Stanford University officials investigating the drowning of a male student at a fraternity party have recommended punishment for Zeta Psi and harsher penalties for those who break liquor rules. An investigative committee found “substantial disregard” for fraternity and university rules during the party April 21 at Lake Lagunitas. The body of David Dunshee, 20, of Eugene, Ore., was recovered from the lake three days later. An autopsy revealed Dunshee had a blood alcohol level more than twice the legal limit after drinking large quantities of tequila. The investigators recommended temporary withdrawal of the recognition of the fraternity and advised the school to re-examine ways of enforcing its liquor policies.
