Explosive docs reveal finals days of scientist who mysteriously died during CIA mind control program MKUltra

The last days and hours of a CIA scientist working in the secretive mind-controlling 'MKUltra' program have been revealed for the first time since he died in 1953.

Dr Frank Olson, a biological warfare scientist, was covertly dosed with LSD at a meeting and died nine days later after falling out of his hotel room in New York City, which was declared a suicide - although some people believe he was murdered.

Now, a newly declassified account from Dr Olson's boss and former head of the Special Operations Division of the Army Chemical Corps has provided a firsthand account of the final moments of the scientist's life.

Vincent Ruwet wrote that following a meeting on November 19, 1953, when the scientist was drugged, Dr Olson appeared agitated compared to his usual social, 'life of the party' behavior.

In the days that followed, Dr Olson became paranoid, barely ate and even disappeared into the night to toss out his wallet, identification badge and money cause he be believed Ruwet asked him to. 

'After about an hour of discussion it became apparent to me that Dr Olson needed psychiatric attention,' Ruwet wrote.

Dr Olson was set to fly out to a mental facility on November 27, telling Ruwet he would see him in the morning to catch the plane.

'At approximately 2:45am Sat. Nov. 28th, 1953, I received a call with from Dr [Sidney] Gottlieb with a message that Dr. Olson had died,' Ruwet's statement concluded.

Dr Olson's body was found outside the Statler Hotel where he was staying on the 13th floor. 

His family was not allowed to see his body, instead being told he had suffered significant facial injuries in the fall and that he had killed himself by jumping. 

However, it was confirmed that he did have LSD in his system at the time of death. 

In 1994, still uneasy with the narrative he'd been given, Dr Olson's oldest son had his father's body exhumed. 

The pathologist ruled that Dr Olson did not suffer disfiguring facial injuries, as the family had been told, and that he had an injury on his head which was consistent with him being murdered in his room and then thrown from the window. 

The CIA's MkUltra program, conducted from 1953 to 1964, aimed at developing procedures and drugs that could be used during interrogations, weakening individuals and forcing confessions through brainwashing and psychological torture.

A CIA spokesperson told DailyMail.com: 'The MKULTRA program ran from 1953 until the lack of productive results and ethical concerns about unwitting testing led to its cessation in 1963. 

'CIA is committed to transparency regarding this chapter of its history, including by declassifying information on the programs and making it publicly available on CIA.gov.'

Ruwet's firsthand account was part of a trove of documents from the project that were declassified in December, detailing Dr Olson's state of mind during and in the days following the Deep Creek Lake experiment.

That was when Dr Olson was slipped the drug, leading to him on a downward spiral for nine days.

Ruwet's statement, dated December 1, 1953, begins with him describing Dr Olson's personality before the Deep Creek Lake experiment on November 19.

Deep Creek Lake, located in Maryland was a location of a cottage the CIA used as a hideaway and likely conducted mind-controlling experiments at the site. 

'His personality was that almost of an extrovert,' he wrote. 'He liked a practical joke, did not carry it to excess.

'Socially, he was very popular, 'life of the party' type. He was the first one on hand to assist anyone who might have troubles either professionally or personally.'

The experiment took place on a Thursday and Ruwet and Dr Olson met for breakfast the next morning. 

Dr Olson appeared agitated as they sat down to eat, but Ruwet 'did not consider this to be abnormal under the circumstances' of just completing a MKUltra experiment.

On November 23, Dr Olson met with Ruwet to ask if he should be fired or if he should quit.

Ruwet was 'taken a-back' by the comments, and that is when the scientist's behavior took a turn for the worst.

'I saw him Tuesday, 24 November, 1953, when he again was waiting for me in my office when I came to work at about 7:30am,' stated Ruwet.

'He appeared greatly agitated an in his own words, 'all mixed up.' He said he felt that he was not competent, that he had done something wrong.'

Ruwet tried to comfort Dr Olson, but 'after an hour of discussions it became apparent to [him] that Dr Olsent needed psychiatric attention.'

The scientist agreed to seek help, working with Dr Robert Lashbrook to arrange a meeting with a psychiatrist in New York and a stay at a mental facility in Maryland.

Dr Olson and Ruwet hopped on a plane to New York that day, but the scientist 'was very anxious and had the feeling that someone was out to get him' during the flight.

They met with a psychiatrist, but the Dr Olson became too suspicious and agitated that the meeting was cut short. 

And the bizarre behavior continued when Dr Olson and Ruwet watched a Broadway show, 'Me and Juliet,' at 8:30pm.

'Dr Olson appeared to get upset during the first act and at intermission he was highly agitated and state that he knew that people were outside waiting to arrest him on his departure of the show,' said Ruwet.

That same night, Dr Olsen disappeared disappeared into the dark streets of Manhattan to discard his money and identification.

'He stated that he had done this because I had instructed him to do so since I was with him,' Ruwet penned.

'I told him that I wasn't with him; he said, 'Yes, that's right. I must've been dreaming.'

The two returned to Washington DC, but Dr Olson's state of mind became worse. He pleaded to be turned over to the police since they were already after him.

With this happening, Dr Olsen returned to New York to see the psychiatrist again.  

'This was the last time I saw Dr Olson,' Ruwet shared.

But the two spoke over the phone as they were planning for Dr Olson to admit himself into Chestnut Lodge in Rockville, Maryland, and they had reservations to go together.

'Dr Olson appeared on the phone quite relaxed,' said Ruwet. 'He told me about the trip in the morning, about the fact that they had reservations at Chestnut Lodge.'

The scientist even urged him not to go because 'he knew that [Ruwet] probably had to do work around the house' as it was a Saturday.

'I told him to think nothing of that and that I would meet him,' Ruwet stated. 'He said, fine. I'll see you in the morning.'' 

Dr Olson's family believes that he had 'grown uncomfortable with the nature of his work, showed signs of being a security risk, and then was made unstable when drugged with LSD at an offsite business meeting intended to test his trustworthiness.'

'He had become a man who knew too much,' according to his nephew, Paul Vidich. 

The New York District Attorney's Office reopened its file on Olson's death in 1996, eventually changing the cause of death from 'suicide' to 'unknown' after a long investigation.
