Chilling Discovery Made in Search for Missing Grad Student

Human remains have been found in the hunt for missing University of South Florida doctoral student Nahida Bristy.

The 27-year-old is presumed dead after going missing on April 16. Since then, the remains of her friend Zamil Limon, 27, were found in multiple black trash bags on a Florida bridge, and his housemate, 26-year-old Hisham Abugharbieh, has been arrested after a standoff with SWAT.

Abugharbieh is now charged with two counts of premeditated first-degree murder with a weapon.

The Hillsborough County Sheriff’s Office said that the latest set of remains was found near Interstate 275 and 4th Street North, on the west end of the Howard Frankland Bridge in St. Petersburg.

They add that they were now with the Pinellas County Medical Examiner’s Office but had not yet been identified.

Court documents seen by CBS News say Abugharbieh asked ChatGPT several questions that could be relevant to the case, including about how to dispose of a body, whether you can change the license plate on a car, and keeping a gun without a license.

The documents say he allegedly asked the artificial intelligence program what would happen if a person was “put in a black garbage bag and thrown in a dumpster.”

The documents add that Limon’s remains were found on the Howard Frankland Bridge “within numerous black utility trash bags in advanced stages of decomposition.”

They add that it is believed that chemical engineering student Bristy was “disposed of in a similar way.”

On April 17, Abugharbieh’s phone was traced to the part of the bridge where Limon’s remains were found.

Meanwhile, an autopsy found that he had died from “multiple sharp force injuries,” while Abugharbieh was found with numerous lacerations on his legs.

“Significant” traces of blood have also been found at the home, the documents add, including “two distinct patterns on the floor which appeared to have a relatively human-sized shape.”

The sheriff’s office had previously changed the status of both Limon and Bristy to “endangered.”

Abugharbieh was arrested on Friday while wearing only a towel.

He now faces a slew of charges, including failure to report a death, unlawfully moving a dead body, evidence tampering, domestic violence battery, and false imprisonment.

He returns to court on Tuesday.

🔎 SEARCH BREAKTHROUGH: Body Matching Nahida Bristy’s Description Located After Multiple Grid Sweeps — 4-Inch Tear Along the Sleeve Raises New Forensic Questions

Hillsborough County and Pinellas County authorities have made a significant breakthrough in the search for 27-year-old Nahida Sultana Bristy, the University of South Florida (USF) doctoral student missing since April 16, 2026. After multiple grid sweeps and nearly 72 hours of expanded operations involving dive teams, boats, and K-9 units, investigators recovered human remains in the waterways south of the Howard Frankland Bridge that match Bristy’s description.

The body was found wearing clothing consistent with what Bristy was last seen wearing on university surveillance footage around 10:03–12:08 a.m. (reports vary slightly on the precise timestamp) — specifically a light pink long-sleeve shirt, long black loose pants, and sneakers with white bottoms. However, what is now drawing intense attention from detectives is a 4-inch tear along the sleeve of the pink shirt that does not appear to match earlier witness descriptions or the condition of the clothing captured on video when she left her office building on the USF Tampa campus.

Details from the Recovery Scene

The remains were located on April 26 in the area of Interstate 275 and 4th Street North on the St. Petersburg side of the Howard Frankland Bridge — the same general vicinity where the remains of fellow USF doctoral student Zamil Limon, also 27, were recovered on April 24. According to newly referenced affidavit details, the discovery occurred during systematic grid searches of previously swept zones, underscoring the persistent challenges of aquatic evidence recovery in Tampa Bay’s tidal and current-driven environment.

While the overall outfit aligned closely with Bristy’s last known attire (including the light pink long-sleeve top), the documented 4-inch tear along the sleeve has introduced new questions. Investigators are now examining whether the tear resulted from:

Struggle or defensive action during the alleged attack
Post-incident handling or disposal process
Environmental factors such as debris, marine life, or dragging along structures after entering the water
Natural tearing due to decomposition and water exposure

This anomaly did not align with prior descriptions provided by witnesses or the clear surveillance images showing Bristy walking north from her building while holding an umbrella. The tear is being treated as potential forensic evidence that could help reconstruct the sequence of events.

Link to the Ongoing Double Homicide Investigation

Hisham Saleh Abugharbieh, 26, Limon’s roommate, faces two counts of first-degree premeditated murder with a weapon in the deaths of both Bristy and Limon. Court documents allege significant blood evidence linked to both victims was found in the shared apartment, along with Bristy’s personal items such as her USF ID and credit cards discovered in Limon’s bedroom. Cellphone data, license plate readers, and surveillance have reportedly placed the suspect in the bridge area.

Prosecutors have also referenced Abugharbieh allegedly querying an AI tool about methods for body disposal and purchasing black trash bags prior to the students being reported missing. Limon’s remains were found inside or near such bags, and authorities have stated that Bristy appears to have been “disposed of in a similar way.”

The 4-inch sleeve tear adds another physical layer to the evidence. In violent crime cases, damage to clothing — especially on long-sleeve garments that could cover arms during defensive movements — often provides insight into the dynamics of an assault. Forensic experts will likely analyze the tear’s edges, direction, and any associated fibers or biological material.

Suggested image: Respectful portrait-style illustrations or public references to Nahida Bristy and Zamil Limon as 27-year-old doctoral students (Bristy in chemical engineering, Limon in geography and environmental science). Both were international students from Bangladesh and were reportedly close friends considering marriage. Pair with a sensitive rendering of law enforcement personnel conducting professional water searches near the bridge to convey the scale of the operation without graphic detail.

Challenges of the Multi-Day Search

The recovery followed an expanded overnight search covering more than six square miles around the USF campus and adjacent waterways. Previous sweeps had covered the area, yet the body was ultimately located during subsequent grid efforts, a common occurrence in complex bay recoveries where visibility is limited and conditions change with tides.

A previously noted detail in related affidavits mentioned a second clothing item separated by about 11 feet, and later reports referenced one shoe found roughly 18 feet away. The new 4-inch tear fits into this pattern of dispersed or damaged evidence, prompting further analysis of water currents, disposal mechanics, and timeline reconstruction.

Community and Family Impact

The double tragedy has deeply affected the USF community, particularly among international and graduate students. Both Bristy and Limon were pursuing advanced degrees and represented promising academic talent. Bristy’s family in Bangladesh was reportedly informed by investigators of the high likelihood of her death based on the volume of blood evidence in the apartment, though formal identification of the remains continues through the Pinellas County Medical Examiner’s Office.

USF has offered counseling resources and issued statements expressing sorrow for the loss of two dedicated scholars. The case has also sparked broader conversations about safety in shared student housing and support for international students.

Next Steps in the Investigation

With the body recovered and clothing details under close examination, authorities are prioritizing:

Positive identification via DNA, fingerprints, or dental records
Detailed forensic analysis of the 4-inch sleeve tear and any other damage
Cross-referencing with digital evidence, including phone data and the previously recovered student phone
Autopsy findings to determine cause and manner of death

Abugharbieh remains held without bond as the case proceeds toward trial. Additional charges related to evidence tampering and unlawful handling of human remains are also possible.

The 4-inch tear, while a seemingly small detail, could prove significant in court by helping to establish the nature and timing of the alleged violence. As more affidavit information becomes public, this anomaly is expected to feature prominently in discussions of premeditation and the sequence of events on April 16.

This developing case continues to unfold with law enforcement emphasizing the need for any additional witness information, particularly dashcam footage or observations from the Howard Frankland Bridge area in the hours following the students’ last known sightings.
