Flor Ramos Contemplacion was born on January 7, 1953, in San Pablo City, which is in the Laguna province of Luzon, Philippines. She was the second youngest of ten children in her family. When Flor was only 7 years old, her father passed away. This event put a lot of financial pressure on her family, who lived in a rural area. Because of this, when she turned 10, Flor moved to Manila to live with her older sister.

Flor's education was cut short when she dropped out of school at the age of 12. Shortly after leaving school, she started working as a housemaid to help support her family. At 19, in 1972, she got married and eventually had four children. However, in 1987, her husband left the family, and Flor became the sole breadwinner for her children.

In 1988, seeking better job opportunities, Flor traveled to Singapore. There, she found work as a domestic servant in a residential area called Cardiff Road in Serangoon. In her job, she often worked long hours, from 6 am until midnight, taking care of household chores and looking after her employer's child.

On May 4, 1991, Delia Mamaril Maga was found dead in her apartment in Singapore. She was a 34-year-old Filipino domestic worker. Alongside her body was a three-year-old boy named Nicholas Huang, whom Maga had been caring for. The situation alarmed the boy's parents when they arrived home to discover both victims. Their two-year-old daughter was found unharmed in a separate room.

When police examined the crime scene, they noted there were no signs of a struggle. The locked front door suggested that Maga knew her killer. Neighbors reported that Maga had mentioned a friend would visit her that morning. Later that day, police arrested Flor Ramos Contemplacion, a 38-year-old Filipino woman. She was found with valuables believed to belong to Maga.

During police questioning, Contemplacion initially claimed she had been out running an errand. However, her alibi did not check out. On May 5, she confessed to killing both Maga and Huang. By May 7, she was charged with their murders and placed in custody.

The trial began on January 26, 1993. Prosecutors explained how the victims were found. An expert witness confirmed that Maga died from strangulation while Huang drowned. Contemplacion provided a confession detailing her actions. She stated that after a psychotic episode, she strangled Maga and then drowned Huang.

Despite her confession, Contemplacion's lawyer argued that it was made under pressure. Contemplacion claimed police used fear tactics during her interrogation. However, the judge ruled that all statements were given voluntarily.

On January 29, 1993, she was found guilty of both murders and sentenced to death. She showed great emotion when the sentence was announced. Appeals were made regarding her mental state during the murders. During a retrial, she argued that she suffered from seizures that impaired her actions.

Multiple psychiatric assessments were conducted, with conflicting opinions about her mental health. Ultimately, the courts upheld her conviction, concluding that she was responsible for her actions at the time of the murders.

On March 17, 1995, Contemplacion was executed by hanging in Singapore. Her case created significant diplomatic tension between the Philippines and Singapore. Following her execution, there was public outcry in the Philippines, with many believing she was either innocent or not mentally fit to stand trial. The incident led to significant fallout in Filipino-Singaporean relations.
