Police officials in Hanover, N.H., still aren’t saying what they were looking for in a raid on a Dartmouth College fraternity house in June, but they concede that they didn’t find it. The police chief, Nicholas Giaccone, would not discuss the focus of the inquiry, according to the Associated Press, but said the case is now closed.

The raid drew widespread attention (The Chronicle, June 9) because the Dartmouth chapter of the fraternity, Alpha Delta, is believed to have been the inspiration for the 1978 movie Animal House.

The fraternity’s alumni adviser, John Engelman, said he had been told by a police captain that officers were looking for a videotape, alleged to have been made several years ago, of a Dartmouth woman engaged in sex with a member of the fraternity. Mr. Engelman said that, according to the woman’s account, the sex was consensual, but the videotaping was not. Such videotaping is a misdemeanor in New Hampshire, punishable by a fine of up to $2,000 or up to a year of jail time.

While the search failed to find the evidence it sought, it led to the unrelated arrests of two fraternity members on marijuana-possession charges.
