Belize officials on Wednesday revealed the cause of death for three Massachusetts women who were found dead in their resort hotel room last month.

Authorities previously identified the women as Kaoutar Naqqad, 23, Imane Mallah, 24, and Wafae El-Arar, 26, after they were found dead on Feb. 22 at the Royal Kahal Beach Resort in San Pedro.

Gian Cho, executive director of the National Forensics and Science Services (NFSS), told local outlet Love FM that test results “revealed that the three victims all had fatal exposure to carbon monoxide.”

“So carbon monoxide … has been revealed as the contributing or the underlying exposure that led to the acute pulmonary edema, which was the final cause of death,” Cho said. “We did a very complete and comprehensive toxicology screening on the blood and liver tissues from these victims so that we can give the family a conclusive answer and closure as to what contributed to their death.”

“Our families and all who loved these women are shattered, struggling to comprehend this profound and sudden loss,” their families said. “With this statement, our families hope to honor Kaoutar, Imane and Wafae by telling the world about the girls we knew and loved.”

They went on to describe Mallah as a “radiant spirit, and a beacon of kindness.”

“She embraced life wholeheartedly, cherishing every soul that shared the journey with her,” the statement reads.

Naqqad’s “kindness and warmth touched everyone she met.”

“She was compassionate, caring, and deeply devoted to those she loved. Her heart was full of generosity, always putting others before herself and offering a listening ear, a comforting word, and unwavering support,” the statement says.

El-Arar “was full of life, dreams, and unwavering faith.”

“Her name, meaning faithfulness and loyalty, was a true reflection of who she was — honest, kind, and deeply devoted to the people she loved. Wafae
was a bright mind with a passion for women’s health,” her family said.
