddenly became ill with diarrhea, experiencing an uncontrollable need to use the bathroom” and rushed through the unlocked door into Birthwright’s apartment to find the bathroom, Mulcahy’s lawyer, Drew Louviere said in an e-mail to The Daily Reveille.Mulcahy entered into the apartment and “began taking off his clothes while grabbing onto [Birthwright’s] housemate,” Birthwright said in an e-mail obtained by The Daily Reveille. He said he was able to “force him out with the assistance of a neighbor.”Birthwright held a butcher knife against Mulcahy’s throat and forced him out of the apartment, Louviere said.Birthwright contacted the Baton Rouge Police Department that night, and Mulcahy was arrested and booked into parish prison. Birthwright also said in the e-mail he “briefed the chair of Political Science” on Sunday morning.Mulcahy’s previous arrest in 2006 also led to an investigative probe by the University and his placement on paid administrative leave.Mulcahy was issued a misdemeanor summons Sept. 15, 2006, when a University student claimed Mulcahy followed him to his apartment as he walked home. Mulcahy was arrested and accused of being a peeping Tom, City Prosecutor Art Boudreaux said.After University officials reviewed the 2006 incident, Mulcahy was immediately reinstated, Louviere said. Prosecutors did not move forward with the case, and Mulcahy was not convicted then, but almost two years later, the prosecutor’s office said the case is still open. Boudreaux said he does not yet have a final plea arrangement.—-Contact Leslie Presnall at [email protected]
