AI-generated · every claim is source-linkedConfirmed Threat
On April 16, 2026, USF doctoral students Zamil Limon and Nahida Bristy, both 27, were last seen near the Tampa campus. After a family friend was unable to reach Bristy, the University of South Florida Police Department was notified at approximately 4:50 PM EDT on April 17, 2026, and a parallel report was made to the Hillsborough County Sheriff's Office. Both students were entered into FCIC/NCIC missing-persons databases, and USF Police pushed a missing-student alert to media. Their status was upgraded to 'endangered' on April 23, and Limon's roommate Hisham Abugharbieh was arrested April 24 and charged with two counts of first-degree murder.

Verified verbatimVerbatim from USF President Moez Limayem's official 'Honoring Nahida Bristy and Zamil Limon' campus message dated April 29, 2026348 chars
As we continue to mourn the tragic loss of our students Nahida Bristy and Zamil Limon, I want to share several updates with you, including plans to honor Nahida and Zamil with the dignity and compassion they deserve. Nahida and Zamil were exemplary students, building lives, creating community and contributing to our university in meaningful ways.
An official campus message from USF President Moez Limayem dated April 29, 2026, five days after Limon's body was recovered and three days after Bristy's remains were found
A memorial and update message rather than an emergency notification; by April 29 the university publicly treated both students' deaths as established, the day before Bristy's remains were positively identified on Thursday, April 30, 2026 (publicly announced May 1)
Context
Background
The University of South Florida is a public R1 doctoral institution in Tampa, with about 50,000 students. On the morning of Wednesday, April 16, 2026, two USF doctoral students (Zamil Limon, age 27, and Nahida Bristy, age 27, both originally from Bangladesh) were last seen in the Tampa area. Limon was last seen at his home about three blocks from USF; Bristy was last seen later that morning at the Natural and Environmental Sciences building on USF's Tampa campus. On April 17, 2026 at approximately 4:50 PM EDT, a family friend notified USF Police after being unable to reach Bristy. USF Police entered both students into FCIC/NCIC missing-persons databases and released a missing-student notification to media. On April 23, 2026, both students' status was upgraded from 'missing' to 'missing and endangered' when investigators received new information. On April 24, 2026, Limon's roommate Hisham Abugharbieh was arrested at a domestic-violence call at his parents' home in Lutz, Florida, and Limon's body was located in a trash bag on the Howard Frankland Bridge. Bristy's remains were discovered Sunday, April 26, 2026 by a fisherman in a kayak in a black trash bag in the shoreline mangroves south of the Howard Frankland Bridge (about two days after Limon's body was found nearby) and were positively identified on Thursday, April 30, 2026, with the announcement made on May 1. Abugharbieh was charged with two counts of first-degree premeditated murder, plus charges of moving a dead body, tampering with evidence, false imprisonment, and battery. The case became one of the most-watched university missing-student investigations in years and underscored both the importance and limits of Higher Education Opportunity Act missing-student notification protocols, protocols that worked exactly as designed but could not prevent the underlying crime.
Analysis
Key Findings
USF's missing-student notification was issued within the 24-hour HEOA-mandated window after a family friend reported the students unreachable, demonstrating the federal compliance framework working as designed
Limon and Bristy were doctoral students rather than residence-hall undergraduates, illustrating that the HEOA missing-student framework (though specifically applied to on-campus housing residents) extends in practice to all enrolled students
The 'endangered' status upgrade on April 23 (7 days after disappearance) correlates to the moment FCIC/NCIC investigators received critical new information that led to Abugharbieh's arrest the next day
The case represents the rare missing-student notification that becomes a homicide investigation, a category that the HEOA framework was designed to surface as quickly as possible to enable interagency response
Investigators reportedly disclosed that Abugharbieh had used ChatGPT in the days before the killings to ask what would happen if a human body was placed in a garbage bag and thrown in a dumpster
Outcome
Both students were ultimately found deceased. Zamil Limon's body was recovered April 24 from the Howard Frankland Bridge area in a trash bag. Nahida Bristy's remains were [recovered Sunday, April 26 by a fisherman in a kayak in a black trash bag in the shoreline mangroves south of the Howard Frankland Bridge](https://www.tampabay.com/news/crime/2026/05/01/tampa-missing-usf-students-murders-zamil-limon-nahida-bristy/) and [positively identified on Thursday, April 30, 2026 (announced May 1)](https://www.cnn.com/2026/05/01/us/usf-student-nahida-bristy-death). Limon's roommate, Hisham Abugharbieh, 26, was arrested at his parents' home in Lutz, Florida on April 24 after a domestic-violence call and was charged with two counts of first-degree premeditated murder with a weapon, plus charges of unlawfully moving a dead body, failure to report a death with intent to conceal, tampering with physical evidence, false imprisonment, and battery.
