Authorities have identified human remains found on Sunday, April 26, near a Tampa Bay bridge as those of Nahida Bristy, a doctoral student from the University of South Florida who had been reported missing.

The Hillsborough County Sheriff’s Office announced on Friday that DNA tests, along with dental records and clothing analysis, confirmed the remains belong to Bristy.

“We have located Nahida Bristy,” stated Hillsborough County Sheriff Chad Chronister. “We have informed her family and are making arrangements to return both bodies to their families in Bangladesh for religious reasons.”

Bristy, along with fellow doctoral student Zamil Limon from the University of South Florida, disappeared on April 16, within hours of one another. Limon’s body was found on April 24 on the Howard Frankland Bridge.

Nahida Bristy, who was pursuing a Ph.D. in chemical engineering, was last seen around 10 a.m. on April 16 at the NES Building on the USF Tampa campus.

“Although this identification provides closure, it is accompanied by profound grief. Nahida Bristy and Zamil Limon were not just students; they were talented, driven individuals with bright futures ahead,” expressed Chronister.

“We extend our condolences to their loved ones as they face this painful reality. We are committed to uncovering the truth and ensuring that justice is pursued in their name.”

Hisham Abugharbieh, Limon’s roommate, is in custody and has been charged with both murders, authorities said.

The 26-year-old faces charges, including domestic violence simple battery, domestic violence false imprisonment, tampering with evidence, failure to report a death to the medical examiner’s office or law enforcement and unlawfully holding or moving a human dead body in unapproved conditions.

According to the Hillsborough County Sheriff’s Office, Bristy was last seen on surveillance video at the University of South Florida at 12 p.m., and was reported missing the following day by a friend to the USF Police Department. Limon was reported missing the next day, and authorities took over the investigation April 22.

Investigators later searched Limon’s apartment, where they found his student ID, eyeglasses, a shirt with blood and tears and phone cases belonging to both victims. Authorities also deployed a marine unit and dive team to search areas of the last known GPS signals from the victims’ phones.

On Sunday, April 26, kayakers discovered the remains in mangroves near Interstate 275 and 4th Street North after a fishing line became caught on a trash bag. Authorities said the remains were in an advanced state of decomposition and required several days to identify.

Detectives said the investigation revealed blood evidence inside the apartment shared by Limon and the suspect, and they are continuing to work to determine a motive in what officials described as an active and ongoing investigation.
