(TAMPA, Fla.) — Investigators have listed that two University of Southern Florida doctoral students who went missing last week are endangered as the search continues.
Zamil Limon and Nahida Bristy, both 27, were last seen at separate locations in the Tampa area on April 16, according to the USF Police Department.
Officials received new information to warrant the upgrade to an endangered status, which indicates they are at risk of physical injury or death, the Hillsborough County Sheriff’s Office said Thursday.
The sheriff did not provide any more details about the investigation or search efforts.
Limon and Bristy are friends, and a mutual acquaintance reported them missing, campus police said.
Limon, who is pursuing a degree in geography, environmental science and policy, was last seen at his Tampa residence at approximately 9 a.m. on April 16, according to police.
Bristy, who is studying chemical engineering, was last seen at the USF Tampa campus at the Natural & Environmental Sciences Building at approximately 10 a.m. that day, police said.
Both students have been entered into state and national missing persons’ databases.
Anyone with information on their whereabouts is urged to call the University of South Florida Police Department at 813-974-2628.

(NEW YORK) — Two improvised explosive devices brought to a counterprotest outside Gracie Mansion in New York City Saturday are being investigated as “an act of ISIS-inspired terrorism,” and the two suspects arrested in connection with the incident are facing federal terrorism charges, New York Police Commissioner Jessica Tisch said Monday.
According to a federal criminal complaint released Monday, both suspects openly pledged allegiance to ISIS while in the presence of police, and one suspect allegedly told officers they “wanted to carry out an attack bigger than the Boston Marathon bombing,” which the suspect noted “caused only ‘three deaths.’”
The explosive devices contained the volatile substance triacetone triperoxide, known as TATP, and were made to “injure, maim or worse,” Tisch said of Saturday’s incident.
“These were not hoax devices or smoke bombs. They were improvised explosive devices,” Tisch said during a news conference outside the Gracie Mansion mayor’s residence with New York City Mayor Zohran Mandami, the city’s first Muslim mayor.
One of the devices was ignited and deployed at protesters in a crosswalk on East End Avenue and East 87 Street, and the other device was detonated close by, Tisch said.
Tisch said a third suspected IED was found in the car of the two suspects, a black 2010 Honda with New Jersey license plates, parked on the Upper East Side of Manhattan near Gracie Mansion, prompting an immediate evacuation of homes in the area. She said the device did not test positive for explosives.
All of the devices are being sent to the FBI lab in Quantico, Virginia, for additional testing, Tisch said.
Two Pennsylvania men who are in custody are charged in a five-count federal complaint with attempting to provide material support and resources to ISIS, use of a weapon of mass destruction, transportation of explosive materials, interstate transportation and receipt of explosives, and unlawful possession of destructive devices.
The suspects were identified as Emir Balat of Langhorne, Pennsylvania, and Ibrahim Kayumi of Newton, Pennsylvania, according to Tisch and the federal complaint.
The suspects were ordered to be held without bail after they made their initial appearances, both in shackles, in Manhattan federal court on Monday afternoon. They did not enter a plea to the charges.
“They’re suspected of coming here to commit an act of terrorism,” Mamdani said Monday. “Let me say this plainly: Anyone who comes to New York City to bring violence to our streets will be held accountable in accordance with the law.”
The explosives were deployed at an anti-Muslim protest outside Gracie Mansion that was organized by far-right, anti-immigrant provocateur Jack Lang, officials said. The event was called “Stop the Islamic Takeover of New York City.”
The anti-Muslim protest drew counterprotesters who called their response “Run Nazis Out of New York City,” according to the criminal complaint.
“FBI’s Joint Terrorism Task Force is investigating the matter with our partners at NYPD as well as the U.S. Attorney’s Office for the Southern District of New York,” the FBI said in a statement Sunday.
Balat and Kayumi are suspected of attending the event as part of the counterprotest to the anti-Muslim demonstration, authorities said Monday.
Neither Mamdani nor his wife, Rama Duwaji, were in Gracie Mansion when the incident occurred, the mayor said Monday.
Immediately following his arrest, Kayumi was asked by someone in the surrounding crowd why he allegedly attempted to bomb the protest, according to the complaint.
