It reads like a scene out of a movie. 

On April 11, Chief Medical Officer, Dr. Kwasi Nyame allegedly entered Guam Memorial Hospital with an unloaded gun, calling it a “security test.” 

No warning, no coordination with police, and no heads-up to terrified staff.

An anonymous letter sent on June 4 to the GMHA Board of Trustees states that, “The 'test' was conducted without any warning, violating basic standards of safety and putting lives at unnecessary risk.”

But what may be more alarming? The response, or lack thereof, from GMHA’s top brass.

The letter added, "Rather than condemn the action, CEO Lillian Perez-Posadas defended Dr. Nyame's behavior, downplaying the seriousness.”

In an interview with KUAM on May 22, Posadas said the mock exercise was to increase the awareness of their security and that the Guam Police Department was not informed of the exercise because it was internal and small scale.

The small-scale exercise involved Dr. Nyame entering the hospital with an unloaded weapon tucked in his waistband.

The letter, sent anonymously due to fear of retaliation, was addressed to every GMHA board member. 

The writer says leadership tried to sweep the incident under the rug.

It doesn't stop with the CEO. The letter accuses GMHA’s legal team and executive leadership of complicity in a cover-up and calls for their immediate resignation.

Stating, “Leadership has a duty to protect both staff and patients...in this instance, that duty was abandoned."

The author says the incident and the hospital’s response has shattered employee trust.

"Many of us within GMHA feel unsafe, unheard, and unsupported,” the letter added. 

KUAM has learned Adelup also received a copy of the letter, when asked if they had any comment, Director Of Communications, Krystal Paco-San Agustin said 'none.'

KUAM also reached out to Posadas for comment who said, "I have many comments, thoughts, and views regarding the letter; however, the letter is addressed to the board, I will defer making any public comments."
