Skokie, Ill. ? Two parents were charged Wednesday with supplying alcohol to students at a suburban Chicago high school who participated in a brutal hazing incident captured on videotape.

Christine Neal, 49, was charged with delivery of alcohol to a minor for buying three kegs of beer, two of which were found at the park where the hazing took place, prosecutors said. Marcy Spiwak, 49, was charged with allowing her home to be used for underaged drinking.

Neal is the mother of student Dominic Vargas, 18, who was charged with unlawful possession of alcohol by a minor. Authorities said Vargas brought the kegs to the May 4 “powder puff” event where junior girls were brutally hazed by seniors.

Videotape of the event shows juniors from Glenbrook North High School being covered with mud, paint, feces and garbage as onlookers, some hoisting beer cups, cheered.

Neal, who was arrested Tuesday, and Vargas were released on $100 bond each. An arrest warrant had been issued for Spiwak, who is the mother of a junior girl who was at the hazing.

All charges carry a maximum punishment of a year in jail; the adults also face fines of at least $500.

Vargas was among the 15 students who last week were charged with misdemeanor battery in the incident in suburban Northbrook. Some 31 students — all but three of them girls — have received 10-day suspensions.

Some juniors who were hazing victims also have been suspended from the prom and other extracurricular activities and could face further punishment. School officials would not say how many were disciplined.

The school board will meet Sunday to decide whether to expel seniors suspended after the hazing.