“Kayumi responded in part and as captured on NYPD body-worn camera footage, ‘ISIS,'” the complaint states.
Balat waived his Miranda rights to remain silent following his arrest, according to the complaint, and allegedly provided a written statement in which he “pledge[d] [] allegience [sic] to the Islamic State,” the complaint states.
Balat also allegedly told police that “they wanted to carry out an attack bigger than the Boston Marathon bombing, which Balat noted caused only ‘three deaths,'” according to the complaint.
The April 15, 2013, Boston Marathon bombing also left more than 500 people injured.
Kayumi, whom the complaint said also waived his Miranda rights, allegedly “stated, in substance and in part, that he was affiliated with ISIS; watched ISIS propaganda on his phone; and was partly inspired to carry out his actions that day by ISIS,” according to the complaint.
“Anti-Muslim bigotry is nothing new to me, nor is it anything new for the one million or so Muslim New Yorkers who know this city as our home,” Mamdani said at Monday’s news conference.
“While I found this protest appalling. I will not waver in my belief that it should be allowed to happen. Ours is a free society, where the right to peaceful protest is sacred. It does not only belong to those we agree with. It belongs to everyone,” Mandani added.
Many of the counterprotesters on Saturday confronted the “display of bigotry,” the mayor said. He also praised NYPD officers who swiftly responded to the incident and arrested the suspects, saying they were “faced with a chaotic situation that quickly could have become far more dangerous.”
The mayor specifically cited the “courageous and selfless” acts of two NYPD officers, Assistant Chief Aaron Edwards and Sgt. Luis Navarro, who attended Monday’s news conference. Mamdani said the officers “ran towards the danger so that others could run safely.”
Tisch said the last incident in New York City in which an IED was deployed occurred in December 2017, when Akayed Ullah detonated a homemade bomb he had strapped to his torso in a pedestrian underpass connecting the Port Authority Bus Terminal to the Time Square subway station.
Ullah, a permanent resident of Bangladesh who was living in Brooklyn at the time, was the only person injured in the act, which federal prosecutors said was committed on behalf of ISIS of Iraq. Ullah was convicted in April 2021 by a federal jury on all six counts of the indictment and was sentenced to life in prison.

(NEW YORK) — Police arrested four people after a smoke-generating “suspicious device” was thrown during a protest at the New York City mayor’s residence Saturday.
It was not immediately known if Mayor Zohran Mamdani or his wife, Rama Duwaji, were inside Gracie Mansion at the time. Mamdani had no public events announced but was in the city, according to his public schedule released Friday night.
Police sources told ABC News that the anti-Muslim protest was organized by a “known agitator.”
The NYPD bomb squad was investigating if the device was a smoke bomb, after some smoke started coming out of the device before the crowd was moved back, sources said.
No injuries were reported during the incident.
The mayor’s office did not immediately return messages to ABC News for comment.
Two unidentified people arrested were accused of throwing a suspicious device, police sources said.
One person was arrested for disorderly conduct and another person was arrested for deploying pepper spray, according to sources.

(NEW YORK) — The FBI said it is investigating a possible terrorism motive in a mass shooting early Sunday outside a bar in Austin, Texas, that left two people dead and more than a dozen others injured.
The suspected gunman was killed in a confrontation with police officers, who were already staged in the city’s entertainment district when the shooting broke out, Austin Police Chief Lisa Davis said at a news conference on Sunday.
The suspect has been identified as Ndiaga Diagne, a 53-year-old naturalized U.S. citizen who was born in Senegal, sources with knowledge of the matter told ABC News.
Davis said the suspect was living in Pflugerville, Texas.
The suspect was wearing clothing that referenced Allah and a T-shirt that referenced Iran, with an Iranian flag underneath the word, according to multiple law enforcement officials.
Diagne entered the U.S. in March 2000, on a B-2 tourist visa. In 2006, he adjusted to lawful permanent resident (IR-6) based on marriage to a U.S. citizen, according to multiple law enforcement officials.
He naturalized as a U.S. citizen in 2013.
