Hanover Police after investigating Sigma Alpha Epsilon fraternity and Sigma Delta sorority will not file any charges against the houses.
Hanover Police Detective Rick Paulsen said the police are currently investigating several other Greek houses, but declined to name them.
In the SAE and Sigma Delt case, police were looking into the arrests of three underaged, non-Dartmouth students on July 21 for possession of alcohol.
Paulsen said the investigation is closed because of "the unavailability of the witnesses."
He said three students arrested are now "all over the country" and it is too much of a hassle to have them return to Hanover.
"Basically this case is going to be closed because the county attorney is not going to fly them up here," he said.
Sigma Delt President Lauren Currie '96 said Sigma Delt would continue to comply with state and College alcohol guidelines.
Paulsen said he expected the town to file charges against at least one of the "other" houses within the next two months.
