Roommate charged with two counts of murder in death, disappearance of two USF students

A former University of South Florida student has been charged with killing his roommate and the roommate's girlfriend — two doctoral students from Bangladesh who disappeared earlier this month, authorities said Saturday.

Hisham Abugharbieh, 26, is facing two counts of premeditated murder in the first degree with a weapon in the deaths of Zamil Limon and Nahida Bristy, students at USF, according to the Hillsborough County Sheriff's Office. He made an initial court appearance Saturday in Tampa, where he was ordered held without bond. A hearing is set for April 28.

Limon’s remains were found on the Howard Frankland bridge Friday morning, but Bristy is still missing, Hillsborough County Chief Deputy Joseph Maurer said on Friday.

Abugharbieh, a native-born U.S. citizen, was initially taken into custody on Friday at his family’s home on preliminary charges that include unlawfully moving a dead body, failure to report a death, tampering with evidence, false imprisonment and battery. Online court records do not list an attorney for him. Messages were sent via email and phone to the public defender’s office in Hillsborough County.

Officers encountered Abugharbieh as they responded to a report of domestic violence at his family’s home, just north of the campus, and were able to move his relatives to safety. But then he barricaded himself inside and refused to come out. A SWAT team responded — along with a drone, a robot and crisis negotiators — before Abugharbieh came out with his hands up, apparently wearing nothing but a blue towel.

Limon and Bristy, both 27, were considering getting married, a relative said. They disappeared from campus on April 16. Limon was last seen at his home in an off-campus apartment complex where he lived with Abugharbieh. Bristy, who lived off campus, was last seen an hour later at a campus science building.

An autopsy is being done on the remains to determine the manner and cause of Limon’s death, and those results are expected Saturday morning, Maurer said Friday.

Abugharbieh had been a USF student but was not currently enrolled. University records showed he had attended the school from Spring 2021 through Spring 2023, and had pursued a BS in Management, a university spokesperson said.

Limon was studying geography, environmental science and policy, and Bristy was studying chemical engineering. She was a graduate of Noakhali Science and Technology University. The school, which spelled her last name as Brishti, said in a statement Saturday that she was a Ph.D. candidate and described her as a talented and promising student.

“Her sudden passing has deeply saddened all of us,” Vice Chancellor Mohammad Ismail said. "The university family pays deep respect to her memory. At the same time, we demand punishment for those involved in her death and compensation for the victim’s family.”

The search for Bristy continues. Anyone with information regarding her disappearance is asked to contact the Hillsborough County Sheriff’s Office.

Abugharbieh had several previous arrests, the sheriff’s office said. He was charged with battery and burglary of an unoccupied dwelling in September 2023, and with battery that May — both classified in court records as misdemeanors.

Court records show Abugharbieh entered into a diversion program for first-time offenders charged with misdemeanors. He completed the program in 2024 and the charges were discontinued. A phone call to his lawyer in that case was not immediately returned.

Hillsborough County Court records also showed two domestic violence petitions filed by a family member in 2023. A judge granted an injunction in one case and denied the other petition. He also was accused of traffic violations.

This story corrects that Bristy lived off campus.

JUNEAU, Alaska (AP) — A man with the same name and party affiliation as Alaska Republican U.S. Sen. Dan Sullivan on Monday challenged a decision by a top state elections official to disqualify his candidacy and remove him from the August primary ballot.

A court filing, on behalf of the challenger Sullivan by his attorneys, said the decision by Division of Elections Director Carol Beecher disqualifying him violates state and federal law. It asks that he be placed on the ballot. Sullivan, a retired teacher from the small fishing community of Petersburg, has maintained that he's a qualified candidate for U.S. Senate and that election officials lacked a legal basis to boot him from the ballot.

The U.S. Constitution lays out three exclusive qualifications for U.S. Senate, addressing age, citizenship and residency, his attorneys wrote.

“Nothing in Alaska law regulates in any way the private motivations that draw individuals to declare or campaign for office,” the filing by attorneys Jeffrey Robinson, Bryn Pallesen and Zoe Eisberg states.

Sullivan's entrance into the race, days before the June 1 filing deadline, drew condemnation from Sen. Sullivan and the National Republican Senatorial Committee. They called the challenger a sham candidate and alleged he was working with Democrats to boost Democratic former U.S. Rep. Mary Peltola’s chances in the race. Peltola’s campaign and state Democrats have denied the allegation, as has the challenger.

Sen. Sullivan and Peltola are the highest-profile contenders in a race with more than a dozen candidates. It's one of the most prominent U.S. Senate races in this year's midterm elections — one both parties consider crucial to their efforts to control the chamber.

Steve Kirch, a spokesperson for the division, said the agency had no comment and does not discuss “ongoing reviews, investigations or related proceedings.” Beecher has previously noted that ballots are due to be printed on Sunday.

On June 15, a week after Republican Lt. Gov. Nancy Dahlstrom announced an investigation into the challenger Sullivan’s run, Beecher disqualified him. She concluded that his declaration of candidacy “was not filed in order to declare an actual good-faith candidacy for the office of United States Senator, but was instead filed with a purpose to confuse or mislead and to thereby compromise the ballot’s fairness or neutrality.”

In announcing an investigation, Dahlstrom cited “credible allegations” that Sullivan declared his candidacy “in coordination with another candidate and campaign” with an intent to confuse and “manipulate” voters. But in removing the challenger from the ballot, Beecher did not mention finding any evidence of alleged coordination with Peltola or Democratic Party officials.

The challenger Sullivan, when asked in an interview with The Associated Press earlier this month if he'd had any contact with Peltola's campaign, responded ”zero, none, zilch.”

Beecher said she based her decision on factors including that he had registered to vote as Daniel J. Sullivan Jr. and in conjunction with his candidacy changed his party affiliation to Republican. She cited similarities between his campaign website and the senator’s, and his work with a consultant whose clients have included some Democrats.

The form congressional candidates in Alaska complete asks them how they would like to be referred to on the ballot and their preferred party affiliation.

Beecher said she acted in line with a regulation that says a candidate's name may not appear on a ballot with academic or professional titles or “in a manner that is confusing or misleading to voters or compromises the fairness or neutrality of the ballot.”

In response to questions from Democratic state Rep. Andrew Gray, legislative attorney Andrew Dunmire last week said the regulation cited by Beecher does not forbid placing Sullivan's name on the ballot. He said the elections division could comply with it by designing the ballot in a way that allows voters to distinguish between both Sullivans.

It’s a position echoed by the attorneys for the challenger Sullivan.

The challenger initially had been certified and listed on the state’s candidate list as Dan J. Sullivan. The senator was listed as Dan S. Sullivan and denoted as the incumbent.

Alaska has open primaries in which the top four vote-getters, regardless of party affiliation, advance to the ranked-choice general election.
