The remains of a 27-year-old University of South Florida doctoral student missing for more than a week have been identified, authorities announced May 1.

Nahida Bristy’s body was located Tuesday, April 26 in the Tampa Bay area near Interstate 275 and Fourth St. North, according to the Hillsborough County Sheriff’s Office. Investigators conducted an extensive search of the area after the remains of fellow USF doctoral student Zamil Limon were located the morning of April 24 on the nearby Howard Frankland Bridge.

Hillsborough County Sheriff Chad Chronister said in a Friday, May 1 news conference that it took several days to positively identify Bristy because of the condition of her body. Like Limon, Bristy also was stabbed.

“The details of this investigation are gruesome and the actions of the suspect are nothing short of pure evil,” Chronister said. “Our community has been left heartbroken, and the victims’ families, shattered after this tragic loss.”

The two students were last seen April 16 and were reported missing April 17.

Limon’s roommate, Hisham Abugharbieh, 26, was arrested the day Limon’s decomposing body was found in black trash bags. Abugharbieh was charged April 25 with two counts of premeditated murder in the first degree with a weapon.

The charges came before Bristy’s body was found. In court documents filed over the weekend, authorities said there is essentially no “probability Nahida Bristy remains alive.”

Two recreational kayakers who were fishing April 26 had one of their lines snag a bag in the mangroves of the water. As they got closer, they smelled an “indescribable” odor. As they got closer to remove the fishing line, they saw the bag was open and it appeared to contain human remains. The kayakers then contacted law enforcement.

Limon’s death was because of “multiple sharp force injuries,” the Pinellas County Medical Examiner ruled.

What was the motive for the killings of two USF student murders?

Chronister said investigators are still working to determine a motive.

“They are anxiously searching for that as well,” Chronister said. “I hope we find that out.”

The sheriff added that Abugharbieh was talkative and “loved to talk about himself,” but clammed up, becoming “elusive and deceptive” when talks turned to the victims.
