In a wealthy, manicured suburb of Milwaukee, Wisconsin, the respected Filipino-American doctors Jefferson and Elnora Calimlim lived in a sprawling $1.2 million mansion, the very picture of immigrant success. But deep in the basement of their home, they kept a dark secret for nineteen years: a Filipina domestic helper named Irma Martinez, who lived a life of near-total isolation and servitude.

The story of her captivity and eventual rescue is a shocking tale of exploitation, but it is also a complex case that pitted American law against the powerful Filipino cultural value of utang na loob, or debt of gratitude.

The ordeal began in 1985. The Calimlims, struggling to balance their demanding careers with raising three young children, recruited 19-year-old Irma from a poor village in Camarines Sur, Philippines. They brought her to the United States on a fraudulent visa under the false pretense that she needed medical surgery, promising her that they would process her green card so she could stay legally. For Irma, it was a golden opportunity. For the Calimlims, it was the beginning of a 19-year deception.

Irma’s life in the Brookfield mansion was one of a ghost. She worked from 6 AM to 11 PM daily, cooking, cleaning, and caring for the children. She was forbidden from leaving the house alone, and when guests were over, she was either introduced as a “visiting relative” or ordered to hide in her basement room. Her mail was censored, and she was denied dental care for a painful toothache.

For this tireless labor, she was paid a pittance—$150 a month for the first decade, later raised to $400. While a meager sum in the US, the money she sent home was life-changing for her family in the Philippines, paying for education, medical care, and property—a fact that created a powerful, unspoken pressure for her to endure her situation.

For nearly two decades, the secret was kept, even by the Calimlims’ own children, who grew up calling Irma “Tita” (Auntie) and were instructed never to speak of her to their friends. The family’s perfect facade only began to crack when their youngest son, Jack, became engaged to Sherry Bantic, a Filipino-American beauty queen.

Sherry quickly grew suspicious of the “aunt” who never seemed to leave the house and was treated more like staff than family. She befriended Irma and learned the heartbreaking truth of her servitude. After her own marriage to Jack lasted only seven months, Sherry, unable to live with the secret, contacted US immigration authorities.

In September 2004, federal agents raided the Calimlim mansion and rescued Irma. The case that followed was a sensation, not just for the crime itself, but for the shocking reaction of the local Filipino community. Many rallied in support of the Calimlims, writing letters to the judge and holding prayer vigils. They argued that this was not slavery but a culturally acceptable arrangement. In their view, Irma had a “debt of gratitude” to the doctors for lifting her family from poverty.

The American prosecutor, Susan French, vehemently disagreed. She argued the motive was pure financial greed, calculating that the Calimlims had saved hundreds of thousands of dollars in fair wages over 19 years by exploiting Irma’s vulnerability and her fear of deportation.

In 2006, a jury found the Calimlims guilty of forced labor. The judge sentenced them to four years in federal prison and ordered them to pay over $900,000 in restitution and damages. In a final twist, it was discovered the Calimlims were not US citizens themselves, and after serving their sentences, they were deported back to the Philippines.

Irma Martinez, after a 19-year ordeal, was finally granted the green card she had been promised. She received a large sum of her stolen back wages and, for the first time in her adult life, was free to begin a life of her own.
