Columbia, Mo. ? The number of University of Missouri students referred for suspected alcohol violations doubled from 2008 to 2009, but officials said the numbers are known to fluctuate and part of the increase might be the result of better reporting on campus.

The number of students referred on suspicion of violating alcohol policies went from 430 in 2008 to 883 in 2009, according to the latest report on the issue. In 2007, 631 students were referred.

Kristen Temple, associate director of Residential Life, stressed that not all the referred students were found guilty of alcohol violations.

Three new residential halls opened in 2009, which meant more students were living on campus. The new halls have some suite-like rooms, where students might be more likely to try to sneak alcohol in because they’re more private, Temple said.

Students found guilty of alcohol violations typically are referred to the Wellness Resource Center for alcohol education. A second violation triggers probation and a letter to parents. Students guilty of three violations are temporarily kicked out of campus housing.
