Family Sues Over Scientist's Cold War LSD Death Sons claim CIA killed their father in 1950s By Newser Editors and Wire Services Posted Nov 28, 2012 7:05 PM CST 15 comments Comments Photo illustration from Shutterstock. (Shutterstock) (Newser) – The sons of a Cold War scientist who plunged to his death in 1953 several days after unwittingly taking LSD in a CIA mind-control experiment sued the government today. They claim the CIA murdered their father, Frank Olson, by pushing him from a 13th-story window of a hotel and that he did not, as the CIA says, jump to his death. Sons Eric and Nils Olson of Frederick, Md., sought unspecified compensatory damages in the lawsuit filed in federal court. Olson was a bioweapons expert at Fort Detrick, the Army's biological weapons research center in Maryland. Their lawsuit claims the CIA killed Olson when he developed misgivings after witnessing interrogations in which they allege the CIA committed murder using biological agents Olson had developed. The CIA had a program in the 1950s and '60s called MK-ULTRA, which involved brainwashing and administering experimental drugs like LSD to unsuspecting individuals. The project was investigated by Congress in the 1970s. Olson consumed a drink laced with LSD by CIA agents on Nov. 19, 1953, the suit says. Later that month, after being taken to New York City purportedly for a "psychiatric" consultation, Olson plunged to his death. Click for AP's full story.
