REDDING, Calif. (AP) — The Latest on trash left behind at a California lake after an annual trip by fraternity and sorority members (all times local): 5:15 p.m. University of Oregon officials say they are investigating whether other campus fraternities and sororities were responsible for a trash-strewn mess at a California lake after one fraternity was suspended. Vice President for Student Life Robin Holmes said in a statement that the national fraternity, Lambda Chi Alpha, has suspended all the activities of its University of Oregon chapter. Holmes said the mess left at Slaughterhouse Island in Lake Shasta over the weekend was disgraceful.
