Madison County Prosecutor Steve Pronai will meet with officials from the University of Dayton this week to discuss possible criminal charges against 80 students who allegedly vandalized a Choctaw Lake mini-mart in a drunken rampage. A sheriff’s report said two busloads of students, both men and women, stopped at Lake Side Plaza, 3180 Old Columbus Road, around 5 p.m., following an outing to Columbus. All were intoxicated. At least 33 were under the legal drinking age. All were associated in some way with Sigma Chi fraternity.