In 2022, he was arrested in Texas for a collision with a vehicle damage, a source told ABC News.
Alex Doran, the acting special agent in charge of the FBI’s San Antonio field office, said a motive for the shooting remains under investigation, but terrorism is a possible motive.
“There were indicators on the subject and in his vehicle that indicate potential nexus to terrorism,” Doran said Sunday. “Again, it’s still too early to make a determination on that.”
In a social media post on Sunday afternoon, White House press secretary Karoline Leavitt said that President Donald Trump had been briefed regarding the shooting in Austin.
Davis said 911 callers began reporting a shooting on West Sixth Street in downtown Austin just before 2 p.m. She said the 911 callers stated that someone was shooting around Buford’s Bar.
“We know that a large SUV drove several times around the block in that area,” Davis said. “At one point, [the suspect] put his flashers on, rolled down his window and began using a pistol, shooting out of his car windows, striking patrons of the bar that were on the patio and that were in front of the bar.”
Davis said the suspect then parked his vehicle, got out and opened fire on people gathered on the sidewalk.
She said the Austin police department had a contingent of officers assigned to patrol the area in the busy West Sixth Street entertainment district. She said the officers were about 55 to 56 seconds away from where the suspect was shooting, and rushed toward the gunfire.
Davis said the suspect was walking in the direction of the police when officers confronted him and killed him.
Bystander video verified by ABC News captured the suspected shooter walking on the sidewalk toward police officers as he fired a barrage of shots. The video shows officers returning fire, striking the suspect before he falls to the ground as someone screams in the background, “Oh, my God!”
The sources told ABC News that the suspect initially fired five to seven shots from a handgun into a crowd of people before police said he exited his vehicle and was confronted by Austin Police officers.
“There is no question in my mind that the quick response of the police officers and of our EMS personnel and those professionals made a difference and saved lives,” Austin Mayor Kirk Watson said at the news conference.
Three Austin Police Department officers encountered a suspect armed with a gun on the street near Buford’s Bar, police said at an earlier news conference. The officers returned fire, fatally shooting the man, police said.
The FBI’s Joint terrorism Task Force is joining the investigation into the shooting, sources familiar with the matter told ABC News.
Law enforcement is also probing whether there were any mental health issues related to the suspected shooter, sources said, adding that as of now the shooting is considered an isolated incident, rather than part of a larger plot.
ABC News spoke via telephone with a woman in Texas, who confirmed that she is Diagne’s ex-wife. She said they divorced in 2022 and that she has not spoken to her ex-husband in four or five years. The woman said she knew nothing about the Austin shooting and said she was shocked when she heard about it.
Asked if her ex-husband was religious, she said, “He was religious, yeah.” She did not elaborate.
She said they previously lived in New York together and then, in 2017, moved to Texas because Diagne wanted more space for their family, including their two children. She said that before moving to Texas, her ex-husband went there for a week to check it out as a possible place to move, and then he came back to New York and told her, “Oh, I think you’re gonna love it, it’s quiet.”
She said they initially moved to San Antonio.
The Austin Police Department had earlier released a statement urging people to avoid the area near the 600 block of Rio Grande Street, the Downtown Austin block where the bar is located.
Photos and videos from the scene showed a major emergency response. Paramedics and officers arrived on the scene less than a minute after the first call came in, Chief Robert Luckritz, of the Austin-Travis County EMS, said on Sunday.
Three people, including a suspect, were pronounced dead at the scene, Luckritz said, adding that another 14 were transported to local hospitals for treatment for injuries.
Texas Gov. Greg Abbott said in a statement on Sunday that he has directed the state Department of Public Safety (DPS) to increase patrols in the West Sixth Street area during the weekends.
Abbott said that before the shooting, he directed the DPS and the Texas National Guard to intensify patrols and surveillance across the state in a precautionary measure in response to the joint U.S.-Israel military operation in Iran.
“This act of violence will not define us, nor will it shake the resolve of Texans,” Abbott said of the mass shooting. “To anyone who thinks about using the current conflict in the Middle East to threaten Texans or our critical infrastructure, understand this clearly: Texas will respond with decisive and overwhelming force to protect our state.”
