In 1946, orphans, prisoners and prostitutes in Guatemala were selected for a horrific experiment.

Scientists infected approximately 1,500 Guatamalens with syphilis, gonorrhea and chancroid, all of which are sexually transmitted illnesses, to test an antibiotic called penicillin.

Marta Orellana, one test subject, tells her story…

Marta was playing with her friends at the orphanage. She heard, “Orellana to the infirmary. Orellana to the infirmary” and rushed to see why she was called.

Several doctors, tall and fair, stood with syringes in their hand.

They ordered her to lie down and spread her legs. She locked her knees and shook her head. One medic slapped Orellana and she began to cry. She had no choice. She did as she was told.

Mrs Orellana spent the majority of her life knowing something was wrong, but she was never told the purpose of the study.

The scientists treated 87% of those infected with syphilis; they lost track of the remaining 13%.

Whilst the majority of the test subjects may not be alive, there could be hundreds of infected children and grandchildren…

The medics broke the Hippocratic oath and in my eyes, this is a heinous crime. Traumatizing thousands to 'save millions' is not right.

Arridy was tested with an IQ of 46 by 3 state psychologists and was put in a school for mentally defectives as a kid. Arridy lacked the understanding of the crime that was committed, the confession he made and the execution itself. It's believed that he didn't understand right from wrong. The testimonies he gave were inconsistent and the prime suspect Frank Aquilar had already been arrested. Despite this, Arridy was convicted of murder and was sentenced to death by gas chamber
