Murder investigations can be a bit like an onion; you have to peel back the many layers to see the inner workings of the killers, the motive, the weapon at play: the perplexing puzzle.
At the University of Southern Florida, a double homicide investigation has been launched for the disappearance of two doctoral students, Zamil Limon and his girlfriend, Nahida Bristy. Both international students from Bangladesh were reported missing on April 16, 2026.
Zamil Limon, who was pursuing a PhD in geography and environmental science, was discovered on April 24, 2026, in heavy-duty trash bags on the Howard Frankland Bridge. Detectives have deduced that he was stabbed to death. He has been laid to rest at his home, Jamalpur, India.
Nahida Bristy, a doctoral student in chemical engineering, was found on 2 days later by a kayaker in a black trash bag whose fishing line got stuck in mangroves south of the Howard Frankland Bridge, close to where her boyfriend’s remains were located. Both sets of remains were identified through DNA analysis. In addition, both trash bags used have been a lead in identifying who committed the crime.
Limon’s roommate and former USF student, Hisham Abugharbieh, has been arrested for the deaths of Limon and 
Bristy and is charged with two counts of premeditated first-degree murder. As of mid-May 2026, prosecutors are seeking the death penalty for the former roommate. Authorities and prosecutors have not disclosed any motive for the crime yet; however, the police reports note there have been previous altercations between Limon, Bristy, and Aburgharbieh.
Disturbing court documents have revealed that the former roommate used ChatGPT days before the couple was reported missing, asking how to dispose of a body.
The University of South Florida president, Moez Limayem, spoke about the pair’s tragic ending in a speech. “As I reflect on this unimaginable situation, I find myself thinking not only as a university president, but as a parent and as someone who once came to this country as an international student. I remember what it meant for my own family to have me far from home, and how even small moments of silence could bring worry. I cannot begin to comprehend the pain that Nahida’s and Zamil’s families are enduring, but I want them – and all of you – to know that we are holding them close in our thoughts, and that their grief is shared across this university.”
As the season arrives for seniors to leave their high schools and attend different colleges, we, as students, need to reflect on the importance of being more mindful of potential dangers in risk assessments. Students often leave a little piece of themselves behind when they leave home to pursue their own goals and live their dreams. However, this recent tragedy has added an element to the already difficult assessment process. As a result, it has become apparent to all of us that we must confront the sobering reality of the unique vulnerabilities international scholars face as they navigate life without the support of their families. Keep close to your loved ones, regardless of whether they’re international students or not.
